MEASURING MACHINES Created to simplify and improve the work of the inspection staff with the traditional metrology systems. With these machines you can detect the size of 3-d machined parts and compare them with data design theorists. There are manual and motorized machines. The first CMM model was designed between the fifties and sixties years, was created to meet the growing need for greater speed and accuracy in the control of pieces produced by the new CN machines. In 1973, the DEA company of Turin in Italy, marketed the first automated CMM in the world.
