Influence of clamping force on the machined surface in abrasive finishing



On the basis of the Preston hypothesis, it is possible to establish variation of the clamping force in the course of machining such that the contact pressure is stabilized and the productivity is increased. In the finishing of planes with different initial microrelief, the time dependence of the contact area is found to be exponential. The assumptions made in the analysis are experimentally verified in abrasive finishing on a Rastr 220 machine. With exponential variation in the force — that is, variation analogous to that of the contact area in abrasive finishing—the productivity is increased by a factor of 2.5–3.
