Keywords:
Metal-polymer-metal laminate, Spring back, Full-factorial design, Statistical design of experimentAbstract
Spring back is one of the parameter which affects the accuracy and success of the bending process. In the present work, the spring back behavior of the aluminum polymer laminate is studied by the three point bending process by varying three parameters viz. core to skin thickness ratio (Tc/Ts), the speed of bending (N) and punch radius (rp). Amount of spring back and peak bending load was measured with each combination of process parameters Tc/Ts, N and rp. The experimental work has been carried out on the Tensometer having load measurement capacity as two tone. The levels of the input parameters are decided by performing screening experiment. The experimental results have been analyzed using full factorial statistical experimental design technique.
