# Cutting power and spindle torque
# Scope: Material-removal power from supplied specific cutting energy; not a material lookup.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

removalRate = 5 cm^3/min
specificEnergy = 2 J/mm^3
efficiency = 0.8

cuttingPower := removalRate*specificEnergy [W]
inputPower := cuttingPower/efficiency [W]

check spindle power budget: inputPower <= 300 W

scenario alternative: removalRate = 4 cm^3/min
