SYSTEM FOR SUPPORTING NC MACHINING

摘要

The present invention is characterized in that: a plurality of NC machine tools (28) each including NC program generating means and NC program improving and updating means are connected to a central manager (1) via a network; actual machining performance information is supplied to the central manager (1) from the respective NC machine tools (28); the central manager (1) generates databases (3 to 12) from the collected actual machining performance information and stores the database (3 to 12) therein; and the NC machine tools (28) are each permitted to retrieve information necessary for machining from the database (3 to 12).
