N. Ulianov Chuvash State University, 15 Moskovsky Prospekt, Cheboksary, 428015, Russian Federation Abstract At present, a special place among the manufactured products is occupied by parts made of corrosion-resistant materials, for example, corrosion-resistant steel of the following content: 0.12% C, 18% Cr, 10% Ni, 1% Ti. Such materials are used in mechanical engineering, aircraft construction, food and other industries. It has high requirements for the quality of the surface layer. The quality indicators include, among other things, the roughness of the treated surface. The required surface roughness is achieved during finishing operations. Corrosion-resistant steels have high physical and mechanical properties and are classified as difficult to machine materials. In this regard, there are problems with its processing and the achievement of the required roughness of the surface layer. One of the effective methods for processing difficult-to-machine materials is the method of electrochemical grinding with a diamond tool on a metal bond. It has several advantages over traditional finishing methods. The aim of the work is to determine the effect of cutting modes on the surface roughness during electrochemical grinding of corrosion-resistant steel. In the course of the work, a matrix for planning experiments is drawn up and experiments are carried out to identify the effect of cutting modes on the roughness of the processed surface. The values of cutting conditions at which the roughness of the machined surface is minimal are established.
