Taylor's tool life exponent n for carbide tools in VTⁿ = C For carbide cutting tools in the Taylor tool-life relation, what is the typical range of the exponent n? Choose the correct range.

Q: Taylor's tool life exponent n for carbide tools in VTⁿ = C For carbide cutting tools in the Taylor tool-life relation, what is the typical range of the exponent n? Choose the correct range.

Reference values Typical exponent n by tool material: HSS ≈ 0.08–0.20; Carbide ≈ 0.20–0.25; Ceramics ≈ 0.4–0.55. Hence the correct band for carbides is 0.20–0.25. Final Answer 0.20 to 0.25.

Difficulty: Easy

0.10 to 0.20
0.20 to 0.25
0.25 to 0.40
0.40 to 0.55

Correct Answer: 0.20 to 0.25

Explanation:

Reference values
Typical exponent n by tool material: HSS ≈ 0.08–0.20; Carbide ≈ 0.20–0.25; Ceramics ≈ 0.4–0.55. Hence the correct band for carbides is 0.20–0.25.

Final Answer
0.20 to 0.25.
