METALLURGY

Secteur d'activité metalurgie

Extremes conditions that make Vision control necessary.

Metallurgical sector implies extremes fabrication conditions: foundry or furnace temperatures, projections, access or visibility difficulty, dust, mesure precision…

Machine Vision appears to be necessary to realise an efficient production control. Also, it assures the security of technicians.

Thanks to a close partnership with the customer, we can face technical challenges imposed by the sector and conserve the “savoir-faire” on our territory.

Profilomètre 3D

Outline profil 3D measurement.

Measurement bench allowing to extract height profile of products relying on marble.

Precision and measuring range depend on products to control.

Dimension and aspect control on rings

Difficulty: consider the blur.

CHECKS MADE:

  • Dimensional (interne circularity, strip width),

  • Aspect (impact presence, porosity, micro-scratches)

Traitement contrôle rivet

Rivets control

  • 6 cameras system on 2 stations,
  • Custom lighting,
  • Rate: 250 p /min.

CHECKS MADE:

  • Dimensional control (diameter, thickness, length, angle, burr),

  • Thread presence,

  • Joint control (lift-off, overflow, continuity).
