RCN = distance from centre line to the start of the cutting edge. This dimension can also help determine the minimum circle size when helical ramping. R = the head radius size. R¡ = the shoulder radius or radius at the corner of the cutter. „Programming Data Tool List 70N7 Ramping Guide for Circular and Linear Interpolation Geometrical Parameters Circular Interpolation Linear Interpolation Allowed Range of Calculated Length (mm) per Ramp Angle Hole Diameter diameter Ap1 max Rfm Rt Rc Xfm Yfm YD Number Ramp Angle (degree) [mm] [mm] [mm] [mm] [mm] [mm] [mm] [mm] flutes Smallest Largest 1 2 3 4 5 6 0,20 9 0,58 0,375 0,20 0,75 1,26 6 8,52 12 11,51 5,75 3,83 2,87 2,30 8 0,27 12 0,77 0,500 0,27 1,00 1,68 6 11,36 16 15,34 7,67 5,11 3,83 3,06 10 0,33 15 0,96 0,625 0,33 1,25 2,10 6 14,2 20 19,18 9,58 6,39 4,79 3,83 12 0,40 18 1,15 0,750 0,40 1,50 2,52 6 17,04 24 23,01 11,50 7,66 5,74 4,59 16 0,54 24 1,54 1,000 0,54 2,00 3,36 6 22,72 32 30,68 15,34 10,22 7,66 6,12 20 0,67 30 1,92 1,250 0,67 2,50 4,20 6 28,4 40 38,35 19,17 12,77 9,57 7,65 Recommended Feed 100% 70% 50% 30% 10% widia.com O153
