Abstract
To overcome some shortcomings of the linear Acc/Dec approach and the traditional S-curve Acc/Dec method, a novel velocity planning approach is proposed for CNC machine tools in this paper. The velocity planning model based on moving average technology is structured. The presented approach is used to make velocity planning for the CNC system. Comparing with the linear Acc/Dec algorithm, the presented method greatly improves motional smoothness of the linear Acc/Dec approach and reduces the complexity of the traditional S-curve Acc/Dec algorithm, which is more suitable for high-speed and high-precision CNC machine tools. The proposed approach is tested by simulation and experimentation. Simulation and experimental results have shown that the proposed method can significantly improve the motional smoothness and consumes less resource and shortens processing time for the CNC system.
