Moving-average-based CNC Simulation System with NC Instruction Interpretations
The paper presents a novel acceleration/deceleration (acc/dec) control algorithm based on moving-average.The proposed algorithm makes use of the moving-average method to dispose the velocities of all the discrete points obtained by linear ace/dec control algorithm.The acceleration curve is continuous and the speed curve is smooth obtained by this method.Furthermore,the proposed algorithm has easier calculation to achieve.Therefore,CNC simulation system with NC instruction interpretation is established based on this proposed algorithm.The system not only simulates the executive process of NC program files,but also realizes the simulation of speed and acceleration curve,process time and distance with the unit of controlling period.At the same time,the simulation system considers the ace/dec control of feed speed therefore the simulation time equals the real process time.Those wilt be the value of the instruction to the process of the real machining.
