Characterisation of Areal Surface Texture

Autorenportrait

<p>Richard Leach is a Professor in Metrology at the University of Nottingham; prior to this, he spent 25 years at the National Physical Laboratory. Richard is currently an ERC Advanced Grant awardee and is recognised worldwide by his research into surface topography measurement, particularly in the area of traceability for areal surface texture, including optical instruments. Along with research into surface-function relationships and many other areas of general dimensional metrology, his research has made a major contribution to the use of surface topography engineering and control in a wide range of industrial applications including advanced manufacturing, tribology, aerodynamics and even archaeology. One of his major contributions was the establishment of traceability for areal instrumentation, including primary instrumentation, transfer artefacts and good practice guidance. This work has led to ISO standards based on his research outputs whilst at the National Physical Laboratory. He has also contributed to a theoretical framework that can be used to predict the interaction of light with a surface and hence, to design, calibrate and correct 3D optical instruments. Complementing these advances in science, he has been prominent in precision engineering, with major industry collaborations involving advanced product manufacture and the recent production of an undergraduate textbook. In 2018, Richard formed a spin-out company, Taraz Metrology, to commercially exploit information-rich metrology, mainly in the additive manufacturing sector. In 2019, Richard was awarded the Finkelstein metal by the Institute of Measurement and Control, for notable contributions to measurement internationally.</p>
