・The above recommended cutting conditions may require adjustment according to machine rigidity and work rigidity. The above figures are guidelines for use with the BT50 machine tool. ・The above cutting conditions assume a tool overhang length of L/D=3 (i.e. overhang length is 3 times tool diameter) or less. When tool overhang is more than L/D=3 and less than or equal L/D=5, settings should be adjusted to approximately 70 to 80% of those indicated in the above cutting conditions (i.e. a and f ). p z When tool overhang is more than L/D=5 and less than or equal L/D=8, settings should be adjusted to approximately 50 to 60% of those indicated in the above cutting conditions (i.e. a and f ). p z
