Abstract

PURPOSE:To improve processing accuracy and the quality of a plane to be processed and to realize the easiness and the high efficiency of programming, by assuming the shape of a micro block nearest to a true shape by applying circular arc approximation, and deciding feed speed automatically based on the assumed shape. CONSTITUTION:The radius of a second virtual circular arc is found by averaging the radius of a first virtual circular arc passing the command point of an arbitrary block and that of one preceding or succeeding block, the radius of the first virtual circular arc corresponding to several blocks before the arbitrary block, and the radius of the first virtual circular arc corresponding the several blocks behind the arbitrary block. And a driving part is controlled by finding the radius of a third virtual circular arc corrected so as to minimize a difference between the second virtual circular arc and the command shape of the arbitrary block, and also, correcting processing tolerance so as to conform with the third virtual circular arc, and finding the feed speed based on the radius of the third virtual circular arc and corrected processing tolerance. In such a way, it is possible to improve the processing accuracy and the quality of the plane to be processed.
