Single point incremental forming (SPIF) process has the capability to form small/medium-sized part generally used for rapid prototyping applications in automotive and non-automotive industry. Although considerable research has been conducted over the past decades on the formability of various aluminum alloy using SPIF process. This paper presents an investigation on the behavior of AA1200 H14 aluminum alloy by means of SPIF process. The formability of AA1200 H14 in terms of maximum formable wall angle has been evaluated using varying wall angle conical frustum (VWACF) profile. Taguchi method based design of experiment, analysis of variance (ANOVA), signal-to-noise ratio (S/N Ratio) have been employed to identify the significant parameters affecting formability. Utilizing the experimentally acquired results, the S/N ratio (dB) graphs have been drawn and identified the optimal parametric combination for maximizing the wall angle. Further, the formability of the parts has also been evaluated using forming limit curve. The changes in microstructure due to incremental deformation have been studied through scanning electron microscopic analysis.

单点增量成型（SPIF）工艺具有成型中小型零件的能力，该零件通常用于汽车和非汽车行业的快速成型应用。尽管在过去几十年中已经对使用SPIF工艺的各种铝合金的可成形性进行了大量研究。本文利用SPIF工艺研究了AA1200 H14铝合金的行为。AA1200 H14在最大可成形壁角方面的可成形性已使用不同的壁角圆锥形截头圆锥体（VWACF）轮廓进行了评估。基于Taguchi方法的实验设计，方差分析（ANOVA），信噪比（S / N比）已用于识别影响成形性的重要参数。利用实验获得的结果，绘制了信噪比（dB）图，并确定了用于最大化壁角的最佳参数组合。此外，还使用成形极限曲线评估了零件的可成形性。通过扫描电子显微镜分析研究了由于增量变形引起的微观结构的变化。
