� th = waktu potong efektif ( menit )

� L = panjang langkah total ( mm )

o La = panjang langkah awal ( mm ) = 2 mm

o Ls = panjang point twist drill ( mm )

o Lw = kedalaman lubang ( mm ).

� Untuk lubang tembus, Lw = tebal benda kerja.

o Lu = panjang langkah akhir ( mm ) = 2 mm

� Untuk lubang tidak tembus, Lu = 0

� i = jumlah pengulangan pengeboran

� vf = kecepatan pemakanan ( mm/menit )

� s = feeding ( mm/putaran )

� n = putaran spindel ( rpm)

� cs = kecepatan potong ( m/menit )

� d = diameter twist drill ( mm )
