Studies of the Vibration-Assisted Cutting of Rock by Toothed Equipment

摘要

The effects of frequency, amplitude of displacement of sinusoidal vibro-cutting, velocity and depth of cutting on the maximum excavation force were investigated for a tuffaceous rock. It was verified that the ratio of horizontal component of the maximum excavation force at vibro-cutting and that at non-vibration decreased hyperbolically with the increment of the velocity ratio and depth of cutting, and the ratio of specific energy at vibro-cutting and that at non-vibration also decreased hyperbolically with the increment of velocity ratio but increased parabolically with the increment of depth of cutting.
