Large and complex ring forgings are key structural parts of the aerospace field, and their
quality is closely related to the reliability of aerospace vehicles. However, high-quality …

Elastic recovery of the material, called springback, is one of the problems in sheet metal
forming of drawpieces, especially with a complex shape. The springback can be influenced …

The current paper aims to review tooling life span, failure modes and models in cold
microforming processes. As there is nearly no information available on tool-life for …

This paper studies the effects of geometrical errors on the repeatability of positioning of
linear axes, based on theoretical modeling and an experimental study. Firstly, this paper …

The elastic deformation of rolling mill elements during the rolling process is important. By
knowing the displacement of rolls, the optimum gap between the work rolls can be …

The forming tools are commonly assumed as rigid in the finite element simulation of sheet
metal forming processes. This assumption allows to simplify the numerical model and …

High-strength steels have been increasingly used for vehicle body structures to improve fuel
efficiency and vehicle safety. In order to maintain the stiffness and forming conditions under …

Advanced high-strength steels (AHSSs) exhibit large, and sometimes anisotropic,
springback recovery after forming. Accurate description of the anisotropic elasto-plastic …

Several vehicle platforms involving the hot stamping of manufactured parts are launched
every year. Mass production represents a key step in the manufacturing process of an actual …

Any manufacturing equipment designed from scratch requires a detailed follow-up of the
performance for the first units placed in service during the production ramp-up, so that …
