Title: Identification the Motion Error of Machine Tool Based on the Correlation Analysis
Abstract: Machine tool has been widely used in the production of the military and civilian.The machining precision of the workpiece is the direct reflection for the machining performance of machine tool.With the improvement for requirement of the machining precision,improving the accuracy of machining is becoming important.Guideway and spindle are the key motion components that decided the shape,the relative position and the surface roughness of the workpiece.In order to adapt to the requirements of the workpiece machining,this paper analyzes the errors of guideway and spindle that affect the accuracy of the processing,establishes the motion relations for every errors of guideway in machining process,identifies the regular for the straightness,bending of the guideway and rotating error of spindle that influences the workpiece surface.Finally,according to the correlation analysis of the measured and the simulation results,the motion error of machine tool is identified,which lays the foundation for improving the accuracy of machine tool in next step.
