Cutting Speed Calculation Formula
V = π × D × N / 1000
V: Cutting speed (peripheral speed), m/min
D: Outer diameter of saw blade, mm
N: Rotational speed of saw blade, min⁻¹
π: Pi≈3.14
Chip Load Calculation Formula
Fz = F × 1000 / (N × Z)
Fz: Chip load, mm/tooth
F: Feed speed, m/min
N: Rotational speed of saw blade, min⁻¹
Z: Number of teeth
Maximum Operating Speed
The table below indicates the maximum allowable RPM based on the saw blade outer diameter and body thickness.
