In this work, cold bulge forming of an Aluminium-Magnesium (Al-Mg) sheet with a solid bulging medium is performed experimentally and numerically.  Mechanical properties and thickness variations of Al-Mg sheet are evaluated before and after the forming process.  The results indicated that the Al-Mg sheet has taken the desired shape without necking using the cold bulge forming process.  Also, the...

This paper describes an application of data mining, namely classification, with respect to 3-D surface analysis. More specifically in the context of sheet metal forming, especially Asymmetric Incremental Sheet Forming (AISF). The issue with sheet metal forming processes is that their application results in springback, which means that the resulting shape is not necessarily the desired shape. Er...

the aim of this paper is to develop a systematic method to analyze the effects of forming parameters on the quality of part formability and determine the optimal combination of the forming parameters for the sheet hydroforming process. in this paper, the effects of four important process parameters namely fluid pressure, friction coefficient at blank/punch interface, gap between die rim block a...

Incremental sheet forming (ISF) technology is a suitable and flexible solution to create complex 3D geometries of the sheet. A gradually formed into desired shape with tool usually attached CNC machine or robot. This process valid metal as well polymer sheets. However, inaccuracy geometry occurring errors in previously discussed industries prove novelty technology.
 In this research novel ...

The forming defects of parts mainly include fracture, springback, thermal expansion, and rough surface during electric hot incremental forming, in which the springback expansion directly affects dimensional accuracy parts. In this paper, combined optimization process parameters unsupported distances was proposed to control sheet process. predictive model major errors established through respons...
