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. Wiper pockets are The chart above shows the identified with a W multiplication factor for the feed engraved on the rate based on the percentage face of the body. of the radial engagement of the cutter diameter. 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. Pockets setting difference between wiper and non- wiper inserts.
