Abstract

A tolerable feed rate is calculated to cause mechanical shock not exceeding a tolerable level in an arcuate machining based on the radius of the path of tool movement at arcuate machining portions and the predetermined tolerable acceleration. A deceleration start timing is set by reference to the end of an arcuate machining and the predetermined deceleration so that the feed rate is lower enough to maintain the tolerable mechanical shock at the end of an arcuate machining. An optimum feed rate is set for arcuate and completely circular machining based on the classification judgment of the arc or complete circle.
