30.2 The Uniflex Principle
Similar to the Unimill principle of spiral bevel gear cutting with a flared cutter as
shown in Figure 1, in Uniflex a flared tool follows the much larger peripheral
contour of a virtual cutter or grinding wheel. The principle is graphically ex-
plained in Figure 2. In the example in Figure 2, a design cutter with 2000mm
radius was used in order to achieve a straight root line and/or to avoid hour-
glass shaped root fillets and mutilations of the opposite flanks. The cutter or
grinding wheel used in Uniflex has a 190mm radius which corresponds to a 15”
tool diameter.
