Numerically controlled machine tool and workpiece machining method in this numerically controlled machine tool

摘要

PPROBLEM TO BE SOLVED: To provide a method for working on works with a numerical control machine, which effectively may save energy and keep a high-accuracy machining on the works, by suppressing a vibration generated, when the work is transferred along an axis. PSOLUTION: The method for working on the works, comprising transferring a moving unit along the axis, by utilizing a large amount of time to wait for the other work while another moving unit is working on another works; shorting the waiting time for moving unit or making the waiting time 0 for the moving unit; suppressing shocks and vibrations generated, while a machining speed of the moving unit is accelerated or deactivated, by reducing the machining speed of the moving unit; and saving electric power consumption.
