Research on Simulation of Acceleration and Deceleration Algorithm with Trigonometric Function Squared Sine Shape Curve

Control of speed and motion of multi-axis system are the key technologies in the opening CNC system. Control of the process of acceleration/deceleration (Acc/Dec) is one of key complicated problems in CNC system development. The excellent Acc/Dec control can improve the machining precision. The traditional Acc/Dec algorithms such as the linear and the exponential are not suitable for high speed motion because there would be flexible impacts existing in feed motion, especially that the jerk of the S-shape curve Acc/Dec is inconsecutive. A new flexible acceleration/deceleration algorithm for high speed motion system based on the Trigonometric Function Squared Sine (TFSS) shape curve Acc/Dec was presented. The simulation experiment results demonstrate that the Acc/Dec algorithm with TFSS shape curve is a new method for the design flexible acceleration/deceleration, the sine curve in jerk, acceleration, velocity and displacement are all consecutive in this algorithm.
