Résumé
Research on incremental sheet forming started decades ago but has not yet found its momentum. To become a mainstream technology, two key enablers are required: geometrical accuracy and usability. The added formability and accuracy provided by double sided incremental forming (DSIF) is a promising improvement but comes with additional challenges, such as toolpath definition. This paper is presenting a novel strategy to determine tool positioning without using a squeezing factor, sine law, or other conventional techniques. First, the master toolpath is calculated with CAM software. Then, a coupling between the master and the slave is numerically imposed to precisely simulate their positions while ensuring continuous contact and a variable support force. Upstream deformations are thus minimized throughout the complete forming of the part. This strategy was applied to a step cone geometry, and the numerical results show only slight deviations from computer-aided design (CAD).
