2) When using both Main and Sub spindles In this case, when the cutting edge runs beyond the center line, the insert will contact the workpiece, since the workpiece does not fall off. e.g.) When the cutting edge is programmed to run 1mm beyond the center. Workpiece maximum, D2 (Fig.4) ct>Dmax-1mmx2 (mm) (The clearance between the insert and the workpiece is 0.2mm) Main Spindle Sub Spindle w Fig.3 (When the edge is at the center) (When the edge is 1mm beyond the center) Tough Edge, T-Chipbreaker Fracture resistance comparison (Interruption) Cutting Edge (Front Relief Surface) T-Chipbreaker (PR1225) 3,000 passes Competitor C 700 passes Competitor D 3,000 passes 1,000 passes 2,000 passes 3,000 passes Tough Edge, T-Chipbreaker (PR1225) Competitor C X Competitor D X Vc=80m/min f=0.05mm/rev (At Cut-off: 0.015mm/rev) Wet Workpiece material: SK4 Workpiece (with flat cuts on two sides) TKF12R200-T-16DR (PR1225) Compared to Comp.
