This paper proposes a novel fourth-order S-shape acc/dec control algorithm by use of the parameter restriction that applied in CNC simulation system possessed of wireless communication. Firstly, the acc/dec control strategy of equivalent trapezoid is studied. Then, the real kinematics parameters of fourth-order S-shape curve are analyzed under the condition of speed–acceleration constraint, displacement–acceleration and displacement–speed based on the proposed control strategy. Based on the system dynamics constraints and considering the seven control stages of the algorithm, the forth-order S-shape curve acc/dec control algorithm with time optimization is proposed through pre-processing. The effectiveness and reliability of the algorithm are verified through a calculation instance. Finally, the proposed algorithm is successfully realized on the newly developed CNC simulation system with instruction interpretation possessed of wireless communication. The research results will provide the theoretical basis for the simulation system and further promote the development of the virtual manufacturing system.
