Dimensional measurements

Dimensional measurement and inspection of components

Complex artefacts for specialised measurements

We operate a measurement and inspection service for customers who require high accuracy measurement of artefacts, components or reference masters. This service covers a wide range of standard or highly complex artefacts, such as turbine blades, ceramic cores, aerofoils, injection mouldings, medical prostheses, precision components, jigs and fixtures.

We have a wide range of measurement facilities for accurately determining the dimensions of components and features whose scales range from the very tiny to the very large. Our capabilities range from traceable atomic force microscopes with sub-nanometre accuracy to laser tracker systems capable of measuring over many metres. Measurements may be made by tactile methods, e.g. touch probe coordinate measuring machines (CMMs) and articulated arms, or by non-contact methods, e.g. laser scanners, fringe projection, photogrammetry, vision CMMs and laser trackers. Experienced metrologists, with extensive expertise in first principles measurement, underpin our measurement capability.

Our main capabilities include:

  • CMMs, articulated arms and laser scanners
  • Non-contact dimensional measurements
  • Fringe projection and photogrammetry
  • Laser trackers
  • Surface topography

Our experts will help select the appropriate measurement method, taking into account factors such as the level of accuracy required, the time to make the make the measurement and the scale of the component and features of interest. Tactile techniques typically have the highest accuracy. Non-contact methods can be rapid and may be used for measurements of delicate artefacts or soft components, in situations where touch probe methods are less suitable, such as hazardous environments. Many of the methods are portable allowing measurements to be made in-situ.

Data taken from the different techniques can be stored as 3D point clouds and data sets can be merged. Captured data may be used to measure/inspect, compare to design or even reverse engineer the object.
