CNC History


1947 - John Parsons began experimenting with the idea of generating thru-axis curve data and using that data to control machine tool motions. 


1949 - A contract was granted to the Parsons Corporation to search for a speedy production method. 


1952 - MIT successfully demonstrates a model of the NC machine of today. The machine successfully made parts with simultaneous thru-axis cutting tool movements. MIT coined the term "numerical control". 


1955 - Commercial models of NC machines displayed for customer acceptance. 


1957 - NC accepted by industry; several are installed and in use.
