    Abstract
  • In order to explore the influence of dressing process parameters, such as dressing depth ad, axial feed speed fd and dressing speed ratio qd, on the grinding surface integrity of 18CrNiMo7-6 gear steel, orthogonal experiments were conducted for shaping dressing process using ceramic bonded chrome corundum grinding wheels with resin bonded diamond disc wheels, bronze bonded diamond disc wheels and single particle diamond pens, respectively. The cross grinding test of 18CrNiMo7-6 gear steel was carried out with a chrome corundum wheel after dressing. The results show that the surface roughness Ra of the grinding process increased with the increase of the dressing process parameters, and residual compressive stresses were more easily obtained on the grinding surface. The comprehensive evaluation of the grinding surface integrity for the three dressing tools, using a normalized dimensionless method, shows that the grinding surface integrity of the bronze-bonded diamond disc wheel dressing is better than the other two dressing methods. Furthermore, the grinding surface integrity is better when ad=4 μm, fd=100 mm/min, and qd=0.3.
