Performance of ISO P and ISO S carbide tools in hard turning of AISI 4140 under dry and MQL conditions

ABSTRACT The literature review shows few studies concerning the turning of hardened steels using carbide tools. A research in this case can provide a better understanding and an option of inserts with less cost than usually applied ceramic and CBN (cubic boron nitride) inserts. Thus, the objective i...

Hardened AISI 4140 steel coated carbide tools surface roughness tool nose wear ABSTRACT The literature review shows few studies concerning the turning of hardened steels using carbide tools. A research in this case can provide a better understanding and an option of inserts with less cost than usually applied ceramic and CBN (cubic boron nitride) inserts. Thus, the objective is to investigate the tool-life of ISO P and ISO S grade coated carbide inserts and average roughness (Ra) of the machined surface generated with these tools in the hard turning of AISI 4140 steel under dry and minimum-quantity of lubrication (MQL) conditions. Comparing the ISO P and ISO S grades tool life in two different cutting speed levels (60 and 120 m/min), the higher cutting speed generated the lowest Ra values. Relating the lubri-cooling conditions, dry turning resulted in lower Ra values. When the tool nose wear does not change during the passes, the Ra remains constant. In addition, ISO S grade coated carbide insert has shown a possibility for this hard turning due to the low tool nose wear at a relatively high cutting speed.info:eu-repo/semantics/openAccessUniversidad de Tarapacá.Ingeniare.
