Note 2) When using the G1-breaker wiht coated grades VP15TF, MP6120 or MP9120, reduce the feed rate by 20%. Note 3) For more information on "No.", please refer to page L201 for cutting speed. INDEXABLE MILLING A3 is the depth of cut for the full dual blade portion at the end of the cutting edge. 6DC Beyond the range of A3 where overlapping occurs, there is an area where the cutting edge becomes single bladed, not forming Overhang 4.5DC full dual blade configuration. BT50 As such, please pay special attention to the relationship between 3DC depth of cut and feed. BT40 In general, the edge at the border of cut tends to suffer from 1.5DC HSK63 damages. At large depth of cut operations, applying the following depth of cut (t), at which the edge is full dual bladed at the border of cut, is recommended to prevent damage to the cutting edge. *DC=CDiameter utting Edge 0 50% 100% APMX Feed Rate A3 (inch) t Tool Diameter Recommended Depth of Cut t Chatter vibration and other problems tend to  & .625, .672 .472 ─.551 occur at operations where overhang length is & .750, .797 .551─.669 large and/or machine rigidity is low, resulting in unstable machining. *Fshown igures for A3 and APMX are & 1.000, 1.047 .669─ .866 in the table of holder & 1.250, 1.297 .866─1.102 Please reduce feed accordingly, using the standard. & 1.500 1.102─1.378 above chart as a guideline.
