eng.machining-cutting-speed Calculator
Calculates optimal cutting speed for metal machining from Taylor's tool life equation and target tool life. Taylor's tool life equation (VT^n = C) shows that cutting speed and tool life are inversely related — doubling the cutting speed typically reduces tool life by 8–32× depending on the Taylor exponent n.
Inputs
D Mm
Distance across a circle through its centre. Always confirm units match the rest of the calculation.
Rpm
Rate of movement. 1 m/s = 3.6 km/h = 2.237 mph.
Feed Mm Rev
Amount per unit of time or per unit quantity. Check the denominator before interpreting.
Depth Mm
Vertical extent downward, or thickness of a layer. For tanks: affects pressure at the base (P = ρgh).
Results
cutting speed Vc (m/min)
The computed rate of movement or processing.
material removal rate MRR (mm³/min)
MRR (monthly recurring revenue) -- total predictable monthly subscription income. MRR x 12 = ARR.
Vc = π·D·n
Sample size or count used in the calculation.
MRR = Vc·f·d
MRR (monthly recurring revenue) -- total predictable monthly subscription income. MRR x 12 = ARR.
recommended Vc by material
The value at the specified point or condition.
