Definition

Friction is defined, in its simplest form, as the tendency of two contacting surfaces to resist relative motion between them. In microforming processes, the effect of friction differs from its macroscale behavior, and it is magnified due to the small characteristic length scale of phenomena. This chapter tries to elucidate the nature of friction in microforming processes.

Scientific Fundamentals

Microforming refers to a collection of manufacturing processes that are employed in the fabrication of metallic microparts, i.e., parts that have at least two characteristic dimensions in the sub-millimeter range (Geiger et al. 2001; Vollertsen et al. 2004). The rapid advancement of miniaturization technology has created a strong demand for metallic microparts such as screws, connector pins, lead frames, pins for IC chips, contact springs, shafts, and gears, to name a few. These parts are usually fabricated by scaling...
