Abstract (English):
The investigation results of technological conditions impact at multiaxes deep grinding upon quality of titanium alloy blade surface layer in the compressors of gas turbine engines (GTE) are presented. The grinding mode impact upon a surface and a value of residual stresses in a surface layer of blades is defined and also conditions for defect occurrence as burns on blade surfaces under machining are detected.
