Evaluation of the Quality Parameters of the Surface Layer of Parts After Machining with Plasma Heating

This study aims to improve the technology for processing parts from hard-to-work materials, to study and substantiate the parameters of the plasma-assisted machining processing of surfaces of alloy steel parts to increase processing productivity and ensure the necessary quality of surface layers. Theoretical studies consist in determining the parameters of the thermal field of a workpiece during milling and turning with plasma heating. Experimental studies are based on a study of the interrelationship of the main indicators of machining with factors of preliminary plasma heating allowance.
