Abstract
The paper describes some advances in the use of grid analysis and forming limit diagram techniques. It is shown that a limited amount of process or tooling related information can be derived from the measurements of the grid distortion at localized areas. It is illustrated that a full three dimensional grid analysis of the part is required for a comprehensive understanding of the interrelation between the state of deformation at different regions and the possible improvement in process.
