A Review on Optimization of Process parameter of Drilling Process for Hastelloy C 276
Keywords:
Circularity, Cutting Speed, Feed, Point angle, Super alloy, Surface roughnessAbstract
The growing need for miniaturization of systems necessitates the production of components with higher
dimensional accuracy. Nickel base super alloy Hastelloy C 276 have excellent mechanical and chemical properties at
low and intermediate temperature range, it has been widely used in petroleum, chemical processing and paper-puls
industries. Among all traditional machining processes, drilling is one of the most important metal cutting operations,
comprising 33% of all metal cutting operations. Dimensional accuracy (Surface roughness and Circularity) of drilled
hole is influenced by input conditions, material of the work piece or tool and condition of the machine. Among these
parameters cutting speed, feed and point angle have significantly affected the Surface roughness and Circularity.
