TUTORIAL #31 OVERVIEW OF STEPS TAKEN TO CREATE THE FINAL PART:

OVERVIEW OF STEPS TAKEN TO CREATE THE FINAL PART:

From Drawing to CAD Model:The student should examine the drawing on the following page to understand what part is being created in the tutorial.From the drawing we can decide how to go about creating the geometry in Mastercam.

Create the 3D CAD Model used to generate Toolpaths from:The student will create the wireframe needed to create the surfaces.Surface creation commands such as net surface, lofted surface, flat boundary surface and solid revolved will be used.

Create the necessary Toolpaths to machine the part:The student will create a solid to be used as the stock model. Other stock models will be created to check the finish toolpaths. A Surface High Speed Rest Roughing toolpath will be created to rough out the part.A Surface High Speed Radial toolpath will be created to finish the part.A Surface Finish Blend toolpath will be created to machine closer to the sharp edges of the part.A Transform Rotate toolpath will be used to rotate the blend surface to complete the part.

Backplot and Verify the file:The Backplot will be used to simulate a step by step process of the tool’s movements.The Verify will be used to watch a tool machine the part out of a solid model.

Post Process the file to generate the G-code:The Student will then post process the file to obtain an NC file containing the necessary code for the machine.

This tutorial takes approximately two hours to complete.

TUTORIAL #31 CREATE THE SOLID TO BE USED AS STOCK

STEP 14: CREATE THE SOLID TO BE USED AS STOCK

In this step you will learn how to create on a different level a solid that will be used to define the stock. Unlike wireframe models, which are a collection of curves, and surface models, which are a collection of surfaces, a solid model is a single entity, regardless of its complexity.

Step Preview:

14.1 Create the solid body by extruding in both directions along a distance of 25.5mm

Solids

Extrude. [Select chain(s) to be extruded]: Select the arc with the diameter 102.0mm as shown.

STEP 16: SELECT THE MACHINE AND SET UP THE STOCK

In Mastercam, you select a Machine Definition before creating any toolpaths. The Machine Definition is a model of your machine tool's capabilities and features and acts like a template for setting up machining jobs. The machine definition ties together three main components: the schematic model of your machine tool’s components, the control definition that models your control unit’s capabilities and the post processor that will generate the required machine code (G-code). For a Mill Level 3 exercise (3D toolpaths) we need just a basic machine definition.

Step Preview:

19.3 Setting the Toolpath Type

Toolpath Type page allows you to change the existing toolpath to a different type. Mastercam updates the parameter pages so that you only see settings for the toolpath type that you selected. You can also change or reselect the drive surfaces, check surfaces, and the tool containment boundaries.



Figure: 19.3.1

NOTE: The High Speed toolpaths have three distinct areas: Tree view, Page and Quick View Settings as shown in Figure: 19.3.1.



From the Toolpath Type make sure that Roughing and Rest Roughing are selected as shown.



19.4 Setting the Tool page

Tool page allows you to select the tool and enter feeds and speeds and configure automatic tool inspection.

From the Tree View Area, select Tool. To select the tool, click on Select library tool button.

Click on the Filter button to search for a specific tool within a tool library.

From the Tool List Filter, select the Bull Endmill icon, and in the Tool Diameter area select Equal and enter the 12.0 as shown.



Make sure that all the other settings are as shown in the screenshot above, and then select the OK button to

exit. From the Tool Selection list select the 12.0mm Bull Endmill with the corner radius of 2.0mm.

Select the OK button to exit from the Tool Selection dialog box. Add a comment in the Comment area to identify the toolpath in the Toolpath Manager and also in the NC file.

The Tool page should look as shown in Figure: 19.4.1.

Figure: 19.4.1

NOTE: The feeds and spindle speed are based on the tool definition. You can overwrite them with the feeds and speed that you want to use. If you click on the tool from the list the feedrates and the spindle speed will be updated to the original values. You can lock them in the Settings, Configuration, Toolpaths page by enabling Lock Feedrates.



19.5 Set the parameters in the Cut parameters page

In this page you can set the Cutting method, configure the Z spacing (Stepdown) and the XY spacing (XY stepover) and the Corner rounding. You can also set the tool containment options.

From the Tree View Area, select the Cut parameters page and change the parameters as shown.

Stepdown value sets a constant Z spacing between cutting passes.

Add cuts feature allows you to insert additional cutting passes in areas of your part where the profile is close to flat.

Corner rounding is used to round the corners of the toolpath. This lets the machine tool maintain a higher feed rate and reduces wear on the cutter.

Max radius limits the size of the arcs Mastercam creates to round the corners.

Profile tolerance defines the variance between the toolpath created with corner rounding and the original toolpath.

Offset tolerance defines the tolerance applied to all of the toolpath's inner passes.

XY stepover settings allows you to configure the spacing between the passes at the same Z.

Stock to leave on drive surfaces lets you enter separate values for the wall and floor surfaces. Note that the stock to leave on walls must be greater than or equal to the stock left on the floor.

Keep tool down prevents the tool from retracting if the distance between the end of one pass and the start of the next pass is less than the specified settings.



19.6 Set Rest Material page

Rest Material page allows you to to define how Mastercam calculates the stock model for a surface high speed toolpath. The stock model defines the amount of stock to be machined by the toolpath. You can choose between one or more source operations from the current part, the diameter of the roughing tool or an external CAD file such as an STL file.

From the Tree View Area, select the Rest Material page and select One other operation and leave the Use remaining stock as computed enabled as shown in Figure: 19.6.1.

Figure: 19.6.1



19.7 Set the Transitions page

Transitions page allows you to configure the entry move that the tool will make as it transitions to new Z levels. You can choose to create either a ramp entry, or helical entry move. If the profile is too small to create a helix of this size, Mastercam will create a ramp move instead.
