Abstract: The present work deals with the design of Gear Fixtures for L200 and H250 CNC Gear Hobbing Machines. The task on hand was to design fixture for the components, namely Reduction ideal gear and 4t1i and 3rd speed gear for gear box used in HMT Tractors. Fixture design and selection starts with the component and the manufacturing operation to be performed. The criteria for this design process are accuracy, positive location, repeatability, production rate and importantly, the reliability under the action of the cutting force and shear experienced. The clamping forces and construction easiness have also been accounted for design. The proposed design was then checked for safety under the action of the involved stresses. The calculations of the cutting force are shown and proved that the forces at various vital points in the design are well below safety limits. Expert analysts then approved the design.
