Feed rate compensation: For 45° cutting, divide the hm value by the sine of the approach angle (the sine of 45° = 0,707)
| i.e.: hm | or | 0,08 | |
| 0,707 | 0,707 | = 0,11mm programmed feed rate |
Calculation of the average chip thickness in relation with the ae (Radial Engagement) if ae is less than 50% of Dia.
