Which machine in the lab is not listed as CNC-automatable?

• A. Milling machine
• B. Lathe
• C. Welder
• D. Drill press

Answer: (D)

CNC automation relies on programming tool paths to control motion. Milling machines and lathes are classic CNC workhorses because they are designed to follow computer-generated paths across multiple axes for precise, repeatable material removal. A drill press, by contrast, is typically a fixed, manually fed tool used for drilling holes, with the operator guiding the feed and position rather than following a programmed path. In a standard lab setup, it doesn’t usually operate from a computer program, so it isn’t considered CNC-automatable. That’s why the drill press is the one not listed as CNC-automatable.
