Problems of mechanical processing of parts from austenitic steel 110g13l

Abstract

This article presents an analysis of scientific studies devoted to the machining of 110G13L steel. It was identified that research focused on investigating and developing machining methods for 110G13L steel is practically absent. In industrial practice, cutting inserts from foreign manufacturers are predominantly used for machining this steel. Nevertheless, the problem of excessive cutting tool consumption due to rapid wear, chipping, and breakage remains unresolved and increases the production cost of components made from 110G13L steel. The results of the experimental study confirmed the feasibility of applying thermo-friction milling with pulsed cooling for machining 110G13L steel. When machining under optimal cutting conditions, the achieved surface roughness reached only Rz ≤ 10 μm. However, it was revealed that there is an issue related to ensuring the required surface quality and chip breaking during machining. It is proposed to develop a combined milling method for difficult-to-machine materials, where the cutting mechanism is based on both thermo-friction and conventional cutting. This research was funded by the Committee on Science of the Ministry of Science and Higher Education of the Republic of Kazakhstan under grant № AP26199283, “Development of a combined method for processing hard-to-machine materials”.
