Multi-sensor metrology for microparts in innovative industrial products

Short Name: Microparts, Project Number: IND59
Gears background
Measurements for microparts: Measuring small, complex, features in three dimensions

Parts which are a millimeter or less in size are becoming increasingly important in industry and daily life, for example when it comes to scaling down technical equipment, reducing power consumption or saving raw materials. Quality assurance for these parts is a major challenge, as measurement is required below the micron scale in a range of complex geometries and surface characteristics. At present, tactile coordinate measuring machines (CMMs) are limited by the probe size, speed of measurement and wear. Alternatives are optical sensors or Computed Tomography (CT), but although these are fast they are not as accurate as tactile CMM and the measurements are not traceable. This project developed smaller tactile probes and aimed to achieve traceability for optical sensors and CT. It also looked at improving the accuracy of optical sensors and CT, and combining the data from the different techniques to implement multi-sensor measurements. Working closely with three manufacturers, the project developed and categorised workpiece like reference standards, which could be used to achieve traceability of industrial measurement tasks.
