Review of recent stretch forming development
Journal Title: Proceedings in Manufacturing Systems - Year 2018, Vol 13, Issue 3
Abstract
The forming process, reviewed in the present paper, is a conventional method used in deforming metal sheet, using a clamping method and a die. Through the paper numerous types of processes were shown. The main consideration was the mechanists behind each process and how it improves key factor like producibility, repeatability, sustainability and conformability. Described in the introduction is the different type of sheet metal forming processes, the deformation mechanism, deform materials, industries where it is successfully implemented. The main types of processes described are classic die stretch forming, multi-point die stretch forming (MPSF), single point incremental forming (SPIF) combined with stretch forming and numerical simulation of the stretch forming process, with respect to classic die, multi-point die and flexible multi-grippers. More or less the aerospace industry has a high use of stretch forming parts. Nevertheless, industries like architectural constructions, automotive and naval benefit from the major developments of this process. MPSF and the hybrid SPFI and stretch forming processes solved the problem of multiple curvature sheet deforming, grooves and pockets. As a conclusion, to this review, it can be stated that conventional stretch forming has undergone a remarkable evolution in term of process adaptability and flexibility, being able to perform operations of high complexity.
