Abstract

The literature review shows few studies concerning the turning of hardened steels using carbide tools. This study investigates the tool-life of ISO P and ISO S grade coated carbide inserts and average roughness (Ra) of the machined surface during the hard turning of AISI 4140 steel under dry and minimum-quantity lubrication (MQL) conditions. The higher cutting speed generated lower Ra values, and dry turning resulted in lower Ra compared to MQL. The ISO S grade coated carbide insert showed low tool nose wear at a relatively high cutting speed.
