In case of vibration, reduce R.P.M and feed rate by the same ratio Cutting condition by overhang Cutting conditions of the shank taper type in case of being clamped at neck. When the overhang is increased by 1D, decrease R.P.M and feed 10%. In case of the straight type adjust conditions according to the overhang. Ex) When the overhang is 3D and is increased by 1D, decrease R.P.M and feed 10% Notice ± Cutting conditions are up to the machine’s condition and the shape of cutting. Use cutting fluid that is proper to the workpiece and produces few temperature reaction. Endmills 14
