- Abstract
For the problem of low machining accuracy caused by speed errors during CNC machining process, the machining accuracy, cutting acceleration and deceleration errors and the variation law of cutting acceleration of the processed parts were studied. An optimization 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 introduced 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 testing. 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 machine tools, machining accuracy is effectively improved. It is proved that the proposed machining error control method is feasible to a certain extent through experimental tests.
