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.

A method of controlling the indexing of magazine pockets in a machining center. The tools used in a current machining program are compared with the tools to be employed in the next machining program. When there are tools used in both programs, the pocket numbers of the tools in the present machining program are indexed to the identical tools to be used in the next machining program. The data concerning such common tools are displayed together with the indexed pocket numbers.
