Application of Optimizing CNC Machining Speed Error Based on LMS Filtering Algorithm
For the problem of low machining accuracy caused by speed errors during CNC machining process,the machining accu-racy,cutting acceleration and deceleration errors and the variation law of cutting acceleration of the processed parts were studied.An op-timization of CNC machining speed error based on LMS filtering algorithm was proposed.Non-uniform rational B-Splines(NURBS)were simulated and processed,and the machining speed of CNC machine tools was adaptively controlled.The least mean square was in-troduced for error analysis,thereby improving the accuracy of interpolation speed,reducing the machining error of CNC machine tools,and improving the efficiency of CNC machining.The proposed error control method was validated and analyzed through experimental tes-ting.The results show that optimized CNC machining error control based on LMS filtering algorithm not only improves the machining speed of CNC machine tools,but also effectively solves the problem of machining errors in the machining motion process of CNC ma-chine tools,machining accuracy is effectively improved.It is proved that the proposed machining error control method is feasible to a cer-tain extent through experimental tests.
