M4E #51: What is CNC Machining and How Does it Work?
CNC (Computer Numerical Control) machining is a manufacturing process where computerized systems are used to control machine tools (typically drills or mills). It is a highly precise and automated method of fabricating parts and components from various materials, such as metal, plastic, wood, and composites.
The next video from Concerning Reality does a great job explaining how this industrial process works.

If we go back in time almost to the beginning of M4E, we have talked about plant layouts in M4E #3. What types of layouts do you think are best fitted for CNCs?
CNC machines often have automatic tool changers (ATCs) that can change tools during the machining process without manual intervention. This enables the machine to perform a variety of operations with different tools, reducing setup time and increasing efficiency as well as different processing techniques for the same piece.
The tool you can see in the video approximately between 5:34 and 5:40 is a probe. It refers to a specialized device or sensor used for measurement and inspection purposes. It’s commonly used to gather precise data about the workpiece, tool, or machine setup. Probes enable CNC machines to perform tasks such as part alignment, tool length measurement, workpiece surface scanning, and tool breakage detection.
