Counter Bore Tutorial

The counter bore example follows the same procedure as the other hole making features. The only difference is in the geometry selection. Follow this lesson to create a Counter Bore feature, toolpath and NC program.

• Click File, Open

• Select HoleExample.SLDPRT (C:\BobCAM Data\BobCAM V2\Examples\HoleExample.SLDPRT)

You must assign a Coordinate System to the Machine Setup.

To insert a Counter Bore Feature:

• In the BobCAM CAM tree, right-click (click the right mouse button) Milling Stock, click Drill to open the Hole Wizard

• Click Counter Bore Hole, Next to move to the Geometry Selection page

To associate the geometry with the feature:

• Click Select Geometry

• Click the two cylindrical faces of each of the three counter bore holes as shown next

• Click , Next, Finish to exit the Hole Wizard

NOTE: After inserting a Counter Bore feature, you can also select the feature geometry by right-clicking Geometry and clicking Re/Select from the CAM tree.

To compute the toolpath:

• In the BobCAM CAM tree, under Feature Counter Bore Hole, right-click Counter Bore Hole, click Compute Toolpath

The result should look like the following image

To post the NC program:

• In the CAM tree, under CAM Part, right-click Milling Tools

• Click Post, the NC program is displayed in the Posting tab

This concludes the basic process of creating a Counter Bore feature, toolpath and NC program. For more information on selection options, view Counter Bore Selection.
