Motion performance analysis and control mode design for the cross slide

The motion control system which is constructed by using the programmable controller and the motion controller has been widely applied to various mechanical systems. This paper takes a cross slide as an example, the motion control system is composed of the GE FANUC PAC and DSM324i, and the movement performance simulation model is established. The motion performance by linear acceleration and deceleration algorithm in the case of two axis synchronous movement is analyzed. The relation between the displacement command and the parameters of the acceleration and the velocity is derivated, and the trajectory curve of movement performance under a variety of instruction is gained. The control instruction meet the linear motion is designed by the model.
