Lubricating Action of Cutting Fluids

An experimental investigation into the lubricating action of carbon tetrachloride when cutting copper for a carefully selected range of controlled conditions has enabled the formulation of a fundamental specification for a cutting lubricant. In this specification, a new proposal has been made concerning the penetration of the fluid to the contact regions of the cutting tool. The penetration rate of a neat chemical compound chosen on the basis of this fundamental specification appears to behave as predicted when applied during the machining of copper.
