Red Seal Tool and Die Maker Practice Exam

CNC stands for Computer Numerical Control, and this terminology is fundamental in the field of machining and manufacturing. It refers to the technology that allows computer systems to control machine tools through a process that interprets data into precise movements.

In CNC machining, a computer program using specific languages like G-code is employed to dictate the movements of machinery such as lathes, mills, and routers. This allows for high precision, consistency, and repeatability in manufacturing processes, even for complex shapes and designs. The application of CNC technology has revolutionized the machining industry by enabling automation of tasks that were once manual, significantly enhancing productivity and cutting down the chances for human error.

Understanding CNC is critical for tool and die makers, as it enables them to effectively program machines for fabricating tools, dies, and parts that meet precise specifications.
