Parsons Engineering. With over 100 years of combined experience, Parsons Engineering Pty Ltd is a Sydney-based, Australian owned precision CNC engineering company specialising in highly complex machining. Few other engineering workshops can match Parsons expertise in using such exotic materials as SAF2507 stainless steels, titanium, copper and ...

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.

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 …

Parsons built a milling machine which was fed data to automatically activate servo-mechanisms to perform automatic contour cutting. First developed for making jet plane wings, the method is now widely used in the manufacture and assembly of many goods, from automobiles to computer chips. (1993) Bradford Parkinson The National Inventors Hall of Fame

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.

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 ...

Parsons began motorizing the axes that made the blades. Parsons would eventually team up with IBM to start controlling the machines using a computer. And so, the idea of CNC machining was born. In the early 1950s, Richard Kegg worked …

HISTORY In 1775, John Wilkinson- cannon boring machine (lathe). In 1881, Eli Whitney- milling machine. In 1947, Mr. John Parsons began experimenting for using 3-axis curvature data to control the machine tool motion for the production for aircraft components. In 1949, parsons- first NC machine. In 1951, MIT was involved in the project. In 1955, after refinements NC became …

Importantly, the machine didn't just make a series of cuts at specific points, as originally proposed by Parsons, it traversed between points, milling a smooth surface in the desired shape. The demonstration project was conducted using a Cincinnati Milling Machine Company Hydro-Tel machine dolled up with gears and servo-motors to replace the ...

To accomplish this, Parsons purchased a Cincinnati DK Series, 28-inch Hydro-tel verticle-spindle contour milling machine consisting of a table and spindle that moved along X, Y and Z-axes. Over the next two years, the Cincinnati was disassembled, …

machine which was made by John T. Parsons during the years 1940's and 1950's. This invention was a step forward that headed the way to the various automated machines present in the modern day. Moreover, when John Runyon produced punch tapes under the control of the computer, it showed dramatic results with a considerable reduction in the duration of …

Parsons and Mr. Stulen proceeded to generate a two-axis airfoil machining path set of data with a factor entered for cutter diameter offset. The XY machining coordinate tables were taken to a plain Bridgeport milling machine where the X points were called out to one operator who ran the X-axis handwheel and the Y-axis to a second operator who ...

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).

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.

•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.

1949 Negotiated and executed the contract on behalf of Parsons Corporation with US Air Force to build the first numerical control milling machine. Coordinated its development with Parsons staff and principal subcontractors: IBM, Snyder Corporation, and Massachusetts Institute of Technology. Monitored design and completion of machine, 1950-1952.

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 ...

A still further purpose is to provide a machine tool with capability for programmed milling according to two new procedures, namely: (1) around the leading and trailing edges of a blade, one of whose principal surfaces is supported in a meltable matrix chuck, and (2) in cuts not taken chord-wise but arcuately about an axis of rotation spaced ...

John T. Parsons, together with Frank L. Stulen, pioneered CNC when they devised a method for machining the curves of helicopter blades, a/k/a "rotors". They generated numbers for complex and precise machining system outputs, subsequently turning to Gordon S. Brown's Servomechanisms ("servos") Laboratory at MIT to develop a feedback ...

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.

MIT's research into NC machines changed Parsons's initial use of a boring machine to a miller. The milling machine created long, continuous cuts in the working piece. The amount of setup and programming required for these NC machines required as much or more labor than the manual operation of similar equipment.
