Chamfer milling consists of milling chamfer-like surfaces. You can chamfer-mill a single chamfered edge, a single chain of chamfered edges (open on both ends), or a single closed loop of chamfered edges. For example, on top of a Pocket feature. You must use a tool of the type Chamfering, Drilling, or Countersink, with the Point Angle parameter of the tool corresponding to the chamfer angle. For example, if you have a 45 degree chamfer, use the tool with the Point Angle of 90 degree.

The parameters used for machining are CUTTING_DIAMETER, NUMBER_FIRST_FINCUTS, NUMBER_LAST_FINCUTS, FIRST_FINCUT_OFFSET, LAST_FINCUT_OFFSET,CORNER_FINISH_TYPE, INTER_RET_HEIGHT, PERCENT_LENGTH, SIDE_CLEARANCE, and TOOL_OVERLAP. Here the CUTTING_DIAMETER defines the point on the tapered tool which follows the basic contact point on the chamfer.
