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% |
| Ap1 = 0,5mm | 0,59mm | 0,42mm | 0,34mm | 0,30mm | 0,26mm | 0,19mm |
| Ap1 = 0,75mm | 0,50mm | 0,36mm | 0,29mm | 0,25mm | 0,22mm | 0,16mm |
| Ap1 = 1mm | 0,42mm | 0,30mm | 0,24mm | 0,21mm | 0,19mm | 0,13mm |
| Ap1 = 1,5mm | 0,34mm | 0,24mm | 0,20mm | 0,17mm | 0,15mm | 0,11mm |
| Ap1 = 3,5mm | 0,22mm | 0,16mm | 0,13mm | 0,11mm | 0,10mm | 0,08mm |

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:
% of Ap1 max % of vc
L/D ratio to reduce to reduce
L

D
| L/D ratio | % of Ap1 max to reduce | % of vc to reduce |
| 0% | 0% | |

| >4 | 80–95% | 20–40% |
