Creating the bounding box.
Creating an offset surface.
The Student will create a 3 dimensional milling toolpath consisting of:
Roughing the cavity using surface high speed area mill toolpath.
Finishing the cavity using surface finish contour toolpath.
Finishing the fillets using surface finish leftover.
Creating two 2D pockets toolpaths to be used in surface finish project.
Using finish project toolpaths to machine the raised letters.
The Student will check the toolpath using Mastercam’s Verify module by:
Defining a 3 dimensional block, the size of the work piece.
Running the verify function to machine the part on the screen.

GEOMETRY CREATION
To start a new file from Mastercam:
File
New
Before starting the geometry creation we should customize the toolbars to see the toolbars required
to create the geometry and machine a 3D part. See Getting started.
Operation manager to the left of the screen can be hidden to gain more space in the graphic area for
design. Press Alt + O to remove it.
Before starting the geometry make sure that the Grid is enabled. It will show you where the part
origin is. See Getting started page A 6 for details.
