When Did CNC Machining Start?

CNC machining began as a way to make precise parts and improve the productivity of a manufacturing process. MIT's Parsons worked on a prototype of the machine in the 1950s. This machine was powered by motorized axes and programmed using a punch tape system. In 1958, Kegg and MIT worked to develop the first numerically controlled milling machine. Their research resulted in the first computer-controlled CNC milling machine.

Early CNC machining was controlled by camshafts with grooves. The machine would automatically run when it read the numerical coordinates. This process was incredibly efficient for repetitive unmanned tasks, including carving gun stocks during World War I. This method was not a true numerical control, though: there was no way to reposition the cutting tool to change its position. With the help of CAD and CNC software, designers could program their designs with just a few mouse clicks.

The first CNC machining machines used a hand-held computer. The first one was a prototyping model of a 28-inch vertical spindle contour milling machine. The prototype was patented in 1959. The computer was controlled by a vacuum tube and eight-column paper tape. In the beginning, CNC machines were controlled by punched tape, which was also used for telecommunications. After the rise of digital technology, the "by-the-numbers" method was replaced.

CAD and CNC machining are two related technologies. CAD and CNC started in the 1950s. MIT developed the first CAD program, which allowed designers to draw their parts directly on a computer interface, bypassing the need for paper-based drafting. This technology quickly spread and became widespread. Today, CNC machining is one of the most advanced methods of manufacturing. Its benefits are limitless.

CNC machines are the backbone of modern manufacturing. They use the technology of turning machines, which dates back to the 18th century. The first CNC milling machine was invented in 1952 by John Parson. MIT researchers first used the computer for turning metal in the late 1940s. The use of this new technology was popularized in the 1960s. The invention of the Swiss jig borer was a precursor to CNC machining.

The first CNC machine was used in the 1960s to make helicopter blades. In the 1980s, the development of CNC machines continued to progress as computer technology matched the technology. The development of CNC machines in the 1960s has been a major step forward for manufacturing. A CNC machine has become the mainstay of the modern manufacturing industry. The technology is widely used today in industries as diverse as aerospace. Once it is installed in a company, the benefits can be exponential.

CNC machining is a method that uses a technique developed in the 18th century. In the 17th century, a mechanically controlled turning machine was invented, which gave rise to the second-half of the acronym CNC. NC machines were the first machines to use computers, which later became common. It made manufacturing more efficient. Nowadays, CNC equipment is used to produce more parts than a human artisan ever could.
