【 摘 要 】

The present study has found that during the integrated processing after the diamond smoothing, in the surface-hardened sample a cold-worked layer 0.010.02 mm in thickness, the microhardness value of which reaches 868 HV, is formed. The intensity of compressive stresses on the part surface increases to στ= -678 MPa. The analysis of the experimental data has shown the relationship between the parameter Ra and the processing modes that can be used during diamond smoothing, based on the high performance and the desired surface roughness. It has been found that the minimum value of roughness Ra = 0.18±0.08 μm is reliably achieved by smoothing processing when the smoothing force Pyranges from 100 N to 150 N.
