Multi-Edge (Cycle79) - Siemens SINUMERIK 840D Operating Manual

Parameter Description
The positions refer to the reference point:
X0 Reference point X – (for single position only)
Y0 Reference point Y – (for single position only)
Z0 Reference point Z – (for single position only)
∅ Diameter of spigot
L Length of spigot
R Corner radius
α0 Angle of rotation
Z1 Spigot depth (abs) or depth relative to Z0 (inc) - (only for ∇ and ∇∇∇)
DZ Maximum depth infeed - (only for ∇ and ∇∇∇)
UXY Plane finishing allowance for the length (L) and width (W) of the circular spigot.
Smaller circular spigot dimensions are obtained by calling the cycle again and
programming it with a lower finishing allowance. - (only for ∇ and ∇∇∇)
UZ Depth finishing allowance (tool axis) - (only for ∇ and ∇∇∇)
∅1 Diameter of blank spigot (important for determining approach position) - (only for ∇ and
∇∇∇)
FS Chamfer width for chamfering - (for chamfering only)
ZFS Insertion depth of tool tip (abs or inc) - (for chamfering only)

Multi-edge (CYCLE79)

Function
You can mill a multi-edge with any number of edges with the "Multi-edge" cycle.
You can select from the following shapes with or without a corner radius or chamfer:
Approach/retraction
1. The tool approaches the starting point at rapid traverse at the height of the retraction
2. The tool traverses the multi-edge in a quadrant at machining feedrate. The tool first
3. When the first plane has been machined, the tool retracts from the contour in a quadrant

plane and is fed in to the safety clearance.
executes infeed at machining depth and then moves in the plane. The multi-edge is
machined depending on the programmed machining direction (up-cut/down-cut) in a
clockwise or counterclockwise direction.
and then infeed to the next machining depth is performed.
