Abstract

A new compression-twist type friction testing machine has been developed to simulate the frictional conditions prevailing in metal forming. Twin indenter tools with different sliding length were used and mineral oils were tested under frictional sliding between mild steel and a tool steel. New indexes of boundary lubricity, oil-film strength, and anti-galling ability are proposed to evaluate lubricant performance.
