Photogrammetric Measurement Techniques for Quality Control in Sheet Metal Forming
نویسندگان
چکیده
Within the Brite/EuRam project “DIGIMAN” a new optical measuring system for the assessment of sheet metal components in terms of shape accuracy and strain distribution has been developed. Based on the photogrammetrically measured geometric parameters of the object the system detects deviations from the desired geometry caused by springback and allows the strain analysis within critical stamping part areas. Such a system was installed at the Institute for Metal Forming and Metal Forming Machine Tools (IFUM) of the University of Hanover. Further systems will be implemented at different car manufactures and producers of sheet metal stamping parts. Typical applications of photogrammetric measurement techniques in sheet metal forming are described in the following paper.

In this paper instability of planar anisotropic sheet metal during a few forming processes is investigated for the first time. For this reason components of the constitutive tangent tensor for planar anisotropic sheets are developed. By using the above tensor location of necking is predicted. Direction of the shear band is also predicted using the acoustic tensor. A finite element program is pr...
