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 10% 20% 30% 40% 50% 100%
Example application
Ap1 = 0,5mm 1,18mm 0,70mm 0,63mm 0,56mm 0,50mm 0,35mm highlighted.
Ap1 = 0,75mm 0,95mm 0,62mm 0,56mm 0,50mm 0,45mm 0,30mm
Ap1 = 1mm 0,80mm 0,57mm 0,46mm 0,40mm 0,36mm 0,25mm
Ap1 = 2mm 0,57mm 0,40mm 0,33mm 0,28mm 0,25mm 0,18mm
Ap1 = 3mm 0,46mm 0,33mm 0,27mm 0,23mm 0,21mm 0,15mm
Ap1 = 5mm 0,36mm 0,25mm 0,21mm 0,18mm 0,16mm 0,11mm

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:
