Salmon's hypothesis relates between
- A. Surface finish and cutting tool geometry
- B. Cutting forces and surface finish
- C. Cutting speed and cutting temperature
- D. Surface finish and cutting temperature
Answer: C. Cutting speed and cutting temperature
Explanation: Salomon's (often referred to as Salmon's) hypothesis forms the theoretical basis for High-Speed Machining (HSM). It postulates a relationship between cutting speed and cutting temperature, suggesting that beyond a certain critical cutting speed, the cutting temperature at the tool-chip interface actually begins to decrease rather than increase.
