Selecting the Correct Cutting Values
1. fz depends on the Ap1 and ae values
With round inserts, two factors can affect the hm: Ap1 and ae.
fz has to be adjusted accordingly.
Recommended Starting Feed Rate Values (fz) Related to the Ap1 and ae Values:
ae engagement
Ap1 = 1mm
Ap1 = 2mm
Ap1 = 3mm
Ap1 = 4mm
Ap1 = 5mm
Ap1 = 6mm

2. Ap1 and vc corrections depend on L/D ratio
With increasing L/D ratios, or overhang, vibrations can occur due to reduced
rigidity. To ensure successful application, it is recommended to adjust Ap1
and vc values according to the following table:
