ABSTRACT:
A numerical control system for controlling a machine tool includes a central processing unit, a first memory for storing a first control program, a second memory for storing a second control program, and a third memory for temporarily storing data. Each of the first memory, second memory and third memory is connected to the central processing unit. An interface circuit couples a machine tool to the central processing unit. The interface circuit sends signals to and receives signals from the machine tool. The first control program sends signals to and receives signals from the third memory based on a standard interface with the machine tool. The second control program sends signals to and receives signals from the machine tool via the interface circuit based on an interface corresponding to the machine tool. The second control program also sets a signal from the machine tool in the third memory after converting it to a signal based on a standard interface.
