A Speed Smoothing Algorithm in Micro Segment High-speed Machining
A forecasting speed smoothing algorithm based on inflexion velocity has been presented in this paper.According to the geometry characters of the machining trajectory, the inflexions in CNC machining tool path can be confirmed by using the designed algorithm.The line segment between each inflexion can be treated as a continuous path that can be tracked under the continuous feed rate.Moreover the maximal permitted link-up speed can be calculated through dynamic restriction equations and the real-time modification of sinusoidal acceleration can be realized by using the speed iteration algorithm.By simulation analysis, it can be revealed that both the flexibility and efficiency of the CNC machining has been improved and the impact to the machine tool has been greatly reduced.
