Introduction

In mechanical engineering, shaped cutters have been widely used for processing shaped surfaces on turning machines and revolving machines, which are divided into prismatic and round in shape and design. By installation relative to the machined part, shaped cutters are divided into radial and tangential.

Shaped cutters are used to treat surfaces of a complex profile on lathe machines and less often on strict or loose machines in conditions of serial and mass production.

The advantages of shaped cutters: the accuracy of processing does not depend on the qualification of the workers, and the accuracy of processing can be IT 7, IT 14, and the roughness is 0.7-1.5 microns; high performance; long service life, since a large number of overflows; simple sharpening; possibility of wide application on automatic and semi-automatic machines.

Disadvantages of shaped cutters include: design complexity; complexity of manufacture; the need for accurate installation; high cost; different cutting conditions at edge cutting points. This results in different angles, cutting speeds, different cutting paths, and individual edges being worn out differently.
