Feed Direction
Down (climb) milling is recommended. Up milling or plunging are possible. (In down milling or plunging, backlash should be eliminated.) Defining Actual Feed Chip thickness decreases as the depth of cut decreases. Therefore, recommended feed (f ) z can be increased as shown in the table.

overlap of radii. When a projection is allowed at the bottom of the groove, ∆S1 and ∆S2 may be increased theoretically up to the corner size of the insert. ∆A max - Maximum possible side ground for each cutter 5 Pins of the driving flange set should be lengthened ∆S max - Maximum possible shim width for each cutter to ensure contact length of at least 8 mm into W, W1, W2 - Normal width of insert one flange and 3 mm into the other. 6 When coupling cutters W=6.35, a shim (S) Milling Wider Slots with of 0.16 mm minimum thickness must be used. Stacked, Double Cutters 7 The tolerance of effective widths is up to ± 0.2 mm. Due to the accumulation of tolerances, a step of 0.1 mm may occur at the groove bottom.
