【 摘 要 】

AISI 4340 steel is an alloy steel of nickel, molybdenum, and chromium with medium carbon content. It is known for its high toughness and the ability of further enhancement in strength by applying heat treatment condition. It is used in aircraft landing gear, oil and gas drilling, automobile industry and general engineering industries to manufacture heavy duty gears, shafts, pins, spindles, couplings, chucks etc. As it is a hard to machine material so many researchers are taking keen interest to study the effects of different machining environments and machining aspects on the machining performance of 4340-grade steel. The present paper presents a comprehensive review on important aspects associated to machining of 4340 grade steel using different cooling environments and cutting tools. Experimental and theoretical observations for tool wear, surface roughness, tool life, residual stress, machining force and cutting temperature using different types of cutting inserts under distinguish cooling environments are also been discussed.
