Abstract
Several effects of frequency, amplitude, cutting velocity, cutting depth and rake angle of blade on vibro-cutting properties of a blade against cement mortar were investigated experimentally. As a result, it was observed that the ratio of the principal cutting resistance during sinusoidal vibration of frequency 20Hz to that of non-vibration state decreased to be 70 to 80%. The ratio of the principal cutting resistance or the specific energy during vibration to that during non-vibration was clarified theoretically and experimentally to decease hyperbolically with the increment of the speed ratio defined as the product of the angular velocity and the amplitude divided with the cutting speed.
