This project is analysing the nimonic 80 properties by using cryogenic treated tool and untreated tool (Drill bit). It is a conventional machining process (Drilling) for a tool and work piece have a direct contact. A tool (4mm) drill bit is used for the machining process. A tungsten carbide tool (drill bit) 4mm is used to make a drill on the work piece and posterior of tool can be treated in cryogenic process, then make another drill in work piece. Finally all the dimension test, circularity test and hardness test has been taken for both tool and work piece. Nimonic 80 is a super nickel based alloy, and it has a low creep and high temperature with stand character. The composition of nimonic 80 (50% nickel, 20% chromium, titanium and aluminium are additives). Because of the presence chromium metal, it won’t get corrode during cold condition based machining process. Cryogenic treatment is a process to study the tool (or) work piece character and properties change under the temperature (-180oc). Mostly it is used to preserve food materials and also used as a fuel for the Aerospace vehicle.
