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 = 1mm | 1,01mm | 0,77mm | 0,63mm | 0,55mm | 0,49mm | 0,35mm |
| Ap1 = 2mm | 0,77mm | 0,55mm | 0,45mm | 0,39mm | 0,35mm | 0,24mm |
| Ap1 = 3mm | 0,63mm | 0,45mm | 0,37mm | 0,32mm | 0,28mm | 0,20mm |
| Ap1 = 4mm | 0,55mm | 0,39mm | 0,32mm | 0,27mm | 0,24mm | 0,17mm |
| Ap1 = 5mm | 0,49mm | 0,35mm | 0,28mm | 0,24mm | 0,22mm | 0,15mm |
| Ap1 = 6mm | 0,45mm | 0,32mm | 0,26mm | 0,22mm | 0,20mm | 0,14mm |

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

| L/D ratio | % of Ap1 max to reduce | % of vc to reduce |
| 0% | 0% | |
| 2 | 65–75% | 10–15% |
| >4 | 80–95% | 20–40% |
