Technical Information
Calculation of the average chip thickness in relation with the ae (Radial Engagement) if ae is less than 50% of dia.
Formula: Programme Feed Rate (fz) hm = Average chip thickness Formula: Average Chip Thickness (hm)
ae = Radial engagement
fz = hm x d fz = Feed per tooth hm = fz x ae
ae d = Cutter diameter d

Example: A 50mm diameter cutter using 5,00mm radial engagement (ae) = 10% of the cutter diameter.
At 10%, your coefficient is 1,66 (see above table); therefore you must multiply your feed rate by 1,66 for correcting the feed for profiling.

The 5230VS cutter series is designed with
wiper pockets which provide a much better
face surface finish. The non-wiper pockets
generate the 90° corner. The same inserts
can be utilised in all pockets.
