Abstract

The relationship between the ring size and the friction coefficient was studied and the size effect in micro/meso-scale forming was determined. The kinetic viscosity of the three lubricants used were 2.6, 55, and 430 × 10 -6 sq m/sec. In the case of using lubricants, the friction coefficient became larger when the ring size was smaller. In the case of dry condition, the scatter of the friction coefficient became larger when the ring size was smaller. It was suggested that the large scatter of the coefficient was a size effect of friction in micro/meso-scale forming. This is an abstract of a paper presented at the World Tribology Congress (Kyoto, Japan 9/6-11/2009).
