Abstract:

For the CNC machine tool vibration induced by unsmoothed velocity and jerk during beginning /ending stage, an algorithm was proposed combining the linear acceleration/deceleration algorithm with the moving average filtering. The functions of velocity, acceleration, and jerk with respect to discrete time were studied, and the algorithm equivalence to the S-shape acceleration and deceleration was proved. The implementation and experimental results were given in detail. The experimental results show the effectiveness.
