Experimental Analysis of Cutting Force of Magnetically Molded Specimens Observed Under Different Conditions of Shot Size and Magnetic Field

Magnetic molding is a molding process which can serve as an environmental friendly casting technique and has the potential to provide a solution to many of the manufacturing and environmental problems faced by the metal casting industry today. In this work a solid pattern is used. The pattern is backed up by steel shots, which are consolidated by magnetic field. In this work castings were made with 4824, 7236, 8442 ampere turns under varying shot sizes of 40μ, 80μ and 100μ. Trials on machining were carried out on the castings obtained, under eight machining conditions by varying cutting speed, feed rate and depth of cut. The variation in the cutting force with respect to steel shot size under a constant magnetic field was determined for each of the machining conditions. The results show that shot size has strong influence on the cutting force in magnetic molding.
