METHOD FOR CORRECTING MOVEMENT PATH OF NUMERICAL CONTROLLER, COMPUTER-READABLE RECORDING MEDIUM WITH RECORDED PROGRAM MAKING COMPUTER IMPLEMENT THE METHOD, NUMERICAL CONTROLLER, AND PROGRAM CONVERTER

摘要

PROBLEM TO BE SOLVED: To avoid adverse influence of corner speed reduction, caused by a noise block in a program, on a machined surface when a program composed of fine segments is run under NC. ;SOLUTION: After a program input part 2 generates segment data of a path, a correction part 3 checks three successive segments; if there is a segment which is shorter than a set value and connected zigzag to its precedent and following segments, the movement quantity of this segment is distributed to the precedent and following segments and this segment is deleted to correct the machining path, thereby performing speed control including corner speed reduction over the corrected path.;COPYRIGHT: (C)2001,JPO
