摘　　要：设计一种微束等离子选区熔化实验平台,利用SolidWorks软件对各零部件进行三维建模与虚拟装配,实现直角坐标系机器人结构的实验平台实物搭建.在不同工艺参数下,开展单道、单层微束等离子选区熔化实验,采用多项式回归对成形道宽度进行拟合.结果表明,成形电流、成形速度与成形宽度呈正相关分布.在多层金属熔覆实验中,对于厚度为2.40 mm的金属薄板而言,最佳参数为12.0 A的电流、2.0 mm·s~(-1)的扫描速度和20%的搭接率.最终得到的多层金属成形效果较好,证实微束等离子选区熔化工艺的可行性.A microbeam plasma selective melting experimental platform was designed.SolidWorks software was used to conduct 3D modeling and virtual assembly of each component,realizing physical construction of the cartesian robot structure experimental platform.Under different process parameters,single⁃path single⁃layer microbeam plasma selective melting experiments were conducted.Polynomial regression was used to fit the formed path width.The results show that the forming current,speed,and width are positively correlated.In the multi⁃layer metal cladding experiment,the best parameters for a 2.40 mm metal sheet were obtained with a current of 12.0 A,a scanning speed of 2.0 mm·s-1,and an overlap rate of 20%.The forming results of the final multi⁃layer metal is good,proving the feasibility of microbeam plasma selective melting technology.
