The paper deals with the new, original model of energy partition in dry constant-load steel grinding. Experimental setup, experiment conditions and analyses were shown and discussed in this article. New findings are presented for energy flux distribution and energy partition ratios. Energy partition ratios, determined during experiments were compared with theoretical values for constant, maximum energy carried away by the grinding chips ecc, approximately 6 J/mm3. Original model, based on grinding chips stream temperature measurements was used for chips energy partition ratio Rc evaluation. Measurements were made using high-class testing equipment, e.g. Kistler 9257B dynamometer and Minolta-Land Cyclops optical pyrometer. A case study based on constant-load grinding C45 (AISI 1045) with alumina grinding wheels is used to illustrate the variability of energy carried away by the grinding chips. Developed model of grinding energy partition can be useful for on-line grinding control systems, especially for low specific grinding energy and high efficiency grinding processes.
