Abstract: This Project presents the Design of Machining Fixture for Gas Turbine Rotor Blade for Machining on VMC (Vertical Machining Centre). Fixture Design consists of High product rate, low manufacturing operation cost. The fixture should be designed in such-away that part/product change overtime is very less. The report consists of study of input data from customers like Part drawing and Assembly drawing. The fixture design begins with part modeling, Machining and Analysis of various parts in the fixture assembly using AutoCAD and Solid works, for a analysis COSMOS Software package is used. The actual design begins with study details of project proposal summary from customer. After that machining fixture concept is done. Locating and clamping points are decided. This also includes accessibility, loading and unloading sequence of parts, required material for this fixture is selected, and Fixture is designed at SRI VENKATESWARA MECHANICAL AND ELECTRICALENGINEERING INDUSTRIES, Hyderabad using Industrial application standards. Locating accuracy and machined part quality tested and found that the fixture is as good as any dedicated fixture in production.
