Automatic programming apparatus for control apparatus of numerical control (NC) machine tool, has program generation unit that assigns several grades for processing workpiece according determined procession mode

摘要

A program generation unit (25) generates tool path data and feed rate of tool, and generates NC program. A processing mode determination unit (26) determines processing mode such as rough, inside finishing, finishing modes for processing workpiece according to the finish shape, finishing stock and tool used. Several grades are assigned for processing workpiece according determined procession mode. The processing mode is determined according to manufacturing process when processing locus of movement path of tool does not intersect with finish shape of workpiece.
