However, if the rigidity of the machine or the work material installation is poor, vibration or abnormal sound can occur. In this case, please reduce the revolution and the feed rate proportionately, or set a lower depth of cut. Note 2) If the depth of cut is smaller, the revolution and the feed rate can be increased. Note 3) For profile machining such as molds, machining conditions may differ considerably depending on the work material geometry, machining methods and depth of cut. Reduce the feed rate especially when machining the corner sections of a work material. Note 4) Air blow or oil mist is recommended for good chip evacuation. J057
