Cutting Recommendations for the HELIQUAD-12 Complete Line
• The table below defines initial feed rates
• For initial cutting speeds, refer to ISCAR’s recommendations for carbide grades
Calculating cutting feed rate:
ƒz=ƒz0×Kef×Ks where
fz0 - Basic feed (Table 1),
Kef - Engagement factor ( Table 2),
Ks - Stability factor (Table 3)
