"Calculations for Programming the Mill" provides an in-depth explanation of the various calculations necessary to program toolpaths on a CNC mill or machining center for a variety of common operations. Common CNC milling operations covered in this class are face milling, pocket milling, milling full and partial arcs, and holemaking. Important concepts for programming these toolpaths include step-over, approach distance, trigonometry, and boxing routines, as well as some of G codes. "Calculations for Programming the Mill" details the calculations necessary to program a CNC mill. After taking this class, users will be able to understand and perform most basic CNC mill operations.
