Tool wear behavior of cemented carbide with speed For a cutting tool made of cemented carbide, at which cutting speeds does wear occur fastest? Choose the most appropriate range.
Mechanical Engineering
Production Engineering
Difficulty: Easy
Choose an option
-
ASlow speeds
-
BMedium speeds
-
CFast speeds
-
DVery fast speeds
Answer
Correct Answer: Very fast speeds
Explanation
ConceptCarbide tools withstand higher speeds than HSS, but tool wear still accelerates with increasing cutting speed (Taylor's tool life relation: V Tn = C). At the highest speeds, thermal and diffusion wear mechanisms dominate.
Final AnswerVery fast speeds.
