This paper treats experimental results on the mechanism of metal cutting with oscillating tools. In order to measure the cutting forces precisely, it is desirable that a tool be vibrated with a low frequency because there are many troubles in the experimental procedure of cutting if the tool is oscillated with a high frequency. Aluminum and brass are machined two-dimensionally with tools vibrated with 33 c/sec frequency and 0.2 mm amplitude. The depth of cut is varied from 0.03 to 0.15 mm and the rake angle from 0 to 40 deg, at the surface speed of works of 0.37 m/min. The cutting forces increase gradually with the increase of cutting distance in one cycle. This is more evident for the thrust force than for the principal force. Further investigations are now performed on the coefficient of friction on the tool-chip interface, the stress in the shear plane, and the effect of elliptical movement of a tool on the thrust force.
