80_0VOD45 Technical Information

Feed rate compensation: For 42° cutting, divide the hm value by the sine of the approach angle (the sine of 42° = 0,669)

i.e.: hmor0,08
0,6690,669= 0,12mm programmed feed rate

Calculation of the average chip thickness in relation with the ae (Radial Engagement) if ae is less than 50% of Dia.
