Patent Number Date Title Name City Description 470,245: Mar. 08, 1892: Tail-stock for milling-machines: Thomas L. Smith
Parsons hoped to create an instrument that would repeatedly cut out the same template, showing that it could repeat the same actions over and over again. In 1952, Richard Kegg created the first milling machine, also in collaboration with MIT.
From an apprentice in a machine tool shop in Detroit to industrialist and inventor, John T. Parsons took on the role of molding the machine tool industry from an imprecise craft to the exact science we know today as CNC and in the process changed the face of the world in a truly remarkable way. Today John Parsons is 86 years old and still lives ...
An experimental milling machine was built at the institute's Servomechanisms Laboratory, with the goal of using motorized axes to produce helicopter blades and stiffer skins for aircraft. Parsons Corporation in Traverse City, Michigan, got to work on the first system even before the MIT collaboration.
John Parsons, on why it took so long between licensing the NC patent and the widespread use of NC: ... Virtually unattended, these machines were drilling, boring, milling, and passing unrelated ...
The world's first successfully developed CNC machine tool was a three-coordinate CNC milling machine, which was completed in 1952 by the American Parsons company (Parsons) and the Massachusetts Institute of Technology (MIT).
The History of CNC Machines. John T. Parsons (1913-2007) of Parsons Corporation in Traverse City, MI is considered the pioneer of the numerical control, the precursor to the modern CNC machine. For his work, John Parsons has been called the father of …

Parsons' work lead to numerous Air Force research projects at the Massachusetts Institute of Technology (MIT) starting in 1949. Following extensive research and development, an experimental milling machine was constructed at …
•What is a CNC Machine? ... C. Parsons of the Parsons Corporation, Traverse City, Michigan, a manufacturer ... today's NC machine, a modified Cincinnati Hydrotel Milling Machine, was successfully demonstrated. The term numerical control was originated at MIT.

His journey to create this machine took him to the Massachusetts Institute of Technology (MIT) and the Air Force. They built the Air Force Numeric Control and Milling Machine in 1952, and it was a huge success. The machine was programmed by punch tape, though, and not Parsons' original punch card design.
In 1947, Parsons developed a method allowing milling machine operators to produce airfoil templates to check blades using a chart of table and cutter settings prepared on IBM punchcard machines. Within two years of that initial innovation, Parsons was working on a punchcard system that totally controlled a milling machine — the first ...
It was the year 1952,due to the need for precise machining of parts in the aviation industry,when John T. Parsons, in collaboration with IMB (International Business Machines Corporation) and MIT (Massachusetts Institute of Technology), developed the first CNC milling machine.
The milling machines used are thus automated and controlled by a computer to machine a block of material to create a part. ... John T. Parsons then motorised the axes of the machines for making these blades. Working with IBM, he studied the possibilities of controlling these machines by computer. This was the starting point of the CNC machining ...
Patent filed by John T. Parsons. The CNC was invented in the late 1940s by John T. Parsons.He originally called it a Card-a-matic Milling Machine because the computer that controlled it read punch cards.. Apparently not happy with that name, Parsons held a contest to choose a new one.

Numerically controlled machines are safer to operate, and the complex geometry comes at a reasonable price. James T. Parsons proposed the concept of the numerical control operations during the year of 1948. In 1950, the MIT servo mechanism lab developed the Numerical Control (NC) milling project.
Parsons NC Milling Machine. After World War II, Parsons was busy in developing rotor blades for aviation industry. For its complexity involved in shape, it was an uphill task to achieve precision, which was an utmost requirement. With his connections with an IBM computer, he realized that it is quite possible to produce accurate contour guides ...
John T. Parsons1913- American engineer who developed automated controls for machine tools, helping to turn many milling and shaping processes into precision, computer-guided tasks. Prior to Parsons's inventions, most of the processes on assembly lines still took place by hand at metal lathes and milling machines, resulting in a lack of precision and consistency.
