Simulation Study of Motion Control for X-Y Table with a Novel Direct Contour Controller

Abstract:

Contouring accuracy is important in multi-axis computerized numerical control (CNC) machining. This paper proposed a direct contouring control (DCC) strategy for CNC contouring applications. The DCC implements velocity control in the tangential direction and position control in the normal direction, which is different from conventional axis-based position control schemes. The real-time contouring state monitoring method is introduced to obtain the necessary information for DCC. The motion profile is defined as a velocity-displacement function along the tool path. A new velocity interpolator is proposed to generate the tangential velocity command for DCC. A simulation experiment based on X-Y table model with circular trajectory is conducted to test the performance of the proposed method. The results show that the DCC can achieve high contour accuracy with a simple structure.
