流延成形是制造薄壁无缝钢管的一种有效的无切屑金属成形工艺。本文通过试验设计，建立了预测AA6082流动成型管材平均直径的回归模型。选择的工艺参数为轧辊的轴向进给量、芯棒的速度和轧辊的半径。在单辊流动成型机上用响应面方法研究了工艺参数对流动成型管材平均直径的影响。通过响应面方法建立的回归模型，在选定的工艺参数范围内成功地预测了AA6082流动成型管材的平均直径。研究发现，轧辊进给量和轧辊半径是影响成流AA6082成流管材平均直径的重要参数。WORDSAA6082合金，实验设计，平均直径，响应面方法。
Flow-forming is effective, chipless metal forming process used for the manufacture of thin walled seamless tubes. In the present paper, a regression model has been developed to predict mean diameter of AA6082 flow formed tubes by Design Of Experiments. The process parameters chosen for the present investigation are axial feed of the roller, speed of the mandrel, and roller radius. Experiments are performed on a single roller flow forming machine to study the effect of process parameters on mean diameter of flow formed tube employing response surface methodology (RSM). The regression model generated by response surface methodology successfully predicts the mean diameter of AA6082 flow formed tube within the range of selected process parameters. It is found that, roller feed and roller radius are significant parameters influencing the mean diameter of Flow-forming AA6082 flow formed tube.
