【摘要】:基于KUKA機器人搭建鋁合金CMT增材制造系統(tǒng),在Robotmaster離線編程軟件中建立虛擬機器人工作場景,對成形零件進行分層、軌跡規(guī)劃、模擬仿真及程序生成,使用CMT冷金屬過渡焊接工藝進行鋁合金零件增材制造試驗,利用二次回歸通用旋轉(zhuǎn)組合方法設(shè)計試驗,對熔敷工藝參數(shù)(送絲速度、噴嘴高度、焊接速度)與熔敷層寬度、高度的成形規(guī)律進行研究,建立熔敷層尺寸的預測模型。通過鋁合金零件成形試驗對模型精度進行驗證,發(fā)現(xiàn)該模型預測效果好,成形鋁合金零件精度高。
[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.
