Optical Multi–Gauge System for Quality Assurance

Wenzel ScanTec presents a newly developed optical multipoint-measuring-system, the Core-DG. The measuring system offers a valuable technical and commercial alternative to traditional tactile multi-point-measuring-systems. Their significant disadvantage, however, is their lack of flexibility and dedication of the device to a single part design. In the event of a part design change an expensive fixture redesign must take place. An increasing trend is the introduction of new designs in shorter times, which consequently has an increasing impact on time and cost.

This is where the new solution of Wenzel ScanTec provides a valuable alternative. Using an optical sensor measuring points on the part are defined and recorded. Several defined points are recorded with an optical sensor. A highly dynamic 5-axis system provides optimum accessibility to the part. The speed of measurement is fast and similar to that obtained from traditional tactile systems. Unlike many other optical technologies shiny surfaces do not need to be coated in advance of measurement which would be a huge draw-back of the offered solution.

The real strength of the optical multipoint-measuring-system takes effect when switching over to a new component design. In contrast to tactile multipoint-measuring-systems no special sensor holding fixture must be defined and manufactured. Reconfiguration is easily realized by simple reprogramming using the associated software modules. Converting times are reduced to a minimum as are associated costs and training efforts. The total system can be implemented for operation on the production floor using a single-button operation. The robustness of the solution allows its use even in the most hostile production environment.

The system is manufactured by the Wenzel Group providing a seamless solution integrating precision mechanics, software and motion controller. Typically, they are used in the automotive, aerospace and medical industries for, production based, quality assurance of manufactured parts.
