The invention is applicable to the technical field of
numerical control machine tools, and provides a massager
metal plate milling device, which comprises a
milling cutter rotating speed adjusting module, a main shaft rotating speed adjusting module and a
milling cutter rotating speed adjusting module, wherein the
milling cutter rotating speed adjusting module is used for constructing a main shaft rotating speed adjusting model according to a reference main shaft rotating speed, a
machining precision confidence coefficient, a
flutter main
frequency band energy ratio and a
flutter main frequency value when the
machining precision confidence coefficient is lower than a preset threshold value; outputting the milling cutter rotating speed adjusting quantity and controlling the milling cutter rotating speed to adjust; and the
cutting depth adjusting module is used for constructing a
cutting depth adjusting model according to the workpiece thickness, the dynamic state index, the workpiece state index and the reference
cutting depth and outputting the cutting depth adjusting amount when the
machining precision confidence coefficient is still lower than a preset threshold value after the milling cutter rotating speed is actively adjusted. By means of the massager
metal plate milling device, the problems that in the prior art, the machining state cannot be sensed in real time, the self-adaptive adjusting capacity is lacked, and graded intervention and automatic alarm functions are lacked are effectively solved.
