Additional Application Advice • M270 High-Feed
Applying High-Feed Tools
The high-feed concept bases its strategy in small depth of cut and high fz values, which results in a higher MRR and productivity with low radial forces.
Ap1 max
Small Ap1 values and higher feed rate generate lower cutting forces versus traditional milling strategies.
Recommended when long overhang is necessary due to lower radial forces. Maximum L/D ratio of 10 x D.
Rt
For CAM programming, the tools can be
| % of Ap1 max | % of vc | programmed as a toroidal tool type by | |
| L/D ratio | to reduce | to reduce | using the Rt value as the insert radius. |
| <4 | 0% | 0% | |
| 4<L/D<7 | 55–65% | 10–15% | |
| >8 | 65–75% | 20–30% |

NOTE: Use two effective teeth for feed calculations. For materials above 45 HRC, we recommend adjusting the ae max to 55% of cutting diameter and using no more than 50% of Ap1 max. While centre cutting is possible, we recommend using a ramp angle of 0.5°–1.0° to ensure smooth operation.
