Abstract

A fixture is mainly a work holding or support device used in the manufacturing industry. Fixture is used to securely locate position in specific location or orientation and support the work. Ensuring that all parts produced using the fixture will maintain conformity and interchange ability. Locating and supporting areas must usually be large and very sturdy in order to accommodate welding operation; strong clamps are also a requirement. The body of a hood consists of various plates that have to be welded to each other with a specific tolerance and weld quality. The material used in the manufacture of different parts of the body of a hood assembly is mild steel which is one of the most commonly used materials in the field of fabrication. All the welding processes are carried out by welding to ensure quality of the weld is as per the requirement. The fixture is designed and manufactured and it is checked for dimension conformance based on the CMM report. After testing and validation it is moved to production for regular production.
