Abstract

Keywords

Specific properties of plasma-sprayed materials cause

major difficulties at edge cutting machining, which lead to

extremely low-efficient tool life, as well as low accuracy

and quality of the machined surface. The article deals with

technological opportunities for applying cylindrical car-

bide inserts (rods) as cutting tools for the finish turning of

plasma-sprayed products or coatings that have particularly

low machinability of cutting. It is shown that the use of

rods of a small diameter in the finishing operation makes it

possible to ensurе thе optimal geometric parameters of the

cutting part of the tool. At the same time, the forced rota-

tion of the rod allows us to considerably increase the tool

life period (up to 10–20 times or more) without reducing

the quality of the machined surface. The result of our work

is the design of the tool for turning surfaces using a rotary

cutting element
