Title

Experimental investigation of effect of PVD , CVD and CERAMIC tool inserts in turning of hardened EN 19 / AISI 4140 for optimization of surface roughness

Abstract

The experimental study evaluates the influence of different turning parameters on quality of surface produced on CNC turning of high performance EN series material. Experiments were conducted with the combination of various input parameters for turning round bar of AISI 4140 material and hardened at 35 – 40 HRC. The experimental runs have been carried out with proper variation in the levels of input turning parameters. Three machining parameters are chosen as process parameters: type of Tool Insert, nose radius of tool insert and feed rate. The levels and ranges were determined from pilot experimentation results.The experimentation plan is designed using full factorial L27 Orthogonal Array (OA) using Minitab-15 statistical software. Optimum values of input parameters for desired performance characteristics are obtained by full factorial design of experiment. the optimal and obtained results are also verified with the help of confirmation experiments The results with full factorial design is discussed analytically to find the significant and sub significant turning parameters affecting the surface roughness. For the analysis and results, statistical technique of ANOVA is used. ANOVA for data means for turning with L27 DOE shows that surface finish is most significantly affected by feed rate and subsequently by tool nose radius and type of insert. The analysis of 33 full factorial DOE shows that surface finish is most significantly affected by of interaction among tool nose radius and feed rate.
