Question:
5. The system gets feedback from the __________ encoder located inside the servo motors on the
machine.
Answer:
Optical
Question:
6. The __________ screw turns rotary motion from the servo motor into linear axis motion and
eliminates __________ in the CNC table drive system.
Answer:
Ball; Backlash
, Question:
7. True or False:
Fixture offset or work-coordinate systems (WCS) are the same as the world x, y, & z zero position
location in the CNC mill machine.
Answer:
False
Question:
