It is well known that the elastic deformation caused by cutting force and the thermal deformation caused by temperature rise are considered to be the main cause of the machining error during the fine boring process of the engine cylinder. In this study, to clarify the proportions of thermal deformation and the elastic deflection in the total machining error, a new experimental method (YAG laser heating experiment) to investigate the influence of thermal behavior on machining error solely was developed. Then, FEM analysis and experiments were carried out (900m/min, F=0.2mm/rev, D=0.3mm, Dry Cutting). The result shows that the deformation caused by the thermal expansion is larger than that caused by the cutting force.
