Abstract

The purpose of the present invention is to provide a vibration suppression device capable of suppressing chatter vibration of a cutting tool during cutting and achieving high cutting efficiency. The vibration suppression device (1) is for suppressing vibration of a cutting tool (91) being fed while rotating and has: a vibration detection means (11) for detecting vibration of the cutting tool (91);a vibration analysis means (13) for analyzing the vibration of the cutting tool (91) on the basis of the vibration detected by the vibration detection means (11); and a tool control means (12) for controlling the feed speed of the cutting tool (91) on the basis of the analysis result of the vibration analysis means (13). The vibration suppression device (1) is configured such that the tool control means (12) causes the feed speed of the cutting tool (91) to be increased when the vibration analysis means (13) has detected that the magnitude of chatter vibration of the cutting tool (91) is equal to or less than a threshold value.

Description

technical field [0001] The present invention relates to a vibration suppressing device, and more specifically, to a vibration suppressing device that is used with a machining device having a cutting tool and suppresses chatter of the cutting tool. Background technique [0002] When a workpiece such as a metal material is cut by a machining device having a cutting tool such as an end mill, vibration of the cutting tool becomes a problem. The vibration generated between the cutting tool and the workpiece is called chatter. Chatter may cause deterioration of finished surface quality and damage of cutting tools. In addition, since the machining load cannot be increased under conditions where chatter vibrations are generated, machining efficiency decreases due to chatter vibrations. [0003] As described in Non-Patent Document 1 and the like, various chatter vibrations having different generating mechanisms are known. Main chatter vibrations include forced chatter vibrations a...
