This paper presents the findings of an experimental investigation into the effects of cutting speed, feed rate, depth of cut, nose radius and cutting environment in CNC turning of AISI P-20 tool steel.
Experiments were performed based on L18 standard orthogonal array design by five input process parameters, namely cutting speed, feed per tooth, radial depth of cut, cutting time and cutting environment.
The six parameters i.e. tool nose radius, tool rake angle, feed rate, cutting speed, cutting environment (dry, wet and cooled) and depth of cut are varied to investigate their effect on output responses.
"You don't protect the environment by cutting environment programs".
Influence of various cutting parameters, cutting environment, coating, wear and edge geometry of cutting tools on different features of surface integrity has been critically explained.
The performance of the different tools thus manufactured was evaluated by carrying out suitable turning experiments on cylindrical Ti6Al4V work material under dry cutting environment.
After optimization it was found that vc = 90 m/min, f = 0.1 mm/rev, ap = 1.5 mm and MQL cutting environment simultaneously optimized this turning system.
Based on grey relational analysis, the optimal setting of process parameters were identified and analysis of variance indicated that cutting time, feed per tooth and cutting environment are the most influential parameters on machining performances.
The present study investigates the machining performance of coatings deposited by cathode arc evaporation (CAE) and DC reactive magnetron sputtering (DCRMS) process with different structures and deposition layers on Al2O3/TiCN ceramic inserts in turning of hardened steel under dry cutting environment.
The present work deals with a comparative study on flank wear, surface roughness, tool life, volume of chip removal and economical feasibility in turning high carbon high chromium AISI D2 steel with multilayer MTCVD coated [TiN/TiCN/Al2O3/TiN] and uncoated carbide inserts under dry cutting environment.
