Graphite milling, the proper way
Roughing process: fz=~ mm/tooth Finishing process: fz=~ mm/tooth For smaller or larger tools, slightly adjusting the above fz can get quite good results. For milling inserts, we recommend an fz as large as possible but below mm/tooth to make sure the graphite edge will not chip. In graphite cutting, the larger the fz, the longer the tool life. If fz is too small, then the
