Parameters Description Unit
α1, α2 Flank angle 1 or flank angle 2 - (only for grooves 2 and 3)
Asymmetric grooves can be described by separate angles. The angles can be
between 0 and < 90°.
Degrees
FS1...FS4 or R1...R4
Chamfer width (FS1...FS4) or rounding radius (R1...R4) - (only for grooves 2 and
3)
mm
D
Maximum depth infeed for insertion – (only for ∇ and ∇ + ∇∇∇)
For zero: Insertion in a cut – (only for ∇ and ∇ + ∇∇∇)
D = 0: 1. cut is made directly to final depth T1
D > 0: 1st and 2nd cuts are made alternately to infeed depth D, in order to achieve
a better chip flow and prevent the tool from breaking, refer to
approaching/retraction when roughing.
Alternate cutting is not possible if the tool can only reach the groove base at one
position.
mm
UX or U Finishing allowance in X or finishing allowance in X and Z – (only for ∇ and ∇ +
∇∇∇)
mm
UZ Finishing allowance in Z – (for UX, only for ∇ and ∇ + ∇∇∇) mm
N Number of grooves (N = 1....65535)
DP Distance between grooves (inc)
DP is not displayed when N = 1

8.4.4 Undercut form E and F (CYCLE940)
Function
You can use the "Undercut form E" or "Undercut form F" cycle to turn form E or F undercuts
in accordance with DIN 509.
Approach/retraction
1. The tool first moves to the starting point calculated internally in the cycle at rapid traverse.
2. The undercut is made in one cut at the machining feedrate, starting from the flank
through to the cross-feed VX.
3. The tool moves back to the starting point at rapid traverse.
Procedure
1. The part program to be executed has been created and you are in the
editor.
2. Press the "Turning" softkey.
