Milling Operations• Facing: removes material across the top surface• Contouring: removes material to a specified depth
along a CAD geometry• Drilling: uses points identified on a CAD layer to
drill holes to a specified depth• Pocketing: removes all material within the outline
of a CAD geometry• Surface of Revolution: removes all material within
a surface generated by revolving geometry about the X or Y axis
