Path Smoothing Method of CNC Machining Tool Based on Bessel Curve
After applying the conventional method,the path smoothing index and product qualified rate are low.Therefore,a tool path smoothing method based on Bessel curve is proposed.According to high-error judgment condition of the double bow,the piecewise rational polynomial function is used to represent the Bessel curve of the machining area.After selecting the control point,the automatic smoothing of the CNC machining tool path is realized by restricting the Bessel curve.The results show that after the application,the path smoothing index is always above 0.96,and the qualified rate of CNC machining products can reach 98.16%,indicating that this method has a good application prospect in the path smoothing of CNC machining tools.
