Development of Metal Additive Manufacturing Experimental Device Based on Friction Stirring
In order to study the influence of process parameters on the friction stir deposition additive process and enhance the understanding of additive manufacturing technology among students majoring in manufacturing and materials,an additive friction stir deposition(AFSD)experimental device was independently designed based on the principle of friction stir process.Under the process conditions of spindle speed of 420 r/min,feed speed of 72 mm/min,moving speed of 72 mm/min,additive layer thickness of 3 mm,and start-up time of 50 s,preliminary experiments on single-layer and double-layer additive deposition of 6061 aluminum alloy were carried out.The results show that the self-made AFSD experimental device achieves good solid-phase additive of aluminum alloy and can be used for scientific research and experimental practice teaching in the field of additive manufacturing technology.
