Abstract

By the use of the developed mathematical model and the method of parametric optimization of wear and
resource of a metal-cutting tool, it was found out that at operating a metal-cutting carbide inserts of B35 alloy
strengthened by the aerodynamic sound method, by intermittent milling of GC20 cast iron at optimal cutting
conditions equal to v = 146.5 m / min, sz = 0.09 mm / tooth, t = 3.1 mm, the tool’s resource is increased by 209 %. The
method of aerodynamic sound hardening is recommended not only to increase the resource of metal-cutting carbide
tools used in intermittent cutting processes, but also to increase the productivity of processing.
