eng.milling-chip-load-MRR Calculator
Calculates milling chip load, material removal rate (MRR), and spindle power from cutter geometry and feed per tooth. Chip load is the key machining parameter — too low causes rubbing and work hardening; too high causes excessive cutting force and tool breakage.
Inputs
F Ipm
Amount per unit of time or per unit quantity. Check the denominator before interpreting.
N Flutes
Count of items or occurrences.
N Rpm
Rate of movement. 1 m/s = 3.6 km/h = 2.237 mph.
D In
Distance across a circle through its centre. Always confirm units match the rest of the calculation.
Doc In
Vertical extent downward, or thickness of a layer. For tanks: affects pressure at the base (P = ρgh).
Results
chip load per tooth (in)
Sample size or count used in the calculation.
surface feet per minute SFM
Sample size or count used in the calculation.
material removal rate MRR (in³/min)
MRR (monthly recurring revenue) -- total predictable monthly subscription income. MRR x 12 = ARR.
chip load = f/(N×n)
Sample size or count used in the calculation.
typical chip loads
