Description
∇ (roughing)
•
∇∇∇ (finishing)
•
∇ + ∇∇∇ (roughing and finishing)
•
Groove position:
Reference point in X ∅
Reference point in Z
Groove width
Groove depth ∅ (abs) or groove depth referred to X0 or Z0 (inc)
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.
Finishing allowance in X or finishing allowance in X and Z – (only for ∇ and ∇ +
∇∇∇)
Finishing allowance in Z – (for UX, only for ∇ and ∇ + ∇∇∇)
Number of grooves (N = 1....65535)
Distance between grooves (inc)
DP is not displayed when N = 1
