Used primarily to clear flat areas, such as stepped terrain or building tops. The Surface Finish Shallow operation cuts geometry whose slope angle does not exceed a threshold users can set maximum.
This operation is often paired with a flat endmill for use on stepped topography and building tops. Users can dramatically reduce machining time by strategically using larger diameter tools to cut open areas, while targeting small diameter tools to narrower channels.
Used primarily to clear sloped areas, such as rolling topography. The Surface Finish Constant Scallop operation cuts geometry by dynamically adjusting stepover users can set maximum as a function of the slope angle for any given point along the drive surface. This method maintains a uniform scallop height across variable relief, and thus uniform smoothness. This operation is often paired with a ball endmill for use on rolling topography and gentle slopes. Used to cut flat-bottomed holes, such as building footprints.
The Pocket operation removes material from within a closed chain, creating recesses with flat bottoms. Note that t he Pocket operation includes its own internal Roughing and Finishing stages within the parameters.
This operation is often paired with a flat endmill to cut building footprints. Pockets are preferred over Surface Finish Shallow for cutting deep, flat-bottomed recesses due to their incorporation of incremental depth cuts. Used to trace linear features, such as final perimeter cut-out.
The Contour operation cuts along a chain or series of chains. The cut may be compensated to the left or right of the chain s , or on center if compensation is turned off. The chain may be 2D planar or 3D. The depth of cut can be absolute 2D only , or incremental 2D and 3D. Used to create precisely located holes. The Drill operation creates holes using points as input geometry. Although it is possible to use endmills in a drilling operation, it is preferable to use drill bits.

With Mastercam, you have complete control over the three crucial elements of multiaxis machining: cut pattern, tool axis control, and collision avoidance. Some highlights of Mastercams multiaxis machining:Rail swarf cutting delivers fine cut control with or without supporting surfaces or solids. HSM can deliver faster turnaround and a superior finish. Mastercam includes HSM toolpaths designed to help you make the most of this powerful technique, even if you dont have a high speed machine.
Mastercam also delivers another powerful way to get the most out of your machines. As every shop owner knows, running an entire job at a single feed rate reduces efficiency. Running the same job at varying optimal feed rates can save time and money, and reduces tool wear.
Our Feed Rate Optimization feature enhances any 2-axis or 3-axis toolpath based on the volume of material being removed and machine tool limitations; more material and the cutter moves slower, less material and the cutter moves faster. Feed Rate Optimization will also automatically ease the tool in and out ofSpecialized toolpaths support fast, efficient 5-axis drilling. Automatically machine flat areas using new time-saving minimum retracts and smooth entry, exit, and cut motion.
High speed area clearance removes bulk material from the inside-out with smooth motion. Multisurface 5-axis roughing and finishing including depth cuts , plunge roughing, flowline machining, and drilling.

Leaves a defined amount of stock on horizontal drive geometry. Sets an extra height used in the ramping motion down from a top profile. Sets the angle of descent for the entry move and determines the pitch. This toolpath does not enter down into the stock, so you do not need to set any entry parameters. The retract distance is the height that the tool moves up to before the next tool pass.
Mastercam measures absolute values from the origin 0,0,0. This determines the final machining depth and the lowest depth that the tool descends into the stock.
In this case, the machining depth will be in the middle of the part because Dynamic Mill uses the entire tool to cut. Your Depth should now be set at Exercise 4: Creating the second Dynamic Mill toolpath You will now create a second Dynamic Mill toolpath using the Rest material option.
In the Toolpaths Manager with the Dynamic Mill toolpath selected, select Toggle display on selected oper- ations. This will hide the display of the first toolpath and keep your graphics view clean while you create another toolpath. Select the geometry shown below as the machining region.
Use the Cplane button to select the entire chain. This enables the page and tells Mastercam to calculate the cutting passes based on the remaining stock.
This calculates the remaining stock from a single operation. This option makes no adjustments to the stock model. Sets the height that the tool rapids to before changing to the plunge rate to enter the part.
