Abstract
In this paper, by integrating the look-ahead strategy into S-shape acc/dec algorithm, we propose a novel velocity control algorithm to improve machining quality and processing efficiency in CNC systems. We first propose a path-segment linking model that can deal with both line-connect and arc-connect conditions. Based on this model, we develop a new S-shape acc/dec algorithm with look-ahead velocity control which can deal with the low velocity zone called "tail" in a deceleration zone. Practical algorithms are proposed to find optimal velocity adaptively based on the maximum number of look-ahead segments and geometric properties of the interpolation path. We implement our technique in both simulation environment and real CNC systems and conduct a series of experiments. The experimental results show that our technique can significantly improve machining efficiency and reduce acceleration sudden changes by taking advantage of both S-shape acc/dec algorithm and look-ahead algorithm.
