Influence of cutting modes on power characteristics of rotational turning by multifaceted cutters

Abstract

New data on the effect of technological modes (depth cutting, amf; longitudinal feed, fn; azimuthal feed, faz; cutting speed, Vr) and constructive factors (geometric and kinematic parameters of the tool) on cutting forces have been obtained. On this basis, semiempirical computational formulas Pz = f (amf , fn, faz , Vr) for the assignment of rational modes of processing by the method of rotational turning multifaceted cutter (RTMC) are proposed. The obtained numerical values of the cutting forces for PTMC (up to 900N) are much lower than for сonventional turning (up to 4000N) at similar values of amf and fn.
