Experimental studies on the study of shrinkage shrinkage and frictional force on the front surface of a cutter when turning workpieces of steel grade 45

Abstract

In the process of machining, depending on the properties of the material being processed, the
geometrical parameters of the tool and the size of the cutting mode elements, various chips can be
formed. In appearance, there can be an infinite number, which is divided into three main types:
chipping chips, drainage chips and shavings. Technical re-equipment of machine-building
production involves an increase in the productivity of the metal cutting process, improving the
quality of the machined surface, optimal processing modes and methods of controlling the cutting
process with a tool. The successful solution of all these issues is connected with the further
development of the science of metal cutting.
The aim of the work is to determine the normal and tangential stresses on the front surface
of the tool. The method of performing the work includes experimental and theoretical determination
of the parameters at various stages of the study.
