We have several co-ordinate measuring machines (CMMs) suited for different sizes of components, from sub-millimetre to around one metre, which can be programmed to measure a wide range of features ranging from simple dimensions such as lengths, diameters, radii, through form and geometry parameters including flatness, straightness, parallelism, cylindricity, to complex geometry elements such as angular intersections and plane angles. Measurements of artefacts against CAD models or drawings can be undertaken and article inspection reports produced. One CMM is fitted with a laser scanning head, which can be used to rapidly scan an object.
Large objects can be measured using seven axis articulated arms, fitted with laser scanners and touch probes. These can rapidly measure an object whilst giving the operator great flexibility to access complex shapes.
Extremely small components (size in the order of tens of millimetres) and those that have small features can be measured on a micro-CMM with sub micrometre accuracy or a variety of unique NPL built instruments, including a metrological AFM.
NPL can develop and validate specific CMM programmes for parts with complex features and tight tolerances.
Independent CMM programme validation
UKAS accredited measurements available
NPL also provides a one-stop service for the characterisation of the form and texture of surfaces through an extensive range of facilities.
