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. A3 is the depth of cut for the full dual blade portion at the end of the cutting edge.Beyond the range of A3 where overlapping occurs, there is an 6DC area where the cutting edge becomes single bladed, not formingfull dual blade configuration. 4.5DC 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 followingdepth of cut (t), at which the edge is full dual bladed at the borderof cut, is recommended to prevent damage to the cutting edge.*DC=Cutting Edge Diameter 050%100% (inch) Feed Rate 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 *Figures for A3 and shown in the table APMX are of holder & 1.000, 1.047& 1.250, 1.297 .669─ .866.866 ─ 1.102 unstable machining.Please reduce feed accordingly, using the standard. & 1.500 1.102 ─ 1.378 above chart as a guideline.
