Abstract

The present invention discloses a numerical control machine tool follow-up processing device and a follow-up method thereof. A laser emission and receiving device is arranged to perform feedback of the interference in the processing process through the changing of laser light spots, and a negative pressure sucker and a rubber gasket are arranged to improve the work stability of the laser system. The deficiencies can be solved in the prior art, and the accuracy of the operation of the whole numerical control machine tool can be improved.

Description

technical field [0001] The invention relates to the field of automatic control of machine tools, in particular to a follow-up processing device and a follow-up method for a numerically controlled machine tool. Background technique [0002] In the automatic processing of CNC machine tools, it is necessary to change the position of the tool and the workpiece in real time, so as to realize the precise processing of the workpiece. In the prior art, in order to improve the machining accuracy, the precise movement of the servo motor is usually achieved by improving the manufacturing process of the servo motor. However, during the cooperative operation of multiple servo motors, the motion error of each servo motor will greatly increase the error degree of the entire CNC machine tool. Chinese invention patent CN 102130640 B discloses a multi-axis synchronous servo drive system and a synchronous control method thereof, in which synchronous signals between servo controllers are used ...
