Chatter vibration avoiding device, chatter vibration avoiding program, and control method of chatter vibration avoiding device

摘要

To avoid chatter vibration in various cutting processes.SOLUTION: The chatter vibration avoidance device (1) calculates the attenuation degree indicating how much the chatter vibrations are attenuated per predetermined number of rotations of the rotary tool for each position of the rotary tool inside the workpiece An attenuation degree calculation section (233), and a display control section (234) for displaying the attenuation degree calculated by the attenuation degree calculation section.BACKGROUND OF THE INVENTION
