ABSTRACT:
In the present invention, the breakage of a cutting tool is sensed during a cutting operation of stock on a lathe. A boundary is defined around the stock. The cutting tool is withdrawn stepwise along the same path taken up to the point of breakage. After each step, inquiry is made as to whether the tool has crossed the boundary. When it does, the tool is brought directly to a tool changing station without further stepwise withdrawal.
