A MAPPING MODEL BETWEEN THE WORKPIECE GEOMETRIC TOLERANCE AND THE END POSE ERROR OF CNC MACHINE TOOL CONSIDERING STRUCTURE DISTORTION OF CUTTING PROCESS SYSTEM

A mapping model between the workpiece geometric tolerance and the end pose error of CNC machine tool considering structure distortion of cutting process system

Aiming at the problem that the geometric accuracy design index of machine tools is difficult to be determined reasonably Soap Dishes in the geometric precision design process of CNC machine tools, this paper presents a mapping model between geometric tolerance of the workpiece and end pose error (positional and orientational error of the tool relat
