Which operation would a CNC machining center typically perform that a simple drill press cannot?

• A. Drilling only
• B. Tapping
• C. Milling with multiple axes and complex toolpaths
• D. Reaming

Answer: (C)

The important idea here is that a CNC machining center can move the cutting tool in multiple directions and follow programmed toolpaths to remove material in complex ways. This allows milling features such as pockets, slots, contours, and 3D surfaces, all in one setup. A simple drill press, on the other hand, has a fixed spindle and is mainly used for hole-making by plunging straight down, without coordinated multi-axis motion or complex paths.

So the operation a CNC machining center can perform that a drill press cannot is milling with multiple axes and complex toolpaths. (Drilling, tapping, and reaming can be done on various machines, but milling with multiple axes and CAM-designed toolpaths is the key capability that’s beyond a basic drill press.)
