Two-point incremental forming method is considered a modern technique for manufacturing shell parts. The presence of bottom punch during the process makes this technique far more complex than its conventional counterpart i.e. single-point incremental forming method. Thus, the numerical simulation of this method is an essential task, which leads to the reduction of trial/error costs, predicts th...

ultrasonic vibration assisted single point incremental forming (uvaspif) process is an attractive and adaptive method in which a sheet metal is gradually and locally formed by a vibrating hemispherical-head tool. the ultrasonic excitation of forming tool reduces the average of vertical component of forming force and spring-back rate of the formed sample. the spring-back phenomenon is one of the...

Single point incremental sheet metal forming is a sheet metal forming process that forms products without the complex dies and tools with low cost. In this study, the incremental sheet metal forming process has been experimentally investigated on the explosively-welded Al/Cu bimetal sheets. Also, the effects of process parameters, such as arrangement of layer`s bimetal, tool diameter and tool p...

In this work, incremental sheet forming of a complicated shape is investigated experimentally. Two point incremental forming with negative and positive dies are employed for manufacturing of a complicated shape with positive and negative truncated cones. The material is aluminum alloy 3105 with a thickness of 1 mm. The effects of process parameters such as sequence of positive and negative form...

Single point incremental sheet forming (SPISF) has demonstrated significant potential to form complex sheet metal parts without using component-specific tools and is suitable for fabricating low-volume functional sheet metal parts economically. In the SPIF process, a ball nose tool moves along a predefined tool path to form the sheet. This work aims to optimize the formability and forming force...

Abstract The mechanical properties and the operating life of a formed component are highly dependent on residual stress state. There is always high magnitude stresses in components by incremental sheet forming (ISF) due to localized deformation mechanism. Hence, thorough understanding generation ISF necessary. This study investigates mechanism for two process variants ISF, i.e., Single Point In...
