where the slots have to be rotationally in order to position them for a balanced
stock removal amount on both flank types (lower and upper flanks).

Figure 42: Orienting the upper flank

In the case of Uniflex pinion stock division the upper and lower positions are
reversed compared to the gear stock division. Uniflex pinion part programs
process the upper flanks first and then process the lower flanks.

30.10 Machining Process and Cutting Results

The Uniflex swing motion is demonstrated in Figure 43 by the example of cut-
®
ting with a 15” Coniflex Plus cutter. In the left photo in Figure 43 the cutter is
positioned at the heel position. It is then moved in the direction of the toe and
reaches in the center photo, the mean face position and is close to the toe in
the right-side photo of Figure 43.

Cutting results from machining a Coniflex ring gear with a face width of 105mm
using a cutter with 15” diameter are shown in Figure 44. The result from a
standard Coniflex cutting process is shown in the left photo. Hourglass shaped
root fillets in face width direction as well as the fins in the center of the root are
evident. The right-side photo in Figure 44 was made from the same ring gear
design but it was manufactured with Uniflex. The root fillets look nearly parallel
along the face width and are smooth without any fins.
