Calculation method
Calculation method
Estimated life at supplied speed (min)
T=(C/V)^(1/n).
Speed for desired life (m/min)
V=C/(desiredLife^n).
Desired-life speed inside fit range
Yes iff minSpeed<=calculatedSpeed<=maxSpeed; otherwise Outside fitted range.

Assumptions & limits
Assumptions & limits
- Taylor power-law interpolation from explicitly supplied empirical constants for a single tool/workpiece/criterion combination. No default supplier recommendation or machining safety inference. Supported limits: n,C,V,T>0; minSpeed<=V<=maxSpeed; bounded finite exponent result; desired speed out of range flagged.
