What is a Roughing Operation? – Mastercam 2018 change units free

 

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. During simulation playback, areas of the stock involved in a collision will be colored dark red. The type of collision can be identified in the Collision Report. An immediate collision upon simulating an operation Flute Length – In Progress Stock is typically the result of incorrectly defined Machining Heights within that operation. MasterCAM Simulator provides an estimate of total run time for selected operations based on specified feed rates, stepover, stepdown, etc.

This estimate is displayed in the Move List panel on the right. After playing through the simulation, check “Elapsed Time” for the time estimate. Often this estimate is too low by a factor of 2, so as a rule of thumb, double the MasterCAM Simulator time estimate when making a CNC appointment reservation. Fab Lab Store.

Detailed Description of Key Parameters. Tool Selection Select largest diameter flat upcut endmill to remove material quickly. Machining Heights Input values appropriate for stock thickness. Stepover Value should not exceed tool diameter, and must be appropriate for stock material. Machining Angle Change value to match grain direction of stock if cutting method is One Way and stock material is non-uniform. Tool Selection Select largest diameter flat endmill that can maneuver completely around input geometry while producing desired resolution.

Tool Selection Select largest diameter flat upcut endmill that can maneuver completely across input geometry while producing desired resolution. You can work with the full interface that gives you access to all the available parameters and options. You can also choose from a number of simplified interfaces that have been customized for specific applications and machining strategies.

These toolpaths work on surfaces. Solid selection is available for most advanced multiaxis toolpath strategies, with the following exceptions: toolpaths that require the selection of a defined edge solid edge and toolpaths that require the selection of only a single surface solid face.

This is useful for engraving and similar applications. Projection curves should lie on or above the surface, within the maximum projection distance. Toolpath Type The Toolpath Type page allows you to establish the type of multiaxis toolpath to create. The toolpath type controls the options available as you proceed down the tree structure.

The Toolpath Type page allows you to select between the two toolpath groups, Pattern or Applications. You can then choose one of the toolpaths inside of that group. Angle Step Discover other Mastercam Training Solutions at www.

While there, be sure to join the conversation! Wireframe Enhancements Listed below are enhancements made to Wireframe functions. These new features will help in the creation of more accurate containment boundaries. Ignore shared edges off Ignored shared edges on Only outside loops Curve All Edges now allows you to create curves from only exterior edges of a solid and ignores the inner edges when you select Only outside loops.

It is only active when solid faces are selected. Previously, these functions only supported creating geometry in 3D mode. By supporting 2D geometry creation, geometry created from the selected edge can be projected to the current Cplane and Z depth, instead of requiring you to use another function, such as Project.

Create Letters is now in a function panel, allowing you to work simultaneously within the graphics window. This also means that the letters are now live entities, so when you choose a new font, reposition, or edit the text it now shows the results in the graphics window.

Use Edit Spline to refine and prepare splines. You can move, rotate, or lengthen the tangent vector or move the control point. For more control and a finer adjustment of the curve, you can add or remove node points, or increase the number of control points.

Helix and Spiral Helix and Spiral function panels now include locks for specific fields. The fields you can lock are Revolutions, Height, Pitch for helix creation, and Initial Vertical Pitch for spiral creation. Locking a field does not prevent you from changing that value, it simply establishes which field is constant and which two are calculated.

Select this option to create a line by selecting two points. The first point selected will be the midpoint and the second point will define one end while the other end of the line is a mirror in the opposite distance and angle.

Modify at Intersection allows you to trim, break, or create points with lines, arcs, and splines where they intersect with surfaces, solid bodies, solid faces, and solid sheet bodies.

This is particularly useful when modeling or prepping for Multiaxis toolpaths. Select Modify at Intersection, and then use any selection method to select the wireframe geometry that you want to edit.

After selecting the wireframe, select an intersecting surface, face, or solid body to display the function panel. When trimming geometry, Mastercam keeps the wireframe on the Normal side of the surface or solid by default. To change this, click Reselect.

Improved Inch and Metric Support Mastercam now supports mixing inch and metric tools and holders when building tool assemblies in Mill. You can use metric tools in inch part files and inch tools in metric part files.

