<p>PROBLEM TO BE SOLVED: To provide a production management method for a production type machine tool capable of extending the durable years of a machine. SOLUTION: The working conditions and the number of production of works are stored in an RAM 14. The working time of a machine tool is calculated from the working conditions and the number of production, and whether or not there is any margin in the working time is judged by a central arithmetic processing unit 12. When it is judged that there is any margin, the working time is prolonged by switching to a low speed parameter, and in the other case, the working of the works is carried out with a normal parameter.</p> |
