“…The maximum draw wall angle ranged between 84.80° and 85.01° for a variable wall angled geometry with major diameter of 177 mm and a minor diameter of 142 mm. In the cross-sectional analysis (Figure 6) are revealed major thickness variations from 2.54 mm in region 1, 0.5 mm in region 5 and 2.2 mm in region 11 [13].…”

“…Multi-stage toolpath strategy is continuously optimized by research community to achieve formability and complexity in component geometry. Multi-stage incremental forming is used for high wall angles but is a concern because of the high thickness variation and necessitates the employment of trial and error methods used by a knowledgeable engineer [13].…”

Stretch forming of sheet metal materials is a highly required process in aerospace industry for manufacturing skin parts. Automation of some processes such as cutting, punching, forming, shearing and nesting in conventional manufacturing tends to combine these forming methods. Some researches are made on the formability of sheet metal materials obtained in incremental forming process with stretch forming and water jet incremental micro-forming with supporting dies. This paper is an attempt to review the newly researches made on optimization of manufacturing metal skin parts to achieve geometrical accuracy.

“…Salem et al presented an algorithm to predict and calculate the actual thickness by using the plane normal vector of the distorted element across the sheet [ 15 ]. Choi and Lee presented a mathematical prediction model of thickness distribution of the hybrid forming of ISMF and stretch forming based on the conventional sine law [ 16 ]. However, these methods have a great disadvantage in that they have a large number of calculations for the thickness prediction of parts with varied forming angles.…”

Incremental sheet metal forming characterized as increased flexibility and local plastic deformation is well suitable for low-production-run manufacturing and a new sample trial production of complex shapes. Thickness thinning is still an obstacle to the application of incremental forming. In this study, a novel mathematical algorithm based on a non-uniform rational B-spline (NURBS) surface was proposed and implemented which focuses on predicting and calculating the final thickness for arbitrary parts in incremental forming. In order to evaluate the validity of the proposed model, the finite element simulation and forming experiments of three kinds of parts, such as truncated cones, truncated pyramids and ellipsoid parts, were conducted. The thickness of theoretical prediction was compared with that of finite element simulation and experiment, and good agreements were obtained. The results show that the proposed model and the method are effective and robust for predicting the thickness of the formed parts in incremental sheet metal forming.

“…[9] have attempted heat assisted SPIF since the temperature helps in improving the formability of the material. In order to improve the precision and formability in SPIF, researchers employed different strategies like heating the sheet metal during forming process [10] and stretching forming in conjunction with conventional SPIF [11]. It was observed by Vahdani et al [10] in their investigation that the maximum depth of formed component was not improved in hot SPIF eventhough there is an improvement in formability of the DC01steel material.…”