Your Depth should be You will notice that the toolpath clears out the top of the part while avoiding the large feature that was selec- ted as the avoidance region. Mastercam Simulator allows you to verify your toolpaths by using solid models to simulate part machining against a selected stock definition.
Verify creates a representation of the surface finish and shows collisions, if any exist. Use Verify to identify and correct program errors before they reach the shop floor. Right-click in the graphics view and select Fit and Isometric from the menu. Mastercam Simulator should match the image shown below.
View the Move List, which displays all pertinent information about the toolpaths being verified. The two Dynamic Mill toolpaths are able to machine the part in the time shown with the given parameters.
The Dynamic Mill toolpaths easily and quickly remove all of the stock on the outside and prepares the part for any other necessary operations. In the next lesson, you will create a Face toolpath to further machine this part. This toolpath can be based on chained geometry or on the current stock model. For this lesson, you will create a Face toolpath on the top of the part from the Dynamic Mill lesson. Exercise 1: Creating the Face toolpath 1.
Open the part file, FaceMill, provided with this tutorial or use your part file created from the Dynamic Mill lesson. If you are using your part from the previous lesson, select Toggle display on selected operations on the Toolpaths Manager. This will hide the two Dynamic Mill toolpaths and keep the graphics view clean.
If necessary, expand the Tool Name column to see the entire tool name. Creates a smooth controlled motion that cuts from the outside to the inside, main- taining a constant load on the tool with minimal entries and exits. Sets the amount of stock to leave on the floors during machining.
Sets the distance between adjacent passes in the toolpath. Sets the height that the tool moves up to before the next tool pass. Sets the height that the tool rapids before changing to the plunge rate to enter the part.
Before clicking OK, you will first preview the toolpath. Previewing toolpaths allows you to view the toolpath before generating it so that you can make adjustments as necessary. Exercise 2: Verifying the toolpaths You now verify the two Dynamic Mill toolpaths created from the previous chapter and the Face toolpath together.
The three Dynamic Mill toolpaths are able to machine the part in the time shown with the given parameters. Mastercam Simulator color-codes each toolpath so that you can distinguish where each toolpath cuts the part. The colors on the part correspond to those on the time bar. Using the Dynamic Mill toolpaths and the Face toolpath, you have quickly cleared the part to prepare it for finishing operations.
In the next lesson, you create two Dynamic Contour toolpaths. Compared to its standard counterpart, the Dynamic Contour toolpath provides much more efficient cutting by using the entire flute of the tool. Exercise 1: Setting up the stock 1.
Open the part file, DynamicContour, provided with this tutorial. Exercise 2: Creating the first Dynamic Contour toolpath 1. In Solid chaining mode, the Chaining dialog box gives you options to manage the chaining of solid entities. The Pick Reference Face dialog box displays. This dialog box allows you to cycle through possible reference faces on a solid until you reach the one you want. Select the Endmill1 Flat filter, and deselect any other filter. This ensures that you are only selecting flat end mill tools.
Offsets the tool to the right or left of the toolpath. Offsets the machining region to ensure the tool does not engage too much material during the first pass of the toolpath when entering stock from the outside.
You are not leaving any stock on the vertical and horizontal surfaces. Both parameters help define the shape of the stock removed by the toolpath. Mastercam calculates the stock to remove along the contour wall by using these parameters. This measures absolute values from the origin 0,0,0. Sets the height that the tool moves up before the next tool pass. Depth determines the final machining depth and the lowest depth that the tool descends into stock.
You will select an edge for this toolpath. Exercise 3: Creating the second Dynamic Contour toolpath 1. The chain will display as shown below.
Reverse the direction if needed, using Reverse on the Chaining dialog box. This ends the chain so that you can start a new one that is not linked to the previous chain. Incremental values are relative to other parameters or chained geometry.
Exercise 4: Analyzing the toolpaths You now analyze the toolpath. Analyze Toolpath allows you to view toolpath properties, such as coordinates, dir- ection, operation number, and other information by hovering over the toolpath.
