In general, plunge milling is an alternate method when side milling is not possible due to vibrations. For example: When the tool overhang is greater than 4 x DC. When the stability is poor. For semi-finishing corners. For difficult-to-cut material, such as titanium. It can also be an alternative when machine power or torque is a limitation.
