Abstract
Workpiece surface integrity is greatly affected by deflections within the grinding contact zone. A new relationship for the contact length between the grinding wheel and the surface of the workpiece is introduced based on contact mechanics. The model is based on the geometric contact length and also on the theory for cylinders in contact and the plastic deformation of the surface layer of the workpiece at the micro level of the grain contact. The new model suggests that the real contact length is typically 60% — 150% greater than the geometric contact length due to contact deflections, compared with 50% — 200% from measured values.
