![]() 3-Axis, 3D SystemsĪ classic CMM has an X, Y, and Z axis and operates in a 3D system. This invention resulted in a revolution of 3D measurement, opening the world up to accurate and automatic measurements of separate components and entire assemblies. The co-founder of Renishaw, Sir David McMurtry, invented the Touch Trigger Probe in 1970, which enabled the Olympus engines used in Concorde aircrafts to pass specific requirements. After this their use by businesses of all sizes quickly gathered pace. Several big companies from the most developed countries of that time, including the USA, Japan, Germany, and France joined in the production of commercial CMMs during the 1960s. They were manufactured by Ferranti, a British company that also developed the first commercial computer for a general audience in 1951. The history of CMMs started in 1959 when they first appeared at the International Machine Tool Exhibition in Paris. As ubiquitous as CMMs now are in manufacturing, it is hard to imagine a world when quality control was dependent on hand measurements. These CMMs can be Manual, where an operator guides the machine, CNC machines that are driven automatically by a special program. The modern CMM industry produces over 6,000 new CMMs every year, as well as retrofitting and upgrading tens of thousands more. Coordinate Measurement Machines have an interesting history going back almost 60 years.
