- Abstract:
- Today many different systems are working in accordance with the idea of coordinate measuring technique. There is possibility of using the same measuring software with optical or contact coordinate systems as well as with a 3d scanners (structural or laser light). This gives the opportunity to use different measuring systems for the same tasks. Consequently, it is possible to build faster and more efficient techniques for controlling the production. For example: a fast check of car body production with 3d scanner systems and one per shift accurate measurement of the same element with reference Coordinate Measuring Machines. The main purpose of measurements in industry is assessment of the conformity or nonconformity of the production with the specification. The specification can be written in classical paper documentation or saved in CAD-file. Never-mind how specification is written or saved, the uncertainty of the measurement should be taken into consideration, according to the ISO 14253-1 guideline. In the case of a supplier - to his benefit, by extending the area of conformity and in the case of production control - by reducing the area of conformity.
