In this study a geometrical adaptive control (GAC) scheme is proposed to compensate a form generating movement error of a CNC machine tool caused by various deformations of machine systems. In the proposed GAC system, the machining error is reduced by a tool path modification incorporated with the machined workpiece profile data which is obtained by a between-process measurement. An analysis for the stability condition of the GAC system shows that the machining system becomes unstable due to the tracking error of its servosystems. There fore the GAC algorithm is installed in the controller of a CNC machine tool with an adaptive feedforward controller for compensating the tracking error of the servosystems. The machining results show that the GAC system operates stably and reduces the machining error considerabiy.
