The mechanism to cause curved profile of cut surface in band sawing is studied from both analytical and experimental points of view. The simulation model is built taking into account the guide error of the bandsaw blade, the inequality of the sharpness and setting angle of the bandsaw teeth, the bending and torsion stiffness of the bandsaw blade and the thrust force per tooth per unit thickness, to show the validity of the model in explaining the curvature of cut surface. The discrepancy observed between the analytical and experimental results with regard to the effect of .the guide error of the bandsaw blade is considered due to the neglect of the unstable state at the initial stage of cutting in the model. Finally the attachment which enables one to adjust the guide angle of the bandsaw blade is proved effective in reducing the undesirable curvature of cut surface.
