This paper proposes a new real time error compensation implementation method for CNC machine tools. The proposed method reduces the complexity of compensation system significantly, which takes full advantage of numerical control system. The Compensation Control software is developed based on original Human-Machine-Interface software of Siemens 840D numerical control system. Meanwhile, the compensation controller shares the CPU of with the Man-Machine-Communication module. Due to it hardly needs any external devices except some necessary sensors, the proposed compensation strategy greatly reduces the cost of building a compensation system and the stability of compensation system is enhanced accordingly. Experiments have been conducted and the results show that the proposed method can improve the accuracy of machine tools dramatically.

In industrial applications, highly accurate mechanical components are generally required to produce advanced mechanical and mechatronic systems. In machining mechanical components, contour error represents the product shape quality directly, and therefore it must be considered in controller design. Although most existing contouring controllers are based on feedback control and estimated contour error, it is generally difficult to replace the feedback controller in commercial computerized numerical control machines. This article proposes an embedded iterative learning contouring controller by considering the linearly interpolated contour error compensation and Bézier reposition trajectory, which can be applied in computerized numerical control machines currently in use without any modification of their original feedback controllers. While the linearly interpolated contour error compensation enhances tracking performance by compensating the reference input with an actual value, the Bézier reposition trajectory enables smooth velocity transitions between discrete points in the reference trajectory. For performance analysis, the proposed controller was implemented in a commercial three-axis computerized numerical control machine and several experiments were conducted based on typical three-dimensional sharp-corner and half-circular trajectories. Experimental results showed that the proposed controller could reduce the maximum and mean contour errors by 45.11% and 54.48% on average, compared to embedded iterative learning contouring controller with estimated contour error. By comparing to embedded iterative learning contouring controller with linearly interpolated contour error compensation, the maximum and mean contour errors are reduced to 20.54% and 26.92%, respectively.
