Lubricant Applying Effect in Ductile Metal Cutting

Depth of Cut and Cutting Speed Effects and Mechanism

Abstract

The depth of cut and cutting speed effects were examined In order to clarify the precise lubricant applying effect The experimental results indicated that the microvickers hardness distribution in the region to be cut and the cutting speed markedly controlled reduction percentages in the cutting forces. It is concluded that the lubricant applied to the pre-cut surface reduced friction in the lamella structure, which results in easier shear deformation under high normal stress at the shear plane.
