Abstract

CNC (Computer Numerical Control) machine tools are required to have high accuracy and production efficiency. CNC machine tools generally generate trajectories such as position and speed within the NC system for commands (usually G code), and then drive each axis. However, in actual contouring motion, the machine often does not move perfectly as commanded, due to tracking errors such as response delays in the control system. NC device manufacturers seem to apply deceleration process to reduce these errors, but their methods have not been disclosed. In this research, we focused on contouring motion with steep acceleration/deceleration, discussed the contouring accuracy when driving the feed drive mechanism with the acceleration/deceleration command generated by the motion controller and our proposed method. Typical NC control controller for machine tools generate trapezoidal or S shaped acceleration/deceleration commands. We propose a command design method based on the Preshaping method which is also known as a vibration suppression method and report the contouring accuracy when applying this method.
