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 chart above shows the Wiper pockets are multiplication factor for the feed identified with a W rate based on the percentage engraved on the of the radial engagement of the face of the body. 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.
