If vibrations occur make adjustments according to the machining conditions. Note 2) Note, vibrations may occur in the following conditions. • When using long tool overhang. • When pocket machining corner radii. • When the work has poor clamping rigidity or when the machine rigidity or work rigidity is low, vibrations can occur easily, if so, reduce cutting conditions such as width and depth of cut and feed per tooth.
