jan 1, 1960 - CMM
Description:
The Coordinate Measuring Machine first appears in the early 60s and is made of 3D tracing devices with a simple digital readout (DRO) displaying the XYZ position. The initial CMM was developed by the Ferranti Company in Scotland during the 50s. This unit, however, had only two axis. The very first three-axis prototypes arrive during the 1960s and are invented by the Italian company DEA (now part of the Hexagon Metrology Group).
Soon afterwards, automated CMMs appear in the 60s to perform complex inspections of Concorde supersonic jet engines. This invention leads to the creation of the Renishaw Company in 1973, now the main supplier of CMM measuring heads.