Analyze Toolpath informs you of the operation number, the feed move, spindle speed, G1 and the line length, and the coolant code.
It also displays the start and end of the toolpath and of the section you are hov- ering over. If there is more than one toolpath displayed at the time, then toolpaths other than the one you are hovering over are dimmed. Continue hovering over areas of both toolpaths.
Once you are satisfied, press [Esc] or Cancel out of the func- tion. Right-click in the graphics view and select Fit and Isometric, if necessary, so that the display matches the image below:. By using two Dynamic Contour toolpaths, the total machining time is approximately one minute. Open the part file, PeelMill, provided with this tutorial.
For this part, no geometry needs to be created. The bounding box will be accepted as it is. Exercise 2: Creating the first Peel Mill toolpath 1. This toggles the translucency of the current model and will help with selection for this first toolpath.
Select the two edges shown below. Use Reverse if necessary to ensure both chains go in the same direction. This adjusts the final tool engagement with the material. Click Top of stock to return to the graphics window to select the top of the stock of the part. The toolpath is copied below the original.
There are now two Peel Mill toolpaths in the Toolpaths Manager. Copy the toolpath once more. You will now have three Peel Mill toolpaths in the Toolpaths Manager. Copying and pasting toolpaths is helpful when you have to do similar cuts on the same part. In the case of these toolpaths, you will have to re-chain the geometry. Exercise 4: Re-chaining the copied Peel Mill operations In this exercise, you will re-chain the geometry for the Peel Mill toolpaths that were copied. Select the chains shown below.
Ensure that the chains are both going in the same direction. You may need to rotate the part or select Translucency on the View tab to select them. By doing this, you only need to select the chains for the toolpath without having to go through creating the entire toolpath again. The second and third Peel Mill toolpaths regenerate using the newly selected chains. All three Peel Mill toolpaths will display as shown below:. Exercise 5: Verifying the toolpaths In this exercise, you will verify all three Peel Mill operations together.
When creating similar toolpaths, copying and pasting saves time. In the next lesson you create two Dynamic OptiRough operations and a stock model operation. In this lesson, you will create two Dynamic OptiRough toolpaths using different cutting strategies, and a stock model operation in order to rough out the part.
Exercise 1: Setting up the stock In this exercise, you will create the stock model that will be used for the first Dynamic OptiRough toolpath. If it is not displayed, select Levels from the View tab to toggle the display.
This will add a small amount of stock at the top of the part. This will create lines and arcs based on the stock boundary. You will then use this geometry to contain the first Dynamic OptiRough toolpath. The stock model displays as a dashed outline in red. The geometry that was created with the Bounding Box also displays.
Exercise 2: Creating the first Dynamic OptiRough toolpath In this exercise, you create the first Dynamic OptiRough toolpath that uses this stock boundary. Use window select or any applicable keyboard shortcuts to select the part body as the drive surfaces. This includes the blue caps, as shown below. Since you are creating a roughing toolpath, enter the following stock to leave amounts on the wall and floor.
Double-click to activate the field. This returns you to the graphics window to select one or more closed chains of curves to limit the tool motion. In the graphics window, select the geometry at the top of the stock boundary. You may need to change to Wireframe mode in the Chaining dialog box. From outside sets the toolpath to machine from outside the containment boundary moving in.
This strategy is best used for machining cores. Select the Endmill3 Bull filter, and deselect any other tool filter. This ensures that you are only selecting bull end mill tools. Mastercam first machines all stepdowns, moving from pocket to pocket. After all stepdowns on a Z-level are machined to completion, Mastercam machines the stepups by next closest, in the safest cut order.
Determines the Z spacing between adjacent cutting passes. Sets the minimum toolpath radius to create in the operation. Specifies a minimum pocket size that Mastercam will create a cut- ting pass for. This helps with problems where Mastercam thinks that a pocket is large enough to accom- modate the tool, but the entry move is so compressed the tool is effectively plunging into the part.
