Research on Transfer Control Strategy in CNC High-speed and High-accuracy Machining
Feed rate has always been one of the most important indicators for CNC performance, while transfer velocity between two adjacent segments pays a key role in improving feed rate. Since the contour of a special part commonly consists of line and arc segments (non-micro segments), as well as continuous micro line segments (micro segments) .so there should be different methods to deal with their transfer velocity, respectively. In this paper, a new two-pass algorithm is proposed to find the optimal transfer velocity for micro segments. The theory of machining links and several constraints are developed to drive the algorithm. Then, a vector transfer algorithm is generated to realize transfer for non-micro segments, the generated algorithm is based on s curve and added to a new optimization algorithm to constrain the velocity, acceleration and jerk at the turning corner Finally, several examples are presented to illustrate the application of above two algorithms.
