Modelling and Analysis of Four Jaw Chuck

The work piece materials from initial stage to finished products that is effectively used in engineering applications successfully needs to be held firmly in machines for machining process. One such application is the lathe where work piece is held in chucks, if in case this holding device malfunctions or there is a loss in gripping force which may lead to the inefficient machining. Present work involves design and analysis of a four jaw chuck used in a small scale industry manufacturing cast iron double flange pipes for irrigation purpose. The work is concentrated on evaluating loss of gripping force in high speed power chucks due to centrifugal effect at the jaws and work piece material. A chuck is modelled in high end CAD tool and Simulated with initial gripping force using ANSYS tool and gripping force variation analysis is carried out. The FE analysis shows the successful evaluated results. In advent of sophisticated FEA tools such as ANSYS which has been extensively used in this dissertation work to design and development of a Four jaw chuck to hold the work-piece satisfying all and additional requirements.
