Difficulty: Easy
Correct Answer: Increases tool life
Explanation:
Concept/Approach
A larger end cutting edge angle reduces rubbing of the end flank against the newly machined surface, lowering frictional heating and wear.
Step-by-step reasoning
• Larger angle → better end clearance → less contact/rubbing.• Less heat at the end flank → slower wear progression → longer life.
Final Answer
Increases tool life
