Hs. Qi et al., CONTACT LENGTH IN GRINDING .2. EVALUATION OF CONTACT LENGTH MODELS, Proceedings of the Institution of Mechanical Engineers, Part J, Journal of engineering tribology, 211(J1), 1997, pp. 77-85
A non-linear curve fit method was used to identify model parameters fo
r the prediction of contact length in grinding. The evaluation shows t
hat the model based on a surface roughness factor demonstrates a high
degree of correlation with experimental trends and behaviour. It was f
ound that the roughness parameter R-f is insensitive to depth of cut,
speed ratio and material hardness, but is sensitive to the wheel-workp
iece material combinations and whether grinding is conducted with or w
ithout coolant.
