Description
Reference tool Tool, which is used in the "stock removal" machining step. This is
used to determine the plunge position.
Face C
•
End face Y (only when Y axis exists)
•
Face B
•
Peripheral surface C
•
Peripheral surface Y (only when Y axis exists)
•
Clamp/release spindle (only for end face Y/B and peripheral surface Y)
The function must be set up by the machine manufacturer.
Reference point in the tool axis Z
Pocket depth ∅ (abs) or depth referred to Z0
Positioning angle for machining area
- (only for ShopTurn, machining surface, face Y)
Positioning angle for machining surface
- (only for ShopTurn, machining surface, peripheral surface Y)
Maximum plane infeed
•
Maximum plane infeed as a percentage of the milling cutter diameter
•
Finishing allowance, plane
Lift mode before new infeed
If the machining operation requires several points of insertion, the retraction
height can be programmed:
To retraction plane
•
Z0 + safety clearance
•
When making the transition to the next insertion point, the tool returns to this
height. If there are no elements larger than Z0 in the pocket area, Z0 + safety
clearance" can be selected as the lift mode.
