CUTTING TOOL EQUIPMENT OF TURNING SURFACES OF A COMPLEX PROFILE

Abstract

The article shows the technological problems associated with turning by the indexable inserts parts with a complex profile, formed by a combination of rotational surfaces with the elements of the rupture – various grooves, holes, slots, recesses, etc., when cutting with difficulty creating the accuracy and quality. In the course of turning discontinuous surfaces, the relationship between the cutting element and the workpiece surface is es-tablished, as well as the design features of the tools used. The article shows the ways to improve the tool equipment of turning surfaces of a complex profile concerning the pres-ervation of the tool life during the period of cutting parts on the one hand and the need to obtain a quality of the products produced on the other hand.
