Fully automatic inline inspection of freeform geometries

A flexible measuring cell to automatically check freeform geometries directly in production has led to an increase in quality for Boysen, a supplier in innovative emission systems. Both, the quantity of rejects and component replacement have been significantly reduced.

Alicona Imaging, the 3D specialist and supplier in optical measurement and inspection has developed a customised system for Boysen. The system is used for 100% inspection and control of exhaust manifolds focusing on particular features such as evenness of the flange face.

All measurements are made according CAD model and achieve an accuracy of better 0.02mm in seconds. Innovative algorithms allow, for the first time, 3 dimensional measurement instead of common point per point techniques.

Based on the interaction of optical measurement components and industrial robotics the measuring cell provides outstanding results as flexible as the total system.

A simple re-selection of the appropriate software allows adjustment to different types of components in addition to the relocation of measurement points. It is also not necessary to refit the system which makes it to a unique tool in quality assurance.
