NUMERICAL CONTROL CORRECTION MACHINING METHOD OF MACHINED FACE, AND DEVICE FOR FORMING CORRECTION MACHINING NUMERICAL CONTROL DATA

摘要

PROBLEM TO BE SOLVED: To provide an NC correction machining method of machined face and a device for forming correction machining NC data, through which a correction face element the uncut quantity of which exceeds an allowable value to a target shape of a plurality of face elements constituting a machined face of a work can be correction-machined without generating a difference in level from a face element adjacent to the correction face element with the same machining face property. SOLUTION: A plurality of face elements constituting the machined surface machined by a tool is measured by a measuring device, and the correction face element the uncut quantity of which exceeds the allowable value to the target shape and the adjacent face element part adjacent to this correction face element are set as a corerction machining area. The correction face element is correction-machined with a correction machining margin according to the uncut quantity, and the adjacent face element is correction-machined with a correction machining margin gradually increased so as to smoothly connect with the edge part of the correction-machined correction face element.
