Abstract: Disclosed is a connection method of placing and receiving an order for mold machining through the web-based system for real-time utilization of idle facilities for mold, comprising: entering information relating to holding facilities held by the subcontractors for mold machining in database, wherein the subcontractors are members entering the information and receiving an order for mold machining; and searching the database for the information relating to holding facilities, wherein the mold manufacturers are members searching the information and placing an order for mold machining; wherein the subcontractors enter idle time period of idle facilities of the holding facilities in database and the mold manufacturers regard the idle facilities for the idle time period as the facilities held by the mold manufacturers, whereby ERP scheduling is possible.

Abstract: Disclosed is a controller for an automatic machining device which conducts machaining of a workpiece based on NC data. The controller comprises a data input section to which NC data are inputted; a database storage section for storing optimal machining data optimized for machining conditions; an operating section for comparing the NC data and the optimal machining data and calculating optimized NC data; and a control section for controlling the automatic machining device in conformity with the optimized NC data calculated by the operating section.
