VERFAHREN ZUR BEURTEILUNG UND STEUERUNG GLEICHZEITIGER BEARBEITUNGSVORGAENGE IN EINER QUADRIAXIAL-NUMERISCH GESTEUERTEN DREHBANK

摘要

A method of judging and controlling simultaneous machining in a quadriaxial numerical control lathe having two tool rests. A machining pattern pair memory stores a pair table showing possibility of simultaneous execution of different machining patterns. A judgement is made as to whether a simultaneous execution of two machining processes in accordance with input machining informations is possible, through a retrieval of the table in the machining pattern pair memory, and machining programs for two tool rests are formed through an automatic judging concerning the possibility of simultaneous machining to relieve the programmer from the work for making such a decision.
