This paper presents the methodology of measuring the instantaneous cutting forces during vibratory cutting. It is based on elastically supported dynamometer vibrating with the tool during chatter. Acceleration of the dynamometer measured simultaneously allows for evaluation and elimination of inertia forces acting on the oscillating dynamometer. Displacements of the dynamometer and the tool in the feed direction during orthogonal cutting are measured by the contactless inductive sensor. The measurements allow for determination of averaged or instantaneous dynamic cutting force coefficients and their dependence on cutting conditions.