This includes proper tool compensation and scaling in Backplot and Verify. Note: This does not support scaling operation parameters when changing system units. This launches another dialog box to allow you to select the tools you wish to import. The cloud icon in the second column indicates that the associated tool assembly has not been validated. If the tool assembly passes Mastercam’s validation tests, you will see a green checkmark indicating that it can now be saved.

If Mastercam detects problems with the tool, an icon will display indicating the severity of the problem. A red X indicates that there is a critical issue that must be resolved first. A yellow exclamation mark indicates a non-critical warning. Use the hyperlink in the description field to review or edit the tool in question. The importer does not connect to a server process; instead, you import ZIP files containing your tool assemblies using the Open button.

Similar to importing with CoroPlus see “Importing with CoroPlus” on page 80 , all assemblies must be validated before they can be used in Mastercam. This includes improvements to the 2D, 3D, and Multiaxis suite of toolpaths. General Enhancements Listed below are enhancements that apply to Mill toolpaths in general, not just 2D or 3D toolpaths. Drill point sorting Sort by name has been added to the Drill Point Manager right-click menu. This allows you to reset the sort order to the original selection order or in the order you have named the drill points.

When the cutter moves through outside arcs, the perimeter of the cutter is moving through the material slower than the center of the tool, which results in a decreased chipload on the tool. Contour The following enhancements apply to the standard 2D Contour toolpath.

Chamfer tool offset In previous versions, you could only modify the Tip offset when chamfer milling, allowing you to control how far past the bottom chamfer rail the tip of the chamfer tool extends.

Top offset places the full diameter of the chamfer tool at a specified distance above the top rail of the chamfer. Bottom offset amount ensures the tip of the tool clears the bottom of the chamfer. Width has also been renamed to Chamfer width. You can also now enter 0. This allows you to chain the top or bottom rail of an existing chamfer and place the chamfer where you desire using the top or bottom offset value.

Multi pass order In Mastercam , multi passes were only ordered By contour, meaning it completed one chain before moving on to the next.

In , you can now choose By contour or By pass on the Multi Passes page. By pass orders the multi passes by pass number. It will run the first multi pass on all contours, then the second multi pass on all contours, and so on.

Rough pass cut direction You can now control the cut direction of rough passes on the Multi Passes page. Select either One way or Zigzag. One way causes the rough multi 87 What’s New in Mastercam — Mill Enhancements passes to behave as they did in past versions. Zigzag will alternate the cut direction between climb and conventional. Both options respect the Keep tool down option. These options allow you to order your cuts from top to bottom or from bottom to top.

By contour and By region machine each machining region to completion before moving to the next. In previous versions, you could only machine finish passes at all depths or at the final depth. Now you can add or remove finish cuts, based on the number of rough depth cuts specified on the Depth Cuts page. Add between creates a finish pass at all depth cuts and adds a specified amount of passes between depth cuts. For example, when set to 2, Mastercam adds two evenly spaced passes between depth cuts.

In the image 89 What’s New in Mastercam — Mill Enhancements below, the red lines represent depth cuts and the blue lines represent multipass finish passes. Per number of adds a finish pass only at every specified depth cut. A multipass finish pass is always added to the last depth cut. When set to 2, Mastercam adds a finish pass only at every second depth cut, depicted by the blue and red lines together below.

After you save the file, it will appear in a text-editing window so you can review it or make changes, as shown in the following picture. Post processors are machine- and control-specific. When you installed Mastercam, you selected a default post processor.

The current post processor is listed here. If you need to, you can select a different one by choosing Change Post. Close the NC program window to return to Mastercam.

Setting the default tool library The remaining exercises in this tutorial will use tools from the MetricST In this procedure, you will make this the default tool library, so that you do not have to keep selecting it. Choose Main Menu, Screen, Configure.

Choose the Files tab. Choose Tool library in the File usage list. TL9 appears in the File name field as shown in the following picture. If it doesn’t, choose the File button and select it. Choose Save As to save the setting to the configuration file. Choose Save. Choose Yes when asked to overwrite the current file.

You’ve now seen all the major stages of creating a part and an operation to machine it. In the next chapter, you will use the simple operation you created in this chapter as a building block for more sophisticated operations.

You will create the following new operations: Finishing and multi-pass roughing operations A chamfering operation A mirrored copy of the operation The part used in this chapter is the same one that you saved at the end of Chapter 3.

