When machining with peripheral cutting edges, use the minimum feed rate as a guide. Note 2) If the depth of cut is smaller than this table, feed rate can be increased. I Note 3) When contour milling, cutting conditions can vary greatly due to the geometry of the work material and depth of cut. SOLID END MILLS Note 4) If the rigidity of the machine or the work material installation is very low, or chattering is generated, please reduce the revolution and the feed rate proportionately. I119
