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.

Difficulty: Easy

Slow speeds
Medium speeds
Fast speeds
Very fast speeds

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.
