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 ...

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, $$\phi_{ \hbox{max} }$$

Simulation Study for Robot-based Single Point Incremental Forming

International Conference on Industrial Engineering, Applications and Manufacturing, 2023
The present study investigates the toolpath definition for the numerical simulation of the Single Point Incremental Forming (SPIF). Since the toolpath definition greatly influences the geometrical accuracy of the formed part, substantial research has ...

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 ...

Desktop Single Point Incremental Forming System

ASME 2010 International Manufacturing Science and Engineering Conference, Volume 1, 2010
This paper proposes a novel thin shell curved surface forming method by dieless single point forming technology embodying the thought of the parallel running for both design and manufacture. And a sheet metal superplastic forming prototype system with a heterogeneous master-slave manipulator by force-reflecting control has been developed.

Theory of single point incremental forming

CIRP Annals, 2008
This paper presents a closed-form theoretical analysis modelling the fundamentals of single point incremental forming and explaining the experimental and numerical results available in the literature for the past couple of years. The model is based on membrane analysis with bi-directional in-plane contact friction and is focused on the extreme modes of

Single Point “Dieless” Incremental Forming

2015
The dieless NC forming process was developed in Japan as a flexible, alternative manufacturing method to effectively prototype sheet metal stampings and produce production panels with complex shapes in small quantities. It is extremely cost effective, as conventional tooling is not required.

Effect of Isostatic Pressing Support on Forming Force in Single Point Incremental Forming

Integrated Ferroelectrics, 2023
Single point incremental forming has no support on the back of the sheet, which leads to the defects such as sheet instability and poor forming accuracy.

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 ...
