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 the cutting conditions.
