  • +RZWRVHWFXWWLQJFRQGLWLRQVRQGL௺HUHQWRYHUKDQJOHQJWK The recommended cutting condition is depended by the L/D factor. L/D ratio table : EX :

Tool : Ød=12mm Square Head

L/DVC (m/min)fz (mm/t)ae (mm)
2 ~ 3100%100%100%
4 ~ 570%80%50%
6 ~ 750%70%30%
8 ~ 940%60%20%

L/D : 50/12 = 4.16

Application : Shoulder Milling

Cutting condition is recommended as :

fz = 0.05*80% = 0.04 mm/t

max ae = 2.4*50% = 1.2 mm
