Theory of single point incremental forming

CIRP Annals - Manufacturing Technology, 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

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

Prediction of forming forces in single point incremental forming

Journal of Manufacturing Processes, 2017
Incremental sheet forming (ISF) is a cost effective die-less forming process for low volume production. Achieving good accuracy using this process is a challenging task. Bending between clamped boundary and component opening, tool deflection, sheet spring-back and rigid body displacements are the major reasons for geometric inaccuracy in components ...

Single point incremental forming

International Journal of Materials and Product Technology, 2008
Traditional sheet metal forming requires expensive dedicated dies, both positive and negative dies, where each die mimics one side of the desired part. Modern manufacturing industry strives to be flexible and to respond to customer needs. This trend toward flexibility requires new sheet metal forming methods.

Incremental Single Point Forming

Manufacturing Engineering, 2000
Abstract The process of single point incremental micro-plastic forming is presented. This process is used to form sheet metal into complicated shapes without the use of either a male or female die. The process uses a single point tool which plastically deforms sheet metal to give a local micro-deformation.
