Foundry modernisation with GOM optical 3D metrology solutions

Shape and dimensional analysis of castings with tactile coordinate measuring systems has its limitations. Implementing optical 3D metrology into your operation enables inspection processes to be accelerated.

Measuring systems from GOM are used in sand, pressure die and investment casting processes to guarantee consistent quality assurance, from simulation verification, via accelerating tool try-out and first article inspection, up to production control and CNC machining.

GOM systems allow for inspection planning based on design data. In pattern and mould making, the targeted correction of tools and models and the inspection of fitting of mould halves, cores and sliders are possible. During try-out, cast parts are checked for shape and dimension: part geometry, material thickness, shrinkage and warpage. All measuring and inspection processes are automated for production quality control.

GOM recently launched its ATOS Capsule optical precision measuring machine.
The ATOS Capsule uses a fringe projection system and excels its high precision for fine details. The ATOS Capsule sensor return full-field distributed 3D coordinates for each individual measurement. Up to 12 million independent measuring points are captured within 1 to 2 seconds. The measuring data is characterized by highly detailed reproduction, thus also enabling very small component features to be measured.

The ATOS Capsule can be used fully automated when integrated in the ATOS Scan Box modular measuring machine. Combined with the photogrammetric add-on sensor ATOS Plus, bigger components or several parts can be measured simultaneously with higher accuracy.

Triple scan technology
With duel cameras, the projection unit operates according to the triple scan principle. During the measurement, precise fringe patterns are projected onto the surface of the object and are recorded by two cameras, based on the stereo camera principle. This automatic principle offers advantages in measuring reflective surfaces or objects with complex indentations.

New aspects in industrial 3D metrology, inspection and testing to be presented – 15 March 2018
GOM, a global industrial company that develops, produces and distributes software, machines and systems for industrial and automated 3D coordinate measuring technology and 3D testing and local partner RGC Engineering will hold a one day conference on 15 March 2018.

The conference is an industrial meeting platform for design engineers, tool makers, production and quality assurance executives, metrologists, foundrymen and experts from well-known companies and research institutions to learn about the latest developments in optical measuring technology.
