Difficulty: Easy
Correct Answer: Agree
Explanation:
Introduction / Context:
Milling has two principal modes: conventional (up) and climb (down). The terminology varies by region and text, so recognizing equivalence avoids confusion in setup and process planning.
Given Data / Assumptions:
Concept / Approach:
In up/conventional milling, the cutter teeth engage at zero chip thickness and exit at maximum thickness, and the cutting force tends to lift the work. In down/climb milling, engagement starts at maximum chip thickness and decreases to zero, with a seating force component.
Step-by-Step Solution:
Identify synonym pair: up milling ≡ conventional milling.Recall chip thickness progression and force direction.Confirm equivalence and select “Agree”.
Verification / Alternative check:
Process planning texts and machine manuals use both terms interchangeably; many note backlash concerns for climb milling.
Why Other Options Are Wrong:
“Disagree” is incorrect based on standard terminology. The equivalence is not limited to vertical mills or specific cutters.
Common Pitfalls:
Mixing force/finish advantages of climb milling with the naming of up milling; they are distinct modes.
Final Answer:
Agree