Mastercam 2018 dynamic optirough stock to leave free.How Mastercam OptiRough Can Save You Hours of CNC Programming Time
The stock box is represented by a dashed red rectangular prism. Enter the as-measured dimensions of your stock into the X, Y, Z fields. Default units are inches.
Tick the display checkbox to show stock box in MasterCAM model space. After defining stock dimensions, u sers MUST manually update machining heights to reflect the stock thickness for each operation individually. MasterCAM will not auto-update these values. Inaccurate values cause collisions during verification. A roughing operation is used to remove large amounts of material rapidly and to produce a part geometry close to the desired shape. A roughing operation uses large diameter tools and coarse settings, and should not cut all the way down to the drive surface s , instead leaving a small offset for the finishing operations to clean up afterwards.
When stock thickness exceeds the shoulder length of the tools, the surrounding uncut stock may interfere with toolpaths drawn on the perimeter of the part, causing collisions. In this circumstance, it is necessary to partially clear away the stock outside the part perimeter before proceeding to the finishing operations. The Contour 2D operation may be used for roughing as follows:. Note that the Contour 2D operation is not context-aware.
Nearby parts may be gouged if there are multiple parts being machined from a single stock. The Surface Rough Parallel operation moves the tool in equally spaced parallel passes in the XY plane across the surface, cutting down incrementally in multiple steps. The toolpath can be drawn as One Way best for anisotropic materials with grain direction, slower or Zigzag best for isotropic materials, faster.
Note that all surfaces except stock extents are assigned as Drive surfaces in a typical MasterCAM file. A finishing operation follows roughing and is used to achieve the final geometry and surface finish. Most MasterCAM files need at least one and frequently several separate finishing operations to produce an acceptable part.
Finishing operations clean up the extra material purposefully left behind by the roughing operation. Finishing operations must be employed on a case-by-case basis, as the utility of each operation type varies from one file and geometry to the next. See reference pages linked above for a detailed explanation of concepts and usage that are common across all operation types. Commonly used finishing operations are listed below.
Users must review them and determine which operations are appropriate for their geometry. The Surface Finish Parallel operation moves the tool in equally spaced parallel passes in the XY plane across the surface.
The toolpath can be drawn in any angle relative to the XY origin. This operation is often used with varying stepovers and machining angles to create surface patterns on site models. Used primarily to clear material from vertical or steep features. The Surface Finish Contour operation cuts geometry by offsetting toolpaths away from the drive surface at incremental heights.
As sloped geometry becomes steeper, the toolpaths get closer together; as that geometry becomes more shallow, the toolpaths are spaced farther apart. This operation is often paired with a flat endmill for use on vertical building faces. Note that the horizontal surface building top is the Drive surface. Used primarily to clear flat areas, such as stepped terrain or building tops. The Surface Finish Shallow operation cuts geometry whose slope angle does not exceed a threshold users can set maximum.
This operation is often paired with a flat endmill for use on stepped topography and building tops. Users can dramatically reduce machining time by strategically using larger diameter tools to cut open areas, while targeting small diameter tools to narrower channels.
Used primarily to clear sloped areas, such as rolling topography. The Surface Finish Constant Scallop operation cuts geometry by dynamically adjusting stepover users can set maximum as a function of the slope angle for any given point along the drive surface. This method maintains a uniform scallop height across variable relief, and thus uniform smoothness. This operation is often paired with a ball endmill for use on rolling topography and gentle slopes.
Used to cut flat-bottomed holes, such as building footprints. The Pocket operation removes material from within a closed chain, creating recesses with flat bottoms. Note that t he Pocket operation includes its own internal Roughing and Finishing stages within the parameters. This operation is often paired with a flat endmill to cut building footprints. Pockets are preferred over Surface Finish Shallow for cutting deep, flat-bottomed recesses due to their incorporation of incremental depth cuts.
Used to trace linear features, such as final perimeter cut-out. The Contour operation cuts along a chain or series of chains. The cut may be compensated to the left or right of the chain s , or on center if compensation is turned off.
The chain may be 2D planar or 3D. The depth of cut can be absolute 2D only , or incremental 2D and 3D. Used to create precisely located holes. The Drill operation creates holes using points as input geometry. Although it is possible to use endmills in a drilling operation, it is preferable to use drill bits. Selecting a Stepover. In most cases, select TOP as work coordinate system, tool plane, and construction plane. When machining the underside of a two-sided job flip milling , select FLIP as work coordinate system, tool plane, and construction plane.
Select largest diameter flat upcut endmill to remove material quickly. Harder materials require shorter tools. Special tools are available for roughing solid wood, plywood, and mdf.
Input a positive offset for both Drive and Check surfaces. Default is 0. Select One Way if stock material is non-uniform wood, other materials with grain , or Zigzag if stock material is uniform foam, plastics, mdf. Value should not exceed flute length of tool, and must be appropriate for stock material. Harder materials require smaller stepdown. Value should not exceed tool diameter, and must be appropriate for stock material. Click Select under Avoidance regions. Avoidance regions are regions that you want to avoid during machin- ing.
In this case, you want to avoid the part itself and clear out the area between the stock boundary and the part. To do this, you will need to activate another level.
This will display the geometry we need to select. The geometry is a silhouette of the part. This allows you to machine around the part and clear out the stock, but without cutting into the part.
Before you accept these chains in the Chain Options dialog box, you will first preview them to see if these are the chains you want. Mastercam displays your material in the red and black crosshatch, the motion region as blue, and the tool con- tainment as yellow. By using Preview chains, you can determine if that is what you want from the toolpath before entering any parameters. You can change these colors by selecting the Color button. These options are also available on the Toolpath Type page.
Select None to remove all filters, and then select EndMill3 Bull. This ensures that you are only showing Bull end mills tools. If necessary, expand the Tool Name column to view the entire tool name. Sets the distance between cutting passes in the X and Y axes.
Mastercam uses this radius in combination with the Micro lift dis- tance and Back feed rate parameters to calculate 3D arc moves between cutting passes. Sets the distance the tool lifts off the part on back moves. Controls the speed of the back feed movement of the tool. Directs the toolpath to start at the most recently machined material when cutting. Leaves a defined amount of stock on the vertical drive geometry. Leaves a defined amount of stock on horizontal drive geometry. Sets an extra height used in the ramping motion down from a top profile.
Sets the angle of descent for the entry move and determines the pitch. This toolpath does not enter down into the stock, so you do not need to set any entry parameters. The retract distance is the height that the tool moves up to before the next tool pass. Mastercam measures absolute values from the origin 0,0,0. This determines the final machining depth and the lowest depth that the tool descends into the stock.
In this case, the machining depth will be in the middle of the part because Dynamic Mill uses the entire tool to cut. Your Depth should now be set at Exercise 4: Creating the second Dynamic Mill toolpath You will now create a second Dynamic Mill toolpath using the Rest material option. In the Toolpaths Manager with the Dynamic Mill toolpath selected, select Toggle display on selected oper- ations. This will hide the display of the first toolpath and keep your graphics view clean while you create another toolpath.

Reverse the direction if needed, using Reverse on the Chaining dialog box. This ends the chain so that you can start a new one that is not linked to the previous chain. Incremental values are relative to other parameters or chained geometry.
Exercise 4: Analyzing the toolpaths You now analyze the toolpath. Analyze Toolpath allows you to view toolpath properties, such as coordinates, dir- ection, operation number, and other information by hovering over the toolpath. Analyze Toolpath informs you of the operation number, the feed move, spindle speed, G1 and the line length, and the coolant code.
It also displays the start and end of the toolpath and of the section you are hov- ering over. If there is more than one toolpath displayed at the time, then toolpaths other than the one you are hovering over are dimmed.
Continue hovering over areas of both toolpaths. Once you are satisfied, press [Esc] or Cancel out of the func- tion. Right-click in the graphics view and select Fit and Isometric, if necessary, so that the display matches the image below:. By using two Dynamic Contour toolpaths, the total machining time is approximately one minute.
Open the part file, PeelMill, provided with this tutorial. For this part, no geometry needs to be created. The bounding box will be accepted as it is. Exercise 2: Creating the first Peel Mill toolpath 1. This toggles the translucency of the current model and will help with selection for this first toolpath.
Select the two edges shown below. Use Reverse if necessary to ensure both chains go in the same direction. This adjusts the final tool engagement with the material.
Click Top of stock to return to the graphics window to select the top of the stock of the part. The toolpath is copied below the original. There are now two Peel Mill toolpaths in the Toolpaths Manager. Copy the toolpath once more. You will now have three Peel Mill toolpaths in the Toolpaths Manager.
Copying and pasting toolpaths is helpful when you have to do similar cuts on the same part. In the case of these toolpaths, you will have to re-chain the geometry. Exercise 4: Re-chaining the copied Peel Mill operations In this exercise, you will re-chain the geometry for the Peel Mill toolpaths that were copied. Select the chains shown below. Ensure that the chains are both going in the same direction.
You may need to rotate the part or select Translucency on the View tab to select them. By doing this, you only need to select the chains for the toolpath without having to go through creating the entire toolpath again. The second and third Peel Mill toolpaths regenerate using the newly selected chains.
All three Peel Mill toolpaths will display as shown below:. Exercise 5: Verifying the toolpaths In this exercise, you will verify all three Peel Mill operations together. When creating similar toolpaths, copying and pasting saves time. In the next lesson you create two Dynamic OptiRough operations and a stock model operation. In this lesson, you will create two Dynamic OptiRough toolpaths using different cutting strategies, and a stock model operation in order to rough out the part.
Exercise 1: Setting up the stock In this exercise, you will create the stock model that will be used for the first Dynamic OptiRough toolpath. If it is not displayed, select Levels from the View tab to toggle the display. This will add a small amount of stock at the top of the part. This will create lines and arcs based on the stock boundary.
You will then use this geometry to contain the first Dynamic OptiRough toolpath. The stock model displays as a dashed outline in red. The geometry that was created with the Bounding Box also displays. Exercise 2: Creating the first Dynamic OptiRough toolpath In this exercise, you create the first Dynamic OptiRough toolpath that uses this stock boundary. Use window select or any applicable keyboard shortcuts to select the part body as the drive surfaces.
This includes the blue caps, as shown below. Since you are creating a roughing toolpath, enter the following stock to leave amounts on the wall and floor.
Double-click to activate the field. This returns you to the graphics window to select one or more closed chains of curves to limit the tool motion.
In the graphics window, select the geometry at the top of the stock boundary. You may need to change to Wireframe mode in the Chaining dialog box. From outside sets the toolpath to machine from outside the containment boundary moving in.
This strategy is best used for machining cores. Select the Endmill3 Bull filter, and deselect any other tool filter. This ensures that you are only selecting bull end mill tools. Mastercam first machines all stepdowns, moving from pocket to pocket.
After all stepdowns on a Z-level are machined to completion, Mastercam machines the stepups by next closest, in the safest cut order. Determines the Z spacing between adjacent cutting passes. Sets the minimum toolpath radius to create in the operation. Specifies a minimum pocket size that Mastercam will create a cut- ting pass for. This helps with problems where Mastercam thinks that a pocket is large enough to accom- modate the tool, but the entry move is so compressed the tool is effectively plunging into the part.
Creates high-speed loops into and out of each retract move. Outputs the rapid move between passes as a feed rate move instead of a rapid move. This helps when the tool needs to make many irregular moves per pass to jump between different areas of the part. Exercise 3: Creating the Stock Model operation You now create a Stock Model operation that uses the previous operation as its source. This stock model will be used in the second Dynamic OptiRough toolpath to remove any remaining stock.
This will only display the toolpath you have selected. It will also clean up the graphics view when making modi- fications to the part or creating another toolpath. Naming your stock model based on which operation it is using is helpful, especially when you have a part with multiple stock model operations.
