Design and Implementation of Rotation Around Tool Center Point Algorithm for 5-Axis CNC
To realize high effective 5-axis maching,the RTCP technology is deeply studied in this article.By the revolving angle subdivision and the non-linear error compensation at the interpolation point,the non-linear error has been decreased and the realtime capability for compensation has been ensured.By the foreseen control for the velocity and acceleration of cutter control point,the machine tool oscillation has been minished,so as to improve the quality of the workpiece exterior.The writer has put forward the union kinematics model based on the parameters configuration to improve the transplant performance of the workpiece programme.Finally,the algorithm has been added to the GJ-310 NC system and the efficiency of the algorithm has been validated.
