In case of vibration, reduce R.PM and feed rate by the same ratio O Cutting condition by overhang For shank taper type, Cutting conditions are based on the case of being clamped at neck part - When the overhang is increased by 1D in comparion to the overhang, decrease R.P.M and feed by 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 by 10% O 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 reactions 0D Endmill 19