Stock Setup copies the values defined in the Machine Group Properties dialog box to corresponding fields in the Stock Definition page. The values are not associative. The stock model is generated by running the selected operation against the parameters on the Stock Defin- ition page. Exercise 4: Creating the second Dynamic OptiRough toolpath You now create the second Dynamic OptiRough toolpath that uses the stock model you created in the previous exer- cise. Select Toggle display on selected operations.
This hides all selected toolpaths to keep the graphics window clean. In the Levels Manager, turn off the display of the Caps level and turn on the Stock geometry level to make it easier to select the drive surfaces. This sets the outer edge of the tool to be bound to the containment boundary.
This option adjusts the inside or outside tool containment boundary. When you enable this page, Mastercam calculates the cutting passes based on the remaining stock.
This option is used in conjunction with Ignore small cusps. Mastercam will output cuts that engage large amounts of material. Mastercam moves to the closest cut from its last position on the previous cut.
Adds retracts to avoid intersecting boundaries a gouge boundary, or a boundary of material yet to be milled. Select Toggle display on selected operations to display toolpaths again, and select the second Dynamic OptiRough toolpath to view the newly created toolpath. Exercise 5: Verifying the stock model and toolpaths In this exercise, you use Mastercam Simulator to verify your toolpaths and stock model. Verifying your toolpaths allows you to use solid models to simulate part machining against the selected stock definition.
Dynamic Milling creates an active toolpath that delivers more consistent cutting conditions and allows use of the entire tool flute length, while reducing machining time.
Feature Based Machining FBM automatically programs a solid models pockets, contours, and drilling routines, including new slug cutting and hole mapping. Standard pocketing styles include zigzag, one way, true spiral, constant overlap spiral, morph pocketing, and open pocketing.
Suite of entry methods including plunge, helical, ramp, profile, medial, or custom including trochoidal entries. Contour and pocket remachining use smaller tools to automatically clean out material left from previous operations.
Region Chaining delivers a fast and easy way to adjust your 2D high speed machining areas. Ability to click and drag a machining start point to anywhere on your model. Automated slot, circle, and thread milling. Controlled engagement facing removes stock using a consistent tool load. Automatic identification and pre-drilling of multiple operations at their plunge points. Automatic drilling and countersink depth calculation. Cut multiple surfaces, solid models, or a combination of both.
High speed OptiRough removes large amounts of material quickly. The tool takes an aggressive depth cut, followed by a series of quick up-cuts, then repeats the process at the next depth. High Speed OptiRest uses Mastercams new stock model to identify and efficiently machine areas that need to be roughed with a smaller tool. Constant scallop machining maintains a consistent finish on sloped and flat surfaces alike by using a consistent 3D stepover.
Full check surface support. Smart hybrid finishing and hybrid leftover machining each create a single toolpath that changes cut methods as the slope of the model changes. Constant-Z rest milling remachining identifies and machines areas and critical depths that need to be cut with a smaller tool. Pencil tracing walks a tool along the intersection of surfaces to clean out hard-to-reach areas.
You can perform single or multiple passes for precision cleanup. Go to www. Hybrid finishing intelligently blends two efficient cutting techniques in one toolpath. Dynamic Milling creates an active toolpath that delivers more consistent cutting conditions and allows use of the entire tool flute length.
Feature Based Machining makes it significantly easier to machine prismatic solids by automating the programming process. Multiaxis MachiningMultiaxis machining can dramatically increase a shops competitiveness.
Mastercam offers a wide range of multiaxis machining strategies. With Mastercam, you have complete control over the three crucial elements of multiaxis machining: cut pattern, tool axis control, and collision avoidance. Some highlights of Mastercams multiaxis machining:Rail swarf cutting delivers fine cut control with or without supporting surfaces or solids.
HSM can deliver faster turnaround and a superior finish. Mastercam includes HSM toolpaths designed to help you make the most of this powerful technique, even if you dont have a high speed machine. Mastercam also delivers another powerful way to get the most out of your machines. As every shop owner knows, running an entire job at a single feed rate reduces efficiency. Running the same job at varying optimal feed rates can save time and money, and reduces tool wear.
