Parameter Optimization of MRR for EN31 Alloy. Conclusion

Turning is used to produce typically rotational and axis- symmetric part that have amenities such as threads, grooves, holes, contoured surfaces, tapers and many other applications of commercial importance. In this study, the experiments have been conducted on central lathe machine on EN31. The tool used for turning process is a cemented carbide coated insert of rectangular shape. From the experiment work it is concluded that the process parameters cutting speed, depth of cut and feed rate with different readings which are taken into consideration affects the metal removal rate. In this study there are two output variables are calculated which are surface roughness and metal removal rate. Metal removal in turning is the removal of metal from outer periphery of a cylindrical work piece to a specified dimension and to produce a smooth lustrous finish over the metal. In the beginning of experimental phase, Pilot experiments will be performed for preliminary study. The various parameters speed (275,440,620), feed (0.1, 0.2, 0.3) and depth of cut (0.5, 1.0, 1.5) their ranges and levels will be selected based on results of the pilot study. Suitable Technique for orthogonal arrays will be used for design of experiments after the pilot experiments. Based on the findings done, actual experimentation work will be designed and input machining parameters and their values are finalized. The results are experiments after the pilot experiments. Based on the findings done, astral experimentation work will be designed and input machining parameters and their values are finalized. The results are expected to show that the response variables (output parameters). So, the results which are obtained after experimentation and yeses and modeled for their application in manufacturing industry. The result shows that there is a significant increase in MRR with required combination of rotational speed, feed and depth of cut.
