Automatic programming apparatus

摘要

An automatic programming apparatus 1 comprises: a tool path data generating section 12 which generates movement path data for a semifinishing tool by analyzing an NC program; a work shape data generating section 16 which computes areas over which blank is to be machined on the basis of the movement path data, and which generates shape data of a semifinished workpiece by deleting the machined areas from the shape of the blank and also generates attribute data indicating that the faces newly generated by the deletion processing are machined faces; a CL data generating section 20 which generates CL data by setting the edges of the machined faces as machining portions on the basis of the shape data of the semifinished workpiece and attribute data; and an NC program generating section 23 which converts the CL data into the NC program for performing the chamfering.
