| Abstract: | To improve the processing of high-speed machining accuracy and efficiency,the method of Clothoid curve to optimize the toolpath between loops in HSM of pocket is proposed based on the characteristics of the contour-parallel method of pocket,the unsmooth tool-path of knife,and large and uneven milling force.The result indicates that Clothoid curve is more smooth and steady,and milling force is smaller. |
