This paper focuses on contouring errors appearing during the execution process each stages of the process (CNC interpolation, feed drives). The so-called CEC Contouring Error Compensation) method which stands for a temporal mirror approach is developed in this paper. The modification of the trajectory setpoint so that the executed actual trajectory matches the CAM trajectory proves to be efficient as contouring errors are significantly decreased.
