A Study on the Software Error Compensation of the CNC Machining Center

摘要

Based on MBS method, according to the necessary condition of precision processing, the relationship among the cutter location data, the actual cutter trail, the NC command value has been derived. A new machining accuracy enhancement method is developed based on the reversal kinematics theory. A lot of precision machining experiments have been done on the Beiren group ' s S-1500 three axis vertical dragon machining center. The experiment result shows that the machining accuracy of NC machine can be improved above 60% after used the theory and method of the article.
