Abstract

Turning of hardened materials with an advanced coated carbide insert has numerous advantages over the grinding process, e.g., reduced process cost, high material removal rate, and less environmental concern due to the elimination of the cutting fluid. Process parameters in conventional machining operations like cutting speed, feed, and depth of cut play the most crucial role behind the generation
of heat which also leads to microstructural changes, improved tool life, better surface finish, metal removal rate, and the most important is cutting force. In the present work, turning has been done on hardened AISI 4340 steel (42 HRC) using three different inserts of coated carbide (Titanium carbide coated groove-type SNMG-120408-PM, TiC-coated plain SNMA-120408-315/K15 and Al2O3 coated
groove SNMG-120408-THM) under the dry condition with a constant depth of cut. The cutting force has been analyzed under the different cutting conditions, chip profile, chatter, built-up edge, and chip reduction coefficient (CRC). A comparative study has been presented among different tool inserts to get desired performance such as material removal rate, tool wear, and profile of chips. In comparison with Al2O3 coated carbide insert the groove-type TiC-coated carbide inserts have shown better
machining results at higher cutting velocity and feed rate while turning cylindrical workpiece. No built-up edge has formed at TiC-coated carbide insert but SNMG-120408-THM insert results in a built-up edge chip. TiC-coated groove-type (SNMG-120408-PM) insert has shown longer tool life than the other two tool insert used in this work. Favorable chip formation, that is flat continuous-type
chip, is obtained at TiC-coated groove-type insert and may be recommended.
