Rumus Perhitungan Kecepatan Potong
V = π × D × N / 1000
V: Kecepatan potong (kecepatan keliling), m/menit
D: Diameter luar mata gergaji, mm
N: Kecepatan putar mata gergaji, menit⁻¹
π: Pi ≈ 3,14
Rumus Perhitungan Pemakanan per Gigi
Fz = F × 1000 / (N × Z)
Fz: Pemakanan per gigi, mm/gigi
F: Kecepatan pemakanan, m/menit
N: Kecepatan putar mata gergaji, menit⁻¹
Z: Jumlah gigi
Kecepatan Operasi Maksimum
Tabel di bawah menunjukkan RPM maksimum yang diizinkan berdasarkan diameter luar dan ketebalan bodi mata gergaji.
