When depth of cut is lowered, feed rate can be increased further. 2. If the machine cannot achieve the recommended spindle speed, please use the max. spindle speed I available. In this case, lower the feed rate by the same ratio. ap 3. If cutting noise and vibration are present, please change the cutting conditions accordingly.
