Optimization of Lathe Parameters for Minimum Surface Roughness and Maximum MRR

Material handling systems are commonly used in almost all the industries in all over the world. It is an art and science involving moving, packaging and storing of substances in various forms. This paper contains design of low cost bale trolley used for cotton bale handling. The Bajaj steel industry has manufactured cotton pressing machine 15 BP4818, for that they need to design new trolley according to the size of bale. They have previously designed bale trolley for another press machine (for BP5421) which is not suitable for this new pressing machine (15 BP4818). As more and heavy material was used in previous design which was leading in increasing cost of the bale trolley. Requirement is to improve previous design and to reduce weight according to cotton bale size (which is 175 kg). This paper theologies with the Taguchi technique for the optimization of lathe parameters on a cylindrical round workpiece of EN19 steel. In industry main objective is to have a good quality surface or to get a maximum material removal rate. The three significant parameters of lathe which are used are speed, feed and depth of cut. The number of experiments has been carried out using Taguchi's orthogonal array in the design of experiments (DOE).Analysis of Variance is used to identify the effects of parameters on the workpiece. Roughness values are measured using a surface roughness meter. From experimental results the mathematical models were generated for the parameters.