If you did not complete Chapter 3, use the file new elbow- mm. Exercise 1 — Creating roughing and finishing passes The 2D contour toolpath you created in the previous chapter only has a single cutting pass. You decide that it takes off too much stock for a single pass, so you decide to rough out the part in multiple passes with a larger tool. You will complete the part with a separate finishing operation.

In this exercise, you will use the following skills: Copying operations Creating multiple passes Creating finishing operations Changing tools and feed rates Copying operations To create the separate operations for roughing and finishing with the minimum number of steps, you will copy the current 2D contour operation and then edit the parameters for each copy. If necessary, open the part file you saved at the end of Chapter 3. If you did not complete Chapter 3, choose File, Get from the menu, and open the file new elbow-mm.

Right-click on the Contour folder icon and drag it below the NCI icon. Release the mouse button and choose Copy after. A copy of the operation appears as shown in the following picture. Click on the name of the first operation until it highlights for editing, and type in a new name: Rough 6. Repeat for the second operation and type the new name: Finish. The operations should look like the following picture. Setting the roughing parameters To make the first operation a true roughing operation, you will select a bigger tool for it and specify multiple passes.

Choose the Parameters icon for the Rough operation. Since this is a roughing pass, you should leave some stock for the finish operation. Enter 1 in the XY stock to leave field.

Your contour parameters should match the following picture. Select the Multi passes check box and button. Enter 2 for the Number of Roughing passes and select Keep tool down. The rest of the values should match the following picture. Enter an Overlap of 5. This means that the entry and exit arcs will overlap by this distance. Choose the button to copy the settings to the Exit section.

Your values should match the following picture. Setting the finish parameters Since the second operation will be a finish operation, you will keep the original tool, but will use a slower feed rate.

Choose the Parameters icon for the Finish operation. Enter a Feed rate of Enter an Overlap value of 5. Make sure the other values match the following picture. Choose OK twice to return to the Operations Manager.

Choose Select All. Choose Regen Path to regenerate both operations with the new parameters. The new toolpaths should look like the following picture. Make sure both operations are still selected as shown in the following picture. Set the Verify option to Y. Press [S] to step through the toolpath. Notice how the stock is removed after each pass, and how the finish tool cleans out the areas that the roughing tool cannot reach.

The following picture shows you a snapshot midway through the final finish operation. You can see the stock left by the roughing operation and how the finish operation is cutting right to the blueprint dimension. Tip: The blue check marks indicate which operations are selected. Press OK when the backplot is finished. Choose Main Menu, File, Save and save the file in your working folder as elbow2.

Exercise 2 — Creating a contour chamfer Next, you would like to add a chamfer to the contour. Mastercam has contour toolpath options that let you easily create a chamfer by specifying some simple dimensions. You will create a separate operation for the chamfer that uses a chamfer tool. You will learn the following skills: Creating 2D chamfer operations Using the Verify feature to preview stock removal Creating the chamfer operation You will create the chamfer operation in the same way that you created the finishing operation in the previous exercise, by copying an existing operation and editing its parameters.

Make a copy of the Finish operation and name the copy Chamfer. See page 45 if you don’t remember how to do this. Choose the Parameters icon for the new Chamfer operation. Select the 10 mm HSS chamfer mill from the tool library. In the Contour type drop-down list, select 2D chamfer. Choose the Chamfer button. Enter 1 for the Width, and 2. Your selections should match the following picture. Choose OK to return to the Contour parameters dialog box. Enter 0. The actual cutting depth achieved by the chamfer mill is determined by the width and tip offset you entered in step 9.

Your contour settings should match the following picture. Choose OK to return to the Operations Manager. Choose Regen Path to create the toolpath. Using the Verify feature to preview stock removal In previous exercises, you used the Backplot function to preview toolpath motion. In this exercise, you will use the Verify function in the Operations Manager instead.

This function gives you a better picture of the 3D part. While inside the Operations Manager, choose Select All so you can verify all the operations. Choose Verify. Choose the button to set the Verify configuration. Enter 0 for the Z—Max point. Choose the button. Choose the button on the Verify toolbar to end the Verify session and return to the Operations Manager.

