The effect of forming parameters during the incremental sheet forming process (ISF) was studied for a circular shape sheet part. ISF is known as a rapid prototyping method to produce sheet metal parts in a batch production series. ISF has found to be useful and advantageous which increases its application in industry. A CNC lathe machine was used in this study because it was easily programmed t...

Laser forming is a flexible sheet metal forming technique using laser induced thermal distortion to shape sheet metal without hard tooling or external forces. Concave laser forming can be readily achieved, while convex forming could be done under buckling mechanism but whether convex forming is actually obtained heavily depends on the initial strain/stress state of the sheet. A new laser-scanni...

Abstract Laser forming is a flexible sheet metal forming technique using laser-induced thermal deformation to shape sheet metal without hard tooling or external forces. Concave laser forming can be readily achieved, while convex forming may occur through buckling, but the buckling direction heavily depends on the sheet surface and pre-strain condition. A new laser scanning scheme is postulated,...

Laser bending is an advanced process in sheet metal forming in which a laser heat source is used to shape the metal sheet. In this paper, temperature distribution in a mild steel sheet metal is investigated numerically and experimentally. Laser heat source is applied through curved paths in square sheet metal parts. Finite element (FE) simulation is performed with the ABAQUS/CAE standard softwa...

shape error due to elastic recovery of formed part in unloading known as springback, is one of the most important problems of tool design in sheet metal forming processes. many researches have been performed for proposing an efficient method to decrease or compensate springback error in sheet forming processes. these methods are usually based on iterative finite element algorithms. in this pape...
