Abstract
A machine tool rapid compensation system includes: a trigger acquisition module, a laser interferometry measurement module, a data analysis and compensation module, and a communication module. The trigger acquisition module receives a trigger acquisition instruction, converts an encoder position value into a pulse value, transmits the pulse value to the laser interferometry measurement module, retrieves parameter information and compensation point information of a machine tool from a numerical control system, and generates a machine tool operation code and a measurement preparation signal. The laser interferometry measurement module receives the measurement preparation signal and the pulse value to obtain error data, environmental data, and expansion compensation values. The data analysis and compensation module collects the error data, the environmental data, and the expansion compensation values to obtain precision parameters and compensation parameters, and transmits the precision parameters and the compensation parameters to the numerical control system through the communication module.
