A TOOL FOR FINISH TURNING OF PLASMA-SPRAYED MATERIALS

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
