NUMERICAL CONTROL WORKING MACHINE AND ACCELERATION/ DECELERATION CONTROL METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a numerical control(NC) working machine and an acceleration/deceleration control method therefor with which cutting working time is shortened regardless of the cutting feed speed of the NC working machine and feeding operation can be smoothly performed without mechanical shock. SOLUTION: An acceleration/deceleration curve parameter corresponding to the cutting feed speed of the NC working machine is found by an acceleration/deceleration curve parameter determining part 17 and, on the basis of the acceleration/deceleration curve parameter found by the acceleration/deceleration curve parameter determining part 17, the acceleration/deceleration of cut feeding is controlled by an interpolation acceleration/deceleration control part 9.
