<p>PROBLEM TO BE SOLVED: To minimize the operation stop time of a machine tool by preparing another file so as to be able to compute tools to be used without breaking the synchronization of a file that is synchronously fetching the working state of spare tools. SOLUTION: Tools used for machining according to unmachined NC data in machining during schedule operation are computed from the tool computed result and a virtual tool pot control file obtained in steps S1, S2 (step S3). In the case of confirming the insufficiency of tools by a judgment made in a step S4, if there is a shortage on the tools in want, around what time machining with the use of the tools judged to be in want is started with the present as a starting point, is displayed or printed in addition to information of the service time of the tools (step S5). The tools in want and required for a worker are informed in a list, screen display or the like (step S6).</p> |
