摘要: A model-referenced adaptive control strategy combined with cross-coupled of axial motion that is intended to improve contouring performance multi-axis computer numerically controlled machine tools discussed. feedback loop established between the desired input feedrate and output contour error. By specifying a error bound, feed rate adaptively adjusted online so resultant accuracy can be maintained within specified bound. The development an experimental positioning system for implementing proposed described. Experimental work on this shows effectiveness method. >
