Abstract
Optimization of machining parameters during end milling of super alloys using Grey based Taguchi method coupled with entropy measurement technique
Highlights
Nowadays, machining of nickel based super alloy parts is one of the big challenges in the manufacturing industry because of a huge demand for the products made by super alloys
The present paper focused on experimental study based on Taguchi’s method carried out to investigate the effect of parameters namely spindle speed, feed rate and depth of cut on burr height and thickness formed in end milling operation apart from this surface roughness along the slot examined
Discussion from results obtained through Taguchi experimental design and ANOVA reveals that Spindle speed and feed rate are most influential input factors to optimize burr height but for surface roughness depth of cut and feed rates are identified significant parameters to optimize surface roughness during end milling of nickel based super alloy
Summary
Nowadays, machining of nickel based super alloy parts is one of the big challenges in the manufacturing industry because of a huge demand for the products made by super alloys. The main feature of Fe, Ni & Co based super alloys due to its austenitic structure brings high ductility and work hardening, producing a gummy machining behavior. These are designed for high temperature applications remain strong at the generating temperatures while metal cutting operations, temperature stays always much high on the cutting edge. The present paper focused on experimental study based on Taguchi’s method carried out to investigate the effect of parameters namely spindle speed, feed rate and depth of cut on burr height and thickness formed in end milling operation apart from this surface roughness along the slot examined.
