Spindle Power Calculator

Spindle power (P_s):

Cutting force (F_e):

Cutting speed (v_e):

Efficiency of the spindle drive (η):

How This Is Calculated

$$ P_s = \frac{F_e \cdot v_e}{60 \cdot \eta } $$ where:

P_s = Spindle power (W)

F_e = Cutting force (N)

v_e = Cutting speed (m/min)

η = Efficiency of the spindle drive (typically 0.7-09)

Assumptions

Cutting conditions remain constant.
Tool engagement/disengagement are not considered.
Heat and friction effects are ignored.
Properties of the material are unifrom.
