<p>PROBLEM TO BE SOLVED: To prevent previously a machining defect caused by an estimated error of a feed forward control. SOLUTION: A determination means varies the contents of the operation that an operation means executes by outputting an operation condition signal to the operation means in response to a machining condition set by a command output means. The machining conditions, whose estimated error becomes larger in F/F control, is made to be previously registered in an NC unit, and when these machining conditions are selected, a output signal of the F/F control means is varied by the command of the determination means.</p> |
