One end of a mild steel rod, that is a work piece, was fastened by the chuck of lathe. In the cutting operation during which the revolving workpiece was oscillated slightly by a cam in a horizontal direction and the area of cut was varied periodically, the horizontal displacement of the work and the cutting force were measured simultaneously on a rotating film. The experimental research on the lag of horizontal cutting force behind the horizontal displacement of the work were carried out in certain cutting conditions under which the amplitude of oscillation and the period of oscillation were varied. In these cutting operations the work was apart from the cutting edge in a few period of one cycle or not. By this research, the cause of some characters of chatter, that is, the amplitude of chatter is liable to suddenly increase at a certain depth of cut, and the chatter is liable to cause in the cutting condition of a small feed and a large cutting angle, were well explained. These results also show as previously reported that the chatter is caused by the lag of horizontal cutting force when the area of cut is varied.
