GENERAL TECHNICAL INFORMATION CHIP GULLET AND FRONT FLUTE DESIGN The number of flutes depends on: P workpiece material. P size of workpiece. P milling conditions and profile shape. Cutters with higher number of flutes have to be preferred, as long as chip flow is guaranteed. Geometry of front flutes A = 2 flutes, 2 flutes cutting to center. B = 2 flutes, 1 flute cutting above center. C = 3 flutes, 1 flute cutting above center. D = 4 flutes, 2 flutes cutting to center. E = 2 or 4 flutes, not cutting above center. F = 5 or 6 flutes, not cutting above center. Geometry of front edges PA = Axial primary relief angle SA = Axial secondary clearance angle Ra = Radial rake angle aA = Axial rake angle tA = Dish angle d1 = Cutter diameter a = Helix angle 460
