Text h. 1940s-1970s
By 1940, automation via cams, such as in screw machines and automatic chuckers, had already been very well developed for decades. By the close of Word War II, many additional ideas
involving servomechanisms were in the air. These ideas, which soon were combined with the emerging technology of digital computers, transformed machine tool control very deeply. The details (which are beyond the scope of this article) have evolved immensely with every passing decade since World War II.
During the 1950s, numerical control (NC) made its appearance.
During the 1960s and 1970s, NC evolved into CNC, data storage and input media evolved, computer processing power and memory capacity steadily increased, and NC and CNC machine tools gradually disseminated from the level of huge corporations to the level of medium-sized corporations.
1980S-present
Computers and CNC machine tools continue to develop rapidly. The PC revolution has a great impact on this development. By the late 1980s even mom-and-pop machine shops can have desktop computers and CNC machine tools. CAD/CAM disseminates throughout the economy.
