It is well known that roughing end mills have various excellent points, such as less cutting power, less cutting vibration and easier chip treatment than regular end mills. However, the reason of a roughing end mill being able to save the cutting power is not made sufficiently clear yet. The optimal dimension of the cutting edge shape is also unknown. In this report, characteristics of chip forming mechanism of roughing end mills are described and the cutting power saving in roughing end mills being derived from the higher feed rate is also explained. Moreover, it is theoretically shown that the cross-section shape of chips is changed by the cutting edge radius, the pitch of the wave-form edge and the feed rate. Considering from this cross-section shape of chips, small cutting edge radius and long pitch of the wave-form edge are recommended. The appropriateness of this recommendation is shown experimentally.
