| Definition / notes: | Numerical control or numerically controlled (NC) machine tools are machines that are automatically operated by commands encoded on a digital medium. NC machines were first developed soon after World War II and made it possible for large quantities of the desired components to be very precisely and efficiently produced (machined) in a reliable repetitive manner. These early machines were often fed instructions which were punched onto paper tape or Hollerith cards, although Mylar (or polyester) tapes became popular because of their high durability and quality. In the 1960s, NC machines largely gave way to CNC, or computer numerical control, machines. (GE had its NC 550 workhorse for many years until they came out with their first CNC (model 1050) in August 1974.) |
