Machine tool control system

A machine tool control system comprising:

• a controller for transferring a machining schedule and a machining program corresponding to the machining schedule of a tool center through a local area network and for creating an operation schedule for a monitor control side;
• and
• a numerically controlling device for storing the corresponding machining program sent from the controller in a memory and sending the corresponding machining program to machine tools, wherein
• the controller comprises an automatic transfer system determining section which stores judging rules for judging whether the corresponding machining program should be transferred to the numerically controlling device via a memory transfer system in which all of the corresponding machining program is transferred to the memory of the numerically controlling device or via a direct control (DNC) transfer system in which the corresponding machining program is transferred to the memory of the numerically controlling device block by block, and wherein
• when the corresponding program is to be transferred to the numerically controlling device, the automatic transfer system determining section compares the judging rules with the machining schedule and the corresponding machining program to automatically determine which of the memory transfer system or direct control (DNC) transfer system is more suitable.
