<<Continued from The History of CNC Technology, Part I>>

 Modern CNC Manufacturing Is Born

Parsons developed these processes while working on a contract for the U.S. government. Once Washington, D.C. got word of this technology, they began to take interest. It was not long before this technology was producing far more than just helicopter rotor blades for very long. 

In 1949, the U.S. Air Force began experimental research into the various capabilities of CNC technology. During this time period, tensions between the U.S. and the Soviet Union were at a fever pitch, the Red Scare had polluted America. Several government officials were unmasked as Soviet spies and the nation became increasingly paranoid about its military might against a looming Communist threat. 

 Though there were many motivations for interest in CNC manufacturing methods, the United States Defense Department was undoubtedly hopeful that this new technology would provide a much needed advantage over the Soviet military by increasing efficiency and decreasing costs. 

The Air Force built on Parsons’ work by overseeing a series of research projects in conjunction with the prestigious Massachusetts Institute of Technology. Together they worked to expand the technology even further. This made way for lots of firsts. During a series of tests, a mechanism for determining how far the controls actually turned was invented. Along with the development of the APT (automatic Programmed Tool) …. During the course of the MIT studies, engineers became confident they could produce different complex cut(s) that could not be duplicated manually. 

The sum total of the work begun by Parsons and expanded by the Air Force and MIT was a prototype for modern CNC machining. This new machine used a tape reader and vacuum-tube electronic controls, among many other features, to do the work 

Further Advances & Patenting

By 1953, the technology had stretched to a new level of expansion with the creation of the Numericord controller. This controller took the place of the punch tape. A fully automated version would follow in 1957. 

Parsons saw the Motor Apparatus for Positioning Machine Tool, which was awarded to him in 1958. The capital generated from the patent was able to sustain Parsons’ later work developing CNC technology, despite skyrocketing costs in the late 1950s and 1960s. Without this foresight there’s no telling where the technology would be today. 

It wasn’t until the late 1960s and early 1970s that the modern CNC technology most contemporary operators would recognize began to take shape. Digital processes began making their first appearances. Although the technology has come a long way, the basic concept, of a mill operating along several axes, directed by servo motors, remains pretty much the same. 

 Common Elements of CNC Technology

The command function on a CNC machine does not have to be the most complicated piece of equipment in the world. In fact, it can even be a simple cam system[TK4] . On the more sophisticated end of the spectrum, it could be a fully digital interface. But the three elements that all CNC technology has in common are the command function, the drive/motion system, and the feedback system. 

The command function originates from the operator. These programs typically include motion type, the axes on which the motion should be executed, the amount of motion and motion rate.   

The motion / drive system consists of an electric or hydraulic motor and any combination of clutch, cylinder, or brake. The entire purpose of this piece of equipment is to propel motion. 

The final piece is the feedback system. In the early days of CNC technology, this was a synchronous motor. Today, it is more often than not a set of digital encoders used to create synchronous motion. 

CNC Then & Now

There are a number of differences between the computer numerical control of the early days and now. Dissecting those differences helps us better understand and appreciate how far technology has come. It may even give us a window into what the next innovations may be. 

These days, CNC machining has infiltrated all types of industries through an extremely unique medium and has had resounding impacts on a number of processes. 

The Future of CNC 

Modern CNC machining has sprawled across so many industries that it is sometimes hard to keep track of it all. 

From aerospace to medical devices, firearms to electronics, CNC machines are even becoming popular with many DIY home users. Despite coming from humble origins, CNC manufacturing will continue to be just as eminent in the next century as it was in the last. 

Increasingly, CNC manufacturers are looking to integrate their capabilities with robotic technology to provide more cohesive production processes. As this integration progresses, CNC operators will be able to control both CNC machines and robots from the same control panel. Programs will operate using simpler languages and continue to become increasingly more efficient. It’s an amazing new development with plenty of more exciting things to come. 

There are other minute details that can be improved to maximize the potential of this method. The life time of spindles, the secure clamping of tools and the overall lifetime of tools used for cutting processes could all be advanced in the years to come to ensure that manufacturers are getting the most out of their investment.  

Personalization is another feature that will gain wider acceptance as we move further into the 21st Century. With the dramatic decrease in costs to produce CNC machines, more and more people will be purchasing and using these in unique and resourceful ways. This will lead to new and innovative niches and cottage industries and a greater acceptance of CNC tech in everyday life. 

The Legacy of John Parsons

While CNC manufacturing methods having made enormous strides, the contributions of Parsons and his team will never be forgotten. With his integral role in the origins of CNC technology, Parsons was honored as the Father of the Second Industrial Revolution by the Society of Manufacturing Engineers in the late 1960s. He was also inducted into the National Inventors Hall of Fame in 1993. He passed away in 2007.
