Abstract: In traditional computer numerical control (CNC) machine tools, the motion of each axis is controlled independently. However, the uncoupled system can't achieve good contour performance when linked axes actual dynamic performances don't match well. Consequently, the parameter-average contour error coupled-control approach based on grating sensors for NURBS curve cutter path machining is developed in the paper, which includes how to compute contour error and contour error correction quantity with high-accuracy for linked axes on each sampling period mainly. Above all, the parameter-average contour error computing model is put forward, which is independent of tracking error. Secondly, a simple and effective contour error correction quantity algorithm is built up. Lastly, the introduced contour error coupled-control approach for NURBS curve cutter path machining is verified on the three-axis linked CNC test table. The experimental results show that the introduced approach can reduce contour error effectively for NURBS curve cutter path.

 

Keywords: Dynamic performances, NURBS curve, Grating sensors, Contour error, Coupled-control.
