Improving die rework capability opportunities for using 3D non-contact measurement technology to reduce die tryout iterations to resolve dimensional issues.
This report summarizes automotive body die tryout performance, based on a survey of and interviews with die manufacturing experts from automotive body manufacturers and die suppliers, The report explores opportunities for more effectively integrating new 3D noncontact optical measurement...
Integrating 3D non-contact measurement in the die tryout business process
Based on two surveys of manufacturers, this report summarizes several automotive body die tryout buyoff criteria, rework processes, and 3D non-contact measurement strategies. Relative to historical die tryout performance levels, a significant reduction in the number of iterations is clearly...
Datum transformation analysis for production part approval using 3D non-contact measurement
This paper presents a comprehensive dimensional validation methodology, known as datum transformation analysis (DTA). The DTA approach utilizes 3D non-contact (3DNC) measurement to obtain a full part dimensional representation at all critical matching interfaces of a part assembly to the vehicle....
Quantifying alignment effects in 3D coordinate measurement
The use of fixtureless, non-contact coordinate measurement has become increasingly prevalent in manufacturing problem solving. Manufacturers now routinely use measurement systems such as white light area scanners, photogrammetry, laser trackers, and portable laser scanners to conduct studies that...
