This paper describes experimental studies on three dimensional cutting by sidewise movement of cutting edge (called drift cutting). Drift cutting is very similar to oblique cutting in respect of geometrical relations between work material and cutting tool. Comparison between these two cutting methods shows smaller cutting resistance and better surface finish in drift cutting. The reason is that small amount of lubricant such as absorbed molecules or cutting fluid on the tool face may be brought into tool-chip interface by sidewise movement of cutting edge. Shapes of chips in drift cutting sometimes show triangular crosssection because of difference of friction at each point on the tool face. Frictional force caused by the sidewise movement of cutting edge promotes the deformation of chips.
