Comparative Studies on Machinability of MCLA Steels EN19 and EN24 Using Taguchi Optimization Techniques

Medium carbon low Alloy steels are commonly used for manufacturing of automotive components such as gears, spindle, shafts and aerospace components etc. In order to improve the mechanical properties of steel, forging and annealing operations are carried out. Machinability and surface roughness test was carried in order to find the optimum parameters of the EN Steels. Machinability is the ability of material, with ease of removal. Machining of material effects on the Tool Forces, power consumption and Surface Roughness. The present work focuses on Comparative Studies on Machinability of Forged and annealed EN19 and EN24 MCLA Steels, using Taguchi Optimization Technique. For machinability test, the Design the experiments is carried according to Taguchi L9 orthogonal array. Machinability Test is performed on the centre lathe, and the parameters studied are the cutting Speed, Feed and Depth of Cut. Also, the surface roughness is carried for the machinability samples to optimize the parameters for surface roughness using Taguchi's experiment.
