He deserves our respect for realizing, in a general Profile of a decent man who was involved with cold war politics and Parsons aged and nearly blind, at IMTS in 1998, still presented the With Airįorce backing, MIT became known as the organization responsible for the In the end, MIT defined, invented, named, characterized, andĭisseminated NC technology with the support of the Air Force. These resources, he consulted MIT for its knowledge of servo drive He had IBM equipment, engineers, and machine operators in hisĮmploy who experimented with by-the-numbers position control. Uneducated shop floor guy who invented NC. The machining industry myth that surrounds Parsons paints him as an Reverberates in the CNC industry even today. The struggle between Parsons and MIT for control of the project Usurped by the Massachusetts Institute of Technology and redefined asģ-axis contouring motion control with a straight-line interpolation Airįorce to develop a by-the-numbers machining concept. MI, and an accomplished machinist, initiated a project with the U.S. In 1948, John Parsons, president of Parsons Works, Traverse City, RELATED ARTICLE: WHO WAS THE REAL INVENTOR OF NC? Siemens Energy and Automation, Machine Tool Business His special interest is technology on the shop Norman Bleier manages Siemens machine tool applications engineering Significant exception that the role of the operator is generallyĪcknowledged as essential for CNC success. Today, numerical control is still very much the way it wasĮnvisioned by the Air Force more than half a century ago, with the Air Force used its deep pockets to get its way, and inįact, to finance the development of computer-based workpiece programming, Computer-Aided Manufacturing-CAM-as well.

The machining required for this production requiredīy-the-numbers machining to cut contours that were impossible by manual Which required a rigid-but light-airframe for the added weight of theĮlectronic devices. Way to make parts to rigid specifications. The Air Force wanted to remove the machinist from the machining process,īelieving that human-free by-the-numbers machining was a more reliable Air Force, sponsor of the GE effort, declined the use ofįirst, the machinist was the "programmer" in this method. Recording was played back to power actuators that drove the lead screws To a recording device as the machinist made the first part. The GE engineers fitted position transducers on the Numerical control, General Electric was working on a process known as
In the early '50s, while professors at MIT were developing Numeric form for numerically-directed interpolation of a cutting tool in Laboratory at the Massachusetts Institute of Technology in Boston inĬomputer Numerical Control-CNC-like NC, is the separation of World's first NC machine tool demonstrated by the Servo Mechanisms
Numerical Control technology-NC-is the direct descendent of the Numerical Control and Computer Numerical Control. While we mourn Parsons' death, he leaves the legacy of It's because Parsons was the father of numerical control.
