Which machines were used to manufacture parts for the Mars rovers?

Groups:

(a) Machines Used

,

(b) Machines NOT Used

• CNC machining center

• lathe

• horizontal milling machine

• vertical milling machine

• AutoCAD fabricator

Milling, CNC, and lathe machines operate by subtractive technology, whereas 3D printers operate by additive technology. Explain how these two technologies work. You need to include specific knowledge from today's lessons.
