Study on Control Algorithm for Continuous Segments Trajectory Interpolation

摘要

In CNC machining,the complexity of the part contour causes a series of problems including the repeated start-stop of the motor,low machining efficiency,and poor machining quality.To relieve those problems,a new interpolation algorithm was put forward to realize the interpolation control of continuous sections trajectory.The relevant error analysis of the algorithm was also studied.The feasibility of the algorithm was proved by machining experiment using a laser machine to carve the interpola- tion trajectory in the CNC system GT100.This algorithm effectively improved the machining efficiency and the contour quality.
