What does the acronym "CNC" stand for in metal fabrication?

Computer Numerical Calculation
Computer Numerical Control
Controlled Numerical Cutting
Code Navigation Control

The correct answer is: Computer Numerical Control

The acronym "CNC" stands for Computer Numerical Control. This technology integrates computer software with machine tools to automate the manufacturing process in metal fabrication. By using CNC machinery, operators can manage the movements of a machine tool with precision using a set of coded instructions fed into the computer. CNC allows for the intricate programming of complex shapes and designs, enabling greater accuracy and efficiency than traditional manual methods. It has revolutionized the metal fabrication process as it minimizes human error, increases repeatability, and allows for the production of highly complex parts that would be difficult or impossible to create manually. Understanding CNC is essential for any metal fabricator, as it is a fundamental component of modern manufacturing practices.
