Tool edge radius is also required in order to calculate the error compensation
of the cutter reference height measurement shown in Figure 36.

The tool inclination angle is also called the flare angle. The blade slots in a
®
Coniflex Plus cutter are inclined by 18°. The flare angle is defined as 90°-18°
= 72°. The summary input value therefore is 72° in all cases of Uniflex cutting
and grinding.

Tool Included angles are measured over both sides, the pressure angle side
and the clearance side. A cutter head built according to the summary in Figure
16 has an included tool angle of 36°.

The tool RPM is calculated with V = 250m/min for cutting and V = 24m/s for
grinding to achieve the ideal cutting surface speed:

RPM = 1000▪V[m/min]/(D[mm]▪p ) [1/min] … Cutting
RPM = 60[s/min]▪1000▪V[m/min]/(D[mm]▪p ) [1/s] … Grinding

The start roll rate is the beginning speed of the generating roll in °/sec. Ade-
quate values can be found in Tables 1, 2 & 3 or in the Coniflex cutting or
grinding summary of the particular job.

The end roll rate is the roll rate at the end of the generating roll in the root.
Adequate values can be found in Tables 1, 2 & 3 or in the Coniflex cutting or
grinding summary of the particular job.

Uniflex performs slow, moderate and rapid moves. The machine uses the slow
move feed rate if cutting contact still exists (500mm/min is recommended).

Moderate move feed rate is used for short distances between two cutting
contacts (1000mm/min is recommended).

The rapid move feed rate is used to bridge long distances when no cutting
contact can occur. The recommended default is 5000mm/min.

Plunge feed rates are used for the Uniflex specific heel plunge without swing.
Instead of end chip amounts, the heel plunge requires a plunge feedrate which
ramps down as the blades are more engaged in the slot.

First plunge feed rate (see Tables 1, 2 &3).

Second plunge feed rate (see Tables 1, 2 & 3).
