Which machines could be automated via CNC technology in the lab?

• A. Milling machine
• B. Lathe
• C. Welder
• D. All of the above

Answer: (D)

CNC automation relies on computer-controlled guidance to move tools and perform operations with precision and repeatability. A CNC setup can direct the motion of a milling cutter for complex profiles, control the rotation and feed of a turning spindle, and coordinate a welding torch or robotic arm to follow a programmed weld path. Because each of these machines supports computer-driven control, all of them can be automated. Milling machines become CNC mills, lathes become CNC lathes, and welding processes can be automated with CNC welding systems or robotic welders. So, all of the above is the best answer.
