The Early Days of CNC Function

Although the suggestion had been around for some time, the first Numerical Control idea had not been developed up until 1949. John T. Parsons, an early computer pioneer, established it as part of an Air Force study task accomplished at the Massachusetts Institute of Technology, or MIT. An experimental milling machine was developed at the institute’s Servomechanisms Laboratory, with the objective of utilizing motorized axes to generate helicopter blades, as well as stiffer skins for the airplane.

Parsons Company in Traverse City, Michigan, got to work with the first system also before the MIT cooperation. Parsons was able to use an IBM 602A multiplier to determine airfoil coordinates. The data points were fed into a Swiss jig borer by feeding punched cards into the system. Preprogrammed details might be used to generate components for helicopters; this was the precursor to CNC maker shows.

The concept was more developed in 1952 by Richard Kegg, in partnership with MIT, who introduced the Cincinnati Hydro-Tel, a 28-inch vertical-spindle contour milling machine. It’s commercial introduction included a license for an “Electric Motor Controlled Apparatus with Placing Maker Tool.” The preliminary prototype, although it was run using eight-column paper tape, a tape reader, as well as a vacuum-tube digital control system, became an emphasis for future advancements.

Early CNC makers in the 1940s-1950s utilized punched tape, which was then frequently utilized in telecoms and information storage space. This technology was replaced by analog computing technologies. From the 1960s through the 1970s, electronic technologies developed, making the manufacturing process automated, as well as extra reliable.

Parsons was granted for his early work. In 1968, he got the first Joseph Marie Jacquard Memorial Award from the Numerical Control Society. The Culture of Production Engineers awarded him an honorary plaque in 1975, which named Parsons “The Father of the Second Industrial Revolution.”
