Autonomous Trajectory Tracking and Contouring Control of Three Dimensional CNC

In this study we analyzed a three- axes computer numeric control (CNC) machine. Here improve the trajectory tracking and contouring performance of both linear and circular trajectories of a CNC. This paper introduced an autonomous method for better trajectory tracking and contouring by different position sensors are placed on three-axes of CNC machines. So reduce trajectory error and contouring error of CNC machines. This method is best solution for improve the trajectory tracking ability and precision of a CNC machine for both linear and circular trajectories.
