METHOD OF PREPARING NC PART PROGRAMS FOR LASER MACHINING

摘要

Method of prepg. NC PERT programs for laser machining comprises input of graphics definition statements (11a) defining a shape and motion definition statemetns (11c) defining a laser beam path, conversion of these statements to an NC PERT program and prepn. of machining conditions change definition statements (11b) contg. data defining conditions change regions at corners and the machining conditions in these corner regions. The graphics and motion definition statements are prepd. disregarding the corner regions and machining conditions and when they are used to produce the NC PERT program each corner region is divided into two or more machining conditions change sections (11,12) and the machining conditions in each section are set by respective macros (12).
