Confidence of accuracy parameters and quality of the surface layer at receipt of deep groove in details of the combustion chamber of a gas turbine engines by method of abrasive electrochemical grinding

Abstract

The work proposes a promising method of abrasive electrochemical grinding with periodic cleaning of the cutting tool when receiving deep, narrow, extended grooves in the parts the segment of the combustion chamber of a gas turbine engine from a heat-resistant intermetallic alloy. Issues of ensuring the quality of the surface layer, increasing fatigue strength and geometric accuracy are relevant and are closely related to ensuring the cutting properties of the working tool. A comparative analysis of the samples obtained by the method of abrasive electrochemical grinding without periodic cleaning and with simultaneous periodic cleaning of the abrasive wheel was carried out.
