Experimental study on energy partition of polishing aero-engine blades with abrasive cloth wheel

Abstract

Grinding or polishing temperature has an important influence on the life and working performance of parts. The temperature distribution in grinding process is not only related to the total heat generated but also related to the energy partition. In this paper, the polishing force and polishing temperature were measured in the process of polishing aero-engine blades, and the contact arc lengths were calculated indirectly. Thereby, the energy partition was obtained by calculation. It is shown that the correlations between the energy partition and the spindle speed are negative; the correlations between the energy partition and compression depth are also negative; the energy partition increases relative to the increase of feed speed, and the energy partition decreases to a constant pace with the increase of size of abrasive cloth wheel gradually. An energy partition model was fitted, and the model was verified by experiments.
