碩士 === 國立臺灣科技大學 === 機械工程研究所 === 83 === In this thesis, a geometrical adaptive control strategy has been developed to improve the machined surface profile error in milling. First, a feedforward and cross-coupled biaxial contour control system for a CNC milling machine is constructed. Then, the relationship between the cutting force and tool deflection is established. Based on the relationship between the cutting force and tool deflection, an on-line contour compensation method is proposed. Experimental results have shown that not only the waviness error but also the location error of workpiece can be greatly improved.
