FEEDBACK CONTROL NUMERICAL MACHINE TOOL AND METHOD THEREOF

摘要

A feedback control numerical machine tool and a method thereof are provided. The machine tool includes at least two spindles, an acoustic frequency detecting module, at least two spindle position detecting modules, and a control module. The spindles machine a workpiece. The acoustic frequency detecting module detects an acoustic frequency of the spindles when machining the workpiece. The spindle position detecting modules detects position information of the spindles when machining the workpiece. The control module acquires the acoustic frequency and the position information of the spindles, monitors whether any of the spindles chatters according to the acoustic frequency of the spindles, and performs chattering avoidance to the spindle that chatters according to the position information of the spindles. As such, the present disclosure performs chattering monitoring to a plurality of spindles and avoids the chattering immediately.

主权项

1. A feedback control numerical machine tool, comprising:
at least two spindles that machine a workpiece; an acoustic frequency detecting module that detects an acoustic frequency of the spindles when machining the workpiece; at least two spindle position detecting modules that correspond to the spindles, respectively, and detect position information of the spindles when machining the workpiece; and a control module connected to the acoustic frequency detecting module and the spindle position detecting modules, that acquires the acoustic frequency and the position information of the spindles, monitors whether at least one of the spindles chatters according to the acoustic frequency of the spindles, and performs chattering avoidance to the spindle that chatters according to the position information of the spindles.
