摘要：

采用2A12铝合金作为试验材料，以成形极限角作为衡量工艺参数对板料单点渐进成形的成形能力影响的标准。试验中研究对成形能力影响的工艺参数有：工具头半径、加工步长、进给速度和主轴转速。采用正交试验法对板料在单点渐进成形中的成形极限进行研究。试验结果表明，对板料单点渐进成形的成形能力影响最大的因素是加工步长，其次是进给速度、主轴转速和工具头半径。

2A12 sheet metal was employed as the experimental material, used maximum wall angle as a formability representative, the variation in the process parameters affecting the formability in single point incremental forming was investigated. The process parameters affecting the formability were studied, such as tool radius, step size, federate and spindle speed. Sheet metal forming limit in single\|point incremental forming was studied based on orthogonal design. The experiment results show that step size in the forming process has a considerable influence, and the others in sequence are the feeding rate, spindle speed and tool radius.
