  12. CNC or Computer Numerical Control is a term • derived from NC or Numerical Control. • NC refers to Control of a process or automatic • operation of a machine by using symbolic codes • consisting of characters and numbers. • NC was introduced in late 40’s to control machine • tools such as Drilling and Milling machines. One of • the first applications of NC machine tool was in • production of helicopter rotor blades and ship • propellers. Evolution of Machine Tools

  13. John T Parsons introduced NC machine tools for which he was awarded a patent titled motor Controlled apparatus for positioning machine tool control (patent No: 2820187) Evolution of Machine Tools • Computer Numerical Control (CNC) is a term • derived from NC or Numerical Control in 70s • when micro-processor and computer based NC • controlled machines were built.
