A novel algorithm is addressed for acceleration and deceleration planning of five-axis CNC (Computer Numerical Control) System, aiming at vibration of CNC caused by the velocity and acceleration of rotation axis beyond the limit range of the machine tool. The algorithm uses trigonometric functions to plan the velocity, acceleration and jerk, and carries on the kinematic constraints of the translational axis and the rotation axis. Experiment shows that this is a simple and effective algorithm to achieve continuous velocity, acceleration and jerk within the limited range of five-axis CNC System, thereby reducing machine vibration and achieving high speed, high efficiency and high precision machining.
