Abstract


Objective: Effect of machining parameter (Speed, Feed, Depth of cut) on output machine responses (Material Removal Rate (MRR), Machining time, Tool wear and Surface roughness) is studied using Taguchi method. Methods/Analysis: Experiment was conducted on work piece material namely EN8 Steel. For cutting speed, feed rate, Depth Of Cut (DOC). Orthogonal array L9 was created using MINITAB-16. For different combination, the respective surface roughness average was obtained using surface roughness tester and Taguchi analysis to understand the relation between the machining parameters and output responses. Findings: Feed rate is the important factor in obtaining the optimum surface finish of EN8 than other parameters during turning and also scarps can be reduced gradually. Novelty/Improvement: With the help of Taguchi method, Noise factor and control factor are identified which are highly useful in screening the critical parameters for optimum surface finish.
