Single Point Incremental Metal Forming

Brooklyn Says, "Move to Detroit": Project Proceedings, 2017
Single Point Incremental Metal Forming(SPIMF) is a process that allows architectural panels to be incrementally formed from sheet metal into doubly-curved complex shapes using a robotic arm and a stylus-like end effector. SPIMF leverages industrial robots’ precision and strength by gradually pushing the end effect or into vertically supported sheet ...

Single point and asymmetric incremental forming

Advances in Manufacturing, 2015
This paper presents an update on single point incremental forming (SPIF) of sheet metal since 2005. It includes a description of the process with new information on the maximum forming angle, $$\phi_{ \hbox{max} }$$

Single point incremental forming of PVC

Journal of Materials Processing Technology, 2009
Abstract Polymers represent an important percentage of the raw materials currently utilized in manufacturing applications but their conventional processing techniques are mainly suitable for mass production. Growing requirements of low volume, high quality, customized products are triggering the need for developing innovative flexible polymer ...

Failure in single point incremental forming

The International Journal of Advanced Manufacturing Technology, 2015
This paper revisits the formability limits of single point incremental forming (SPIF) in the light of fundamental concepts of plasticity and ductile fracture mechanics. The paper has a twofold objective of investigating the limiting strain pairs at fracture in parts showing and not showing signs of necking before cracking and of demonstrating that ...

Theory of single point incremental forming of tubes

Journal of Materials Processing Technology, 2021
Abstract Knowledge of the deformation mechanics in single point incremental forming of tubes is of great importance to understand the physics behind failure and the workability limits in thin-walled tube expansion. Which are the states of stress and strain in the small localized plastic deformation region between the tube and the single point forming

Twist in Single Point Incremental Forming

ASME 2012 International Manufacturing Science and Engineering Conference, 2012
Twist in incremental forming is observed in all configurations including single point incremental forming. In addition to tangential force, other parameters like stiffness seems to play a significant role in the twist phenomenon. Present work makes an attempt to experimentally study the twist in SPIF of conical components and compare the same with ...

Formability of polycarbonate sheets in single-point incremental forming

The International Journal of Advanced Manufacturing Technology, 2019
The paper investigates the influence of tool diameter, sheet thickness, and geometry of the workpiece during single-point incremental forming (SPIF) of polycarbonate sheets. An experimental campaign was conducted and involved varying and fixed slope angle tests. The process was performed at room temperature.

Asymmetric Single Point Incremental Forming of Sheet Metal

CIRP Annals, 2005
The use of computers in manufacturing has enabled the development of several new sheet metal forming processes, which are based upon older technologies. This paper describes modifications that have been made to traditional forming methods such as conventional spinning and shear forming, forming processes in which deformation is localized.

Sheet Thinning Prediction in Single Point Incremental Forming

Advanced Materials Research, 2005
Incremental forming processes are characterized by a well known and particular feature: any deformation across the sheet plane determines sheet thinning, since the blank is fully clamped by means of a proper equipment. As a consequence, the availability of effective and reliable CAE tools capable to supply an accurate prediction of sheet thinning as a ...

Progress on single-point incremental forming of polymers

The International Journal of Advanced Manufacturing Technology, 2021
Single-point incremental forming (SPIF) of polymers was started back in the first decade of twenty-first century; since then, substantial studies have been performed on this topic. The present article reviews these studies and compiles the developments in a comprehensive manner.
