FoldingRuler opti control system for folding ruler measurements

FoldingRuler opti control works in the Metrie company to verify declared lengths of folding rulers.

The inspection device is design as a single-purpose machine providing, after manual insertion of a folding ruler, for its complete analysis and inspection of all dimensions given to the manufacturer of length measuring instruments by law. This project required communication with the Czech Metrology Institute so that proper ways of control and accuracy were chosen. The final product is able to automatically check folding rulers with the accuracy higher than 0.025mm and speed higher than 30s.
