Emeritus Professor David Allen started his career as a chemist (BSc, 1968)
and moved into photochemistry research (PhD, 1972) while studying at Cardiff
University. Following post-doctoral research at Warwick University and imaging
technology development in industry, David joined Cranfield University in 1976.
He was appointed a Technical Liaison Member to the Photo Chemical Machining
Institute (PCMI) in 1981 and is currently on the Board of Directors of PCMI
responsible for education. David became Professor of Microengineering at
Cranfield University in 1998 and was elected as a Fellow of The International
Academy for Production Engineering (CIRP) in 2006.
David has published:
• Two PCM books:
“The Principles and Practice of Photochemical Machining and Photoetching” (1986) and “Photochemical
Machining and Photoelectroforming” (2015, reprinted 2016, 2017 and 2019)
• Five book chapters on non-conventional machining and contributed the chapter on ‘Etching’ to the on-
line CIRP Encyclopedia of Production Engineering
• Seven confidential industrial PCM consortium reports
• 213 journal and conference papers and was awarded the higher doctoral degree of DSc from
Cranfield University in 2013 for his thesis entitled “Contributions to Photochemical Machining and
Photoelectroforming”.
David retired from academia in 2011 and he now carries out consultancy and staff training in PCM
companies across the world. He has worked with 28 different companies over the past 13 years.
