CNC (Computerized Numerical Control) machining is a highly advanced manufacturing technology. It allows you to use pre-programmed systems to control the machine tools, like mills, lathes, and grinders, for detailed and complex cutting. Since shaving off materials and turning them into useful products is not possible by hand.
CNC machining programming is the heart of it. A technician designed a computer program that was part of CAD software and typed detailed instructions into it. The machine tool is guided along with every movement and operation exactly as it should be once this program is running. More than that, this innovative approach elevates the manufacturing’s capability and improves productivity and efficiency.

CNC History Overview
CNC has a rich and fascinating history of human ingenuity and technological advancement, with a context that is equally important for its future development in manufacturing. The first CNC machine revolutionized the production line and the workflow. An understanding of the origins of CNC tech also brings into focus its stream toward improvement. This also instills us with confidence that the future advances in this technology will be quite awesome.
How and Where CNC Machining Began
The Second World War inspired the history of CNC machining. This technology was developed because of the demand for complex and exact machinery parts, especially in the aerospace industry. Because production of high-quality components for the war required the expediency that only automated methods could produce, innovators began examining automated solutions.
Numerical control (NC) technology was introduced by American engineer John T. Parsons in the 1940s to begin the genesis of the CNC machining process. In designing the first numerically controlled machine together with MIT, he served in the U.S. Air Force. Precise control of re-running the manufacturing operation was achieved using punched tape with the machine.
In the 1950s, MIT engineers used servo motors to improve the operation speed on NC machines. The modern CNC technologies were first demonstrated to the industries with the use of the first computer-controlled machines. The addition of motor-controlled apparatus and numerical control systems is an important step in the history of manufacturing, as machines can perform operations based on preprogrammed instructions.
Evolution of CNC Technology
CNC machines have a unique evolution. Enigmatic would be, to begin with a machine controlled by a punch card and end up with a machine controlled by digitally powered software. The evolution was the cause of CNC machining becoming faster, more precise, and more accurate than NC. Technological advancements contributed to the development of the first CNC machine.
From the 1960s and ‘70s, the production of CNC machining revolutionized the minimum computers and advanced programming languages. The implementation of G-code as their standardized programming language gave machinists more programming flexibility.
The decisive milestone of CNC machining was reached by the 1980s. By integrating microprocessors into personal computers, manufacturers worldwide gained access to universal usage of CNC machines. CNC technology immediately made the jump to the automotive industry and the aerospace sector because it gave them accurate processing and the ability to manufacture components automatically with minimal turnover.
