Optimization of Drilling Parameters of JIG Boring Machine

In this project work an experimental study is being carried out for optimization of drilling process parameters of Jig boring machine to provide better tool life as well as high material removal rate (MRR). Taguchi method with L9 orthogonal array is used, for design of experiment and for analysis purpose grey relational analysis with fuzzy logic is used. Four main process parameters spindle speed, feed rate, depth of cut, and drill tool diameter are investigated in order to minimize thrust force and maximize MRR. Mild steel is used as work material and high speed steel twist drill as tool. Mild steel is well known extensively used engineering material in various industries such as steel making, structural, aerospace and aircraft industries. For the accomplishment of our project jig boring machine is used. Jig boring machine almost like semi CNC machine in terms of precision and accuracy in fact the jig borer's development helped advance machine tool technology toward later and CNC development.
