CNC machining, or Computer Numerical Control machining, represents a significant development in manufacturing technology. This method effectively removes material from a workpiece by using computerized systems to accurately regulate the movement of tools and machinery. As a result, CNC machining creates superior parts with complex geometries that are challenging to accomplish with conventional techniques. Key advantages of this technology include enhanced speed, improved accuracy, and the capability to create complex designs with minimal human intervention.

CNC Machining originated in the 1940s and 1950s, driven by the requirement for accuracy and precision in manufacturing complex components, particularly for the aerospace industry. The development began with John T. Parsons, who created early numerical control systems using punched cards to guide machine tools. This evolved into CNC technology in the late 1950s, which replaced manual controls with computer-generated instructions, significantly enhancing flexibility and accuracy. The introduction of CAD (Computer-Aided Design) and CAM (Computer-Aided Manufacturing) systems in the 1960s and 1970s further revolutionised CNC machining, allowing for intricate designs and efficient production processes.

As CNC technology continued to advance, it profoundly impacted modern manufacturing practices and has been shaping them ever since. One of the significant technological innovations is the development of 5-axis CNC machines. These machines allow for complex shapes to be machined with high precision, enabling manufacturers to produce intricate components with complex geometries mostly in a single setup that were previously challenging to produce. The degree of flexibility that CNC machining technologies offer in terms of production and quality requirements is unparalleled for any scale of production.