Exercise 3 — Mirroring the part and toolpath You are required to manufacture both left-hand and right-hand versions of the part. You can do this by mirroring the part and toolpath. This lets you maintain the original toolpath parameters and machining direction for all the operations, ensuring that the duplicated part has the identical finish and size as the original.

In this exercise, you will learn the following skills: Creating mirror images of parts and toolpaths Re-ordering operations in the Operations Manager for greater machining efficiency Mirroring the part 1.

Press the [Page Down] key several times to zoom out from the part. Right-click anywhere in the graphics window and choose Dynamic Pan from the menu. Click and drag to the right until the part is at the right edge of the screen. Click again to exit dynamic panning. Press [F9] to display the coordinate axes. Choose Toolpath Group 1. This selects all the operations. Choose Type—Mirror. Choose Create new operations and geometry.

Make sure your other selections should match the following picture. Choose the Mirror tab. Choose Reverse toolpath. The original toolpath used climb milling; selecting Reverse toolpath means that the mirrored part will also use climb milling, so the finish on both parts will match. The Mirror tab should match the following picture. The part and toolpaths should look like the following picture.

The way the operations are ordered now, Mastercam will rough the first part, then finish and chamfer it before roughing the second part, resulting in unnecessary tool changes. In this procedure, you will rearrange the operations so that the roughing, finishing, and chamfering operations are grouped to minimize tool changes. You can see the new operations 4, 5, and 6. Click and drag the corner of the Operations Manager window as shown in the preceding picture to make it larger, so you can see all the operations.

Click on the second rough operation Operation 4 and drag it on top of the first rough operation. Click on the second finish operation and drag it on top of the first finish operation. Your operations should be in the following order. Choose Select All, Backplot. Choose Run. You should see the operations machined in the proper order. When the backplot is finished, close the Operations Manager and save the file. In this chapter, you saw how to mirror parts and toolpaths.

In the next chapter, you’ll learn techniques for rotating geometry and operations around a center point so you can easily draw and machine circular parts. After you create the part, you will learn how to rotate toolpaths as well. Exercise 1 — Creating the geometry In this exercise, you will design a wheel with three symmetrical slots as shown in the following blueprint. You will use the following skills: Creating arcs, tangent arcs, and lines Rotating geometry Trimming geometry If necessary, create a new file.

Enter for the diameter. Press [O] to select the origin for the center point. Note: Press the letter “O,” not zero. Enter 40 for the diameter of the inner circle.

Press [O] again to select the origin for the center point. Press [Esc] to exit the Create Arc function. Right-click anywhere in the graphics window and choose Fit screen from the menu. Creating construction lines for the slot To rough out the slot, begin by defining the vertical edges, then rotating to the proper position.

Select at position 1 then at position 2 these are only approximate positions to draw the construction guide. Enter 10 for the X coordinate of the line. Create a second vertical line by selecting near positions 1 and 2 again. Enter —10 for the X coordinate of the line. Next, you will rotate one of the lines to form the other edge of a slot. Select the left line. Choose Done, Origin. Choose Operation—Copy. Enter a Rotation angle of The line should rotate as shown in the following picture.

Creating the arcs for the slot outline Create the inner and outer curves along with the fillet arcs for one of the slots. Press [O] to select the origin as the center point. Type in the radius of the outer arc: 80 4. Click near positions 1 and 2 in the following picture to locate the approximate starting and ending angles of the outer arc. Note: Mastercam measures all arcs in a counterclockwise direction. To create the inner arc, type [O] again to locate its center point at the origin.

Enter its radius: 40 7. Click near positions 3 and 4 in the previous picture to locate the arc’s endpoints. Now create 12 mm fillets at the four corners of the slot. Enter 12 for the radius. Click on the positions shown in the following picture in order.

Completing the first slot To complete the first slot, you need to create the flat edge on the outside radius. First you will create the horizontal line. Then you will rotate it into position and create the arcs that connect it to the slot.

Enter the coordinates for the first endpoint: — Enter the coordinates for the second endpoint: The line should look like the following picture. Select the horizontal line you just created. Choose Operation—Move. Enter a Rotation angle of — The line should rotate into position as shown in the following picture. Zoom in on the new line. Right-click anywhere in the graphics window and choose Zoom window.

Click once near position 1 and then near position 2.
