What is the function of a CNC machine?

• A. To create manual control for machining tools
• B. To automate control of machining tools via computer programming
• C. To test the hardness of materials
• D. To operate lathes manually

Answer: (B)

A CNC (Computer Numerical Control) machine is designed to automate the control of machining tools through the use of computer programming. This technology allows for precise control over the movement and operation of the machine, making it possible to produce complex geometries and high-quality parts with minimal human intervention. Programs written in specific languages guide the CNC machine to execute a series of machining operations, such as milling, turning, drilling, or cutting, accurately and consistently. The automation aspect is crucial because it significantly increases production efficiency and reduces the likelihood of human error, which can occur in manual machining operations. CNC machines can repeat tasks reliably and are ideal for producing high volumes of parts with tight tolerances. This capability sets CNC technology apart from manual machining methods, where an operator must physically control the machinery. In the context of the other options, manual control of machining tools does not leverage the precise programming that CNC offers, testing the hardness of materials is unrelated to the functions of CNC machinery, and operating lathes manually does not utilize the automation benefits that a CNC machine provides. Therefore, the correct answer emphasizes the essential defining function of CNC machines in the machining industry.
