Modelling, Simulation and Analysis of Gripping Force Loss in High Speed Power Chuck

AbstractThe 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. Now days in CNC machines the automated chucks are used to hold the work piece to successfully be machined, if in case this holding device malfunctions or there is a loss in gripping force which may lead to the inefficient machining. The present work is concentrated on evaluating the loss of gripping force in high speed power chucks due to centrifugal effect at the jaws and work piece material. A standard power chuck is modelled in high end cad tool like CATIA R20V5 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
