Therefore,when the tool’s overhang ratio (cutterdiameter-to-length)exceeds6:1,special care should be taken with J the revolution speed. (At first, start the machining at 50 % of the speed shown in the table of the standardcutting conditions, and then graduallyincrease the speed whilst confirmingsafety.)
