In modern CNC systems, the design of a mechanical part and its manufacturing program is highly automated. In other installations, a number of different machines are used with an external controller and human or robotic operators that move the component from machine to machine. The first NC machines were built in the 1940s and 1950s, based on existing tools that were modified with motors that moved the controls to follow points fed into the system on punched tape. As the controller hardware evolved, the mills themselves also evolved. One change has been to enclose the entire mechanism in a large box as a safety measure, often with additional safety interlocks to ensure the operator is far enough from the working piece for safe operation. CNC-like systems are now used for any process that can be described as a series of movements and operations.
