STEP 1: SELECT THE MACHINE AND SET UP THE STOCK In Mastercam, you select a Machine Definition before creating any toolpath. toolpath. The Machine Definition  is a model of your machine’s capabilities and features. It acts like a template for setting up your machine. The machine definition ties together three main components: the schematic model of your machine’s components, the control definition that models your control capabilities, and the post processor that will generate the required machine code (G-code). For a Mill Essentials exercise (2D toolpaths), we need just a basic machine definition.

operations. Note that we do not have to chain any geometry to create the toolpath because of the extra material we specified on the right face in the stock setup. You can also select points to dictate where Mastercam will create the facing operation.
