Precision engineering is a subdiscipline of electrical engineering , software engineering , electronics engineering , mechanical engineering , and optical engineering concerned with designing machines, fixtures, and other structures that have exceptionally low tolerances , are repeatable, and are stable over time. These approaches have applications in machine tools , MEMS , NEMS , optoelectronics design, and many other fields.
1-781: Clerget-Blin (full name being Société Clerget-Blin et Cie ) was a French precision engineering company formed in 1913 by the engineer and inventor Pierre Clerget and industrialist Eugène Blin . In 1939, the company was absorbed into the Groupe d'étude des moteurs à huile lourde (GEHL; "Diesel Engine Study Group"), which was further merged into SNECMA in 1947. The Clerget-Blin company mainly produced aircraft engines. Their successful rotary engine designs were also built in Britain by companies such as Gwynnes Limited , Ruston Proctor , and Gordon Watney , to increase production during World War I .
