摘要
为了研究工艺参数对增材摩擦搅拌沉积工艺的影响,基于摩擦搅拌工艺原理自主研制了金属增材制造实验装置.在主轴转速 420 r/min、进给速度 72 mm/min、移动速度 72 mm/min、增材层厚 3 mm、启动时间 50s的工艺条件下,对 6061铝合金进行了单层和双层增材沉积初步实验.结果表明,该实验装置实现了良好的铝合金固相增材,可用于增材制造相关领域的科学研究和实验教学工作.
Abstract
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.
