【摘要】:基于KUKA机器人搭建铝合金CMT增材制造系统,在Robotmaster离线编程软件中建立虚拟机器人工作场景,对成形零件进行分层、轨迹规划、模拟仿真及程序生成,使用CMT冷金属过渡焊接工艺进行铝合金零件增材制造试验,利用二次回归通用旋转组合方法设计试验,对熔敷工艺参数(送丝速度、喷嘴高度、焊接速度)与熔敷层宽度、高度的成形规律进行研究,建立熔敷层尺寸的预测模型。通过铝合金零件成形试验对模型精度进行验证,发现该模型预测效果好,成形铝合金零件精度高。
[Abstract]:Based on the KUKA robot, the aluminum alloy CMT material increasing manufacturing system is built, and the virtual robot working scene is established in the off-line programming software of the robot master. The forming parts are stratified, trajectory planning, simulation and program generation. CMT cold metal transition welding process was used to manufacture aluminum alloy parts. The secondary regression general rotation combination method was used to design the experiment. The parameters (wire feeding speed, nozzle height, welding speed) and the width of the coating layer were analyzed. The forming law of height was studied, and the prediction model of coating size was established. The precision of the model is verified by the forming test of aluminum alloy parts. It is found that the model has good prediction effect and high precision of forming aluminum alloy parts.
