The aim of this work is to evaluate the performance of a newly developed multi-walled carbon nanotube (MWCNT) reinforced alumina inserts. Machining of 'difficult to machine' materials requires harder cutting tool. So, for machining hardened materials, reinforced ceramic inserts with enhanced mechanical properties like fracture toughness and hardness are used. In this research work, multi-walled carbon nanotube reinforced alumina nanocomposite is used as a cutting tool that has Vicker's hardness value of 20GPa and fracture toughness of 6.43 MPa m1/2. Machining of AISI 4340 steel rod is done under dry environment. Progress of tool wear at two cutting conditions is evaluated. Tool life of the newly developed insert may be improved by employing suitable machining environment, proper tool geometry and parameters during production of the MWCNT reinforced alumina insert.Keywords

This paper concerns with machinability studies in finish turning of AISI 52100 steel using various tool inserts. This steel is applied in different structural and other industrial applications. Turning tests are performed under different cutting velocity and feed with plain, narrow groove and wide groove coated carbide tool inserts. Using these diverse conditions, types of chips formed, cutting force, etc., were noted, and machinability of the tool-work combine under different conditions is explored, so that some conditions can be found out at which good machinability can be achieved. Although narrow or wide groove chip breakers are used, chip breaking is not much observed in general. Fair machinability is observed while turning using all the three types of inserts. However, fairly good tool performance is obtained when plain carbide insert is employed at higher cutting velocities of 174 and 274 m/min at the chosen feed even in dry condition.Keywords

Cutting fluids play a significant part of metal working industries. They are broadly utilized due to their capacity to diminish tool wearing, cutting force, temperature, etc. to improve workpiece surface quality. The present work focuses on the machinability study of hard AISI 4340 steel using eco-friendly cutting fluids. Turning experiments are carried out using coated carbide inserts through Small Quantity Lubrication (SQL) under different cutting velocities and feed. Dry, rice bran oil-based solution and alkaline solution are chosen to be the environmental conditions. Under different machining conditions, types of chips, cutting force, surface roughness, etc. are noted. Full factorial type response surface methodology is used to decide on experimental runs. Tool wear tests are also performed under wet conditions. Cutting force is observed to be significantly reduced in a chosen wet environment under some cutting conditions. Rice bran oil-based emulsifier is found to perform better than alkaline solution to increase tool life.Keywords
