Note 1) When cutting austenitic stainless steel, the use of water-soluble cutting fluid is especially effective. Note 2) If the depth of cut is smaller than this table, feed rate can be increased. Note 3) The irregular helix flute end mill has a large effect on controlling vibration when compared to standard end mills. However, if the rigidity of the machine or the work material installation is very low, then vibration can occur. In this case, please reduce the revolution and feed rate proportionately, or set a lower depth of cut. I I243
