Example: When using ae (max), Then ap = ad max mm2 / ae max When using ap max, then ae = ad max mm2 / ap max = 15.5 / 1 = 15.50 / 32.50 hm = 15.50mm = 0.47mm Example based on values for RSM250 (Z=10) hm Key: ap ap ae Radial depth of cut (mm) fz ae ap Axial depth of cut (mm) ae ad Cutting section (mm2) fz fz Feed per tooth (mm/z) hm Effective chip thickness (mm) Cutting Section (ad) and Speed (Vc) Correction Coefficients When the length to diameter (Lu:D) exceeds 3:1 the cutting When the length to diameter (Lu:D) exceeds 3:1 the speed section (ad) should be reduced as per the following graph. (Vc) should be reduced as per the following graph.
