Original Abstract

The work deals with a machinability of Inconel® 718 construction material (hereafter referred to as “INC 718”). This chromium-nickel alloy has an austenitic structure, which in conjunction with its low thermal conductivity is one of the causes of a worse machinability. The aim of the work was to increase the productivity of the roughing turning process. There are more ways to improve the machinability of the INC 718, starting from the heat treatment of the material and ending with the application of process fluids. This work is based on real requirements of a company and therefore the possibilities of elimination of the worse machinability were limited by economic and technological aspects. For this reason, the main tool for increasing the productivity of the machining process was changing the material of the cutting tool and fine-tuning of the cutting conditions. In another part of the work, an evaluation of the experimentally determined force ratios of the reference and newly designed technology, which is the basis for the stress-strain analysis, have been made. The conclusion of the research highlights the newly designed process in terms of machining times and the volume of material achieved per unit of the cutting edge durability.
