Design of CNC Machine Tool Drive Shaft Position Signal Acquisition and Linear Error Compensation
In order to improve the linear error compensation capability of CNC machine tool drive shaft position,an error compensation method is used to collect the position loop signal of the machine tool servo system,and a CNC machine tool drive shaft position signal acquisition and linear error compensation method is designed.A temperature measurement method is introduced to collect the temperature of the measured point,and the test data are corrected to calculate the temperature deviation compensation value to achieve the function of linear error compensation for this system.The results of the study show that the reconstruction variance has been increased,a smaller maximum error has been formed,and the curvature integral recursion process has obtained a smaller error,achieving a better reconstruction result.The compensation of various types of errors is implemented in a specific way,and the form of linear error is adopted to realise the function of real-time compensation of machine coordinates.This study has good practical value and can be applied to other types of machine tools in the field of precision control.
