Abstract
As part of the search for a new cutting mechanism, a few largely empirical investigations into ultra-high-speed machining (velocity greater than 500 ft/s) have been performed in the past. A comprehensive review of this and other work related to machining at very high cutting speeds is presented and the physical factors predominating in UHSM are discussed. As a consequence of this a new theory of cutting forces at ultra-high speeds is presented, based on inertia and temperature effects, adiabatic shear, and strain-rate dependent yield stress. This theory shows that workpiece properties greatly influence force behaviour, the latter determining the feasibility of machining at ultra-high speeds.This publication has 9 references indexed in Scilit:
