Mapping
Triangulation Laser sensing provides a non-contact method of mapping both metallic and coated components. This is used for both feature location and component shape mapping. Predominantly used for circular combustor type components, the component is mapped and positionally compensated for eccentricity and roundness to facilitate correct machining of the cooling holes by EDM or Laser. These types of components are often fabricated and therefore much less accurate than machined parts, so the use of mapping to compensate for deformities on the component surface, gives rise to a much more repeatable hole diameter and visually acceptable cooling hole pattern or feature.
