Abstract

This thesis proposes an on-machine measurement methodology for identification and compensation of location errors of rotary axis on machine tools by using a touch-trigger probe and a precise sphere The advantages of this measuring system are not only convenient for installation and operation but also can be applied to different configurations of machine tools This thesis takes the horizontal boring and milling machine BMC-110FT2 produced by Far East Machinery as the research vehicle The aim of this thesis is to measure the location errors between the facing head and the spindle of this machine These location errors lead to the problem that the inner and outer holes are not concentric in the boring workpiece By establishing the geometric error model and analyzing the difference between the ideal and real center positions of the precise sphere when the facing head of this machine is at different angles the four location errors of the rotary axis of the facing head are calculated At the end of the experiment the measured location errors are compensated to the controller The results show that the deviation of the inner and outer hole concentricity of the boring workpiece is significantly reduced to 0 024 mm from 0 179 mm after compensation It is expected that this method can be applied to more situations as an on-machine measurement solution for quickly analyzing the geometric errors of rotary axis on machine tools
