The first NC machines were built in the 1940s and 1950s, based on existing tools that were modified with motors that moved the controls to follow points fed into the system on punched tape. These early servomechanisms were rapidly augmented with analog and digital computers, creating the modern CNC machine tools that have revolutionized the machining processes.

The automation of machine tool control began in the 19th century with cams that “played” a machine tool in the way that cams had long been playing musical boxes or operating elaborate cuckoo clocks. However, automation via cams is fundamentally different from numerical control because it cannot be abstractly programmed. Various forms of abstractly programmable control had existed during the 19th century: those of the Jacquard loom, player pianos, and mechanical computers pioneered by Charles Babbage and others. Whitney “Keller Machine”, which could copy templates several feet across. One barrier to complete automation was the required tolerances of the machining process, which are routinely on the order of thousandths of an inch. Although connecting some sort of control to a storage device like punched cards was easy, ensuring that the controls were moved to the correct position with the required accuracy was another issue. The key development in this area was the introduction of the servomechanism, which produced powerful, controlled movement, with highly accurate measurement information. Attaching two servos together produced a selsyn, where a remote servo’s motions were accurately matched by another. The first serious suggestion that selsyns could be used for machining control was made by Ernst F.

Alexanderson, a Swedish immigrant to the U. The birth of NC is generally credited to John T. Stulen, working out of Parsons Corp. In 1942, Parsons was told that helicopters were going to be the “next big thing” by the former head of Ford Trimotor production, Bill Stout. After setting up production at a disused furniture factory and ramping up production, one of the blades failed and it was traced to a problem in the spar.

At least some of the problem appeared to stem from spot welding a metal collar on the stringer to the metal spar. The collar was built into the stringer during construction, then slid onto the spar and welded in the proper position. That development led Parsons to consider the possibility of using stamped metal stringers instead of wood. These would not only be much stronger, but far easier to make as well, as they would eliminate the complex layup and glue and screw fastening on the wood. Duplicating this in a metal punch would require the wooden jig to be replaced by a metal cutting tool made of tool steel.

Stulen’s brother worked at Curtis Wright Propeller, and mentioned that they were using punched card calculators for engineering calculations. Stulen decided to adopt the idea to run stress calculations on the rotors, the first detailed automated calculations on helicopter rotors. Stullen had no problem making such a program, and used it to produce large tables of numbers that would be taken onto the machine floor. Here, one operator read the numbers off the charts to two other operators, one on each of the X- and Y- axes.

For each pair of numbers the operators would move the cutting head to the indicated spot and then lower the tool to make the cut. At that point Parsons conceived of a fully automated machine tool. With enough points on the outline, no manual working would be needed to clean it up. However, with manual operation the time saved by having the part more closely match the outline was offset by the time needed to move the controls. If the machine’s inputs were attached directly to the card reader, this delay, and any associated manual errors, would be removed and the number of points could be dramatically increased.
