The Institution of Engineering Technology (IET) is presenting an event about how 3D optical scanners are rapidly growing in popularity for manufacturing production lines. The presenter is Martin Dury of NPL”s Optical Radiation Measurement (ORM) group.
About this event
Fringe projectors, articulating arm coordinate measuring machines (CMMs) incorporating laser scanners and other types of portable 3D optical scanners are quickly being taken up onto manufacturing production lines and replacing Cartesian-based tactile probing CMMs because of their advanced metrology benefits, such as massively increased measurement speeds, equipment portability and relative ease when measuring freeform surfaces. Having been developed in the 1950s, Cartesian CMMs are well understood and trusted, while methods of verifying their performance are well established. In contrast, optical scanners, whose development has accelerated with increasing access to low cost, powerful computers and cheaper optics, are relatively new and still being developed.
This presentation explains the evolution of dimensional measurement in industry from CMMs to optical scanners and describes the issues in transferring the latest technology from the laboratory to the factory floor and beyond.
About the speaker
Martin Dury joined NPL’s Optical Radiation Measurement (ORM) group in 2006, having completed his PhD in the development of a novel mid-infrared radiance standard at the University of Reading. While in the ORM group, he worked in photometry and radiometry, progressing to responsibility for the cryogenic radiometer, the UK’s primary standard for the measurement of optical radiant power. With a general interest in applied optics, Martin changed areas in 2013 to join NPL’s dimensional group where he became responsible for the National Freeform Centre’s 3D optical scanner characterisation facility, a purpose-built laboratory to support the UK’s growing industry in non-contact dimensional metrology. He is now applying the knowledge that he acquired while investigating the limitations of dimensional 3D scanning instruments to lead efforts in the development of a traceable 3D optical scanner.
