A S-shape Curve Speed Control Algorithm of Continuous Micro-lines Interpolation Based on Adjustable Feed-Speed
To satisfy the need of high speed machining,according to machines features and turning angle between micro-lines,constraining conditions of micro-lines turning feed speed are established in this paper.The algorithm is calculating the resolution of the end velocity of last line and the startup velocity of next line,and then deduce the acceleration on each axis.The resolution acceleration of each axis reflects the loading capacity of them and should not over a given value.Then a S-shape curve speed control algorithm of continuous micro-line interpolation based on adjustable real-time feed-speed is designed.When maximum feed velocity in a line changes from a low value to a high one suddenly,the velocity also tends to target smoothly by S-shape curve,and the velocity decreases to the end speed value in advance,and the total interpolation time decreases,machining efficiency rises evidently.At last,experiment which performed on the CNC system verifies the control algorithm.The result indicates that the algorithm can enhance the machining efficiency and improve surface quality based on assuring the machining precision.
