Retraction plane (abs)
Normally, reference point Z0 and retraction plane RP have different values. The
cycle assumes that the retraction plane is in front of the reference point.
Safety clearance (inc)
Acts in relation to the reference point. The direction in which the safety clearance
is active is automatically determined by the cycle.
Feedrate
∇ (roughing)
•
∇∇∇ (finishing)
•
∇∇∇ edge (edge finishing)
•
Chamfering
•
Single position
•
A circular spigot is machined at the programmed position (X0, Y0, Z0).
Position pattern
•
Several circular spigots are machined in a position pattern (e.g. pitch circle,
grid, line).
The positions refer to the reference point:
Reference point X
Reference point Y
Reference point Z
Diameter of blank spigot
Number of edges
Width across flats or edge length
Angle of rotation
Rounding radius or chamfer width
Multi-edge depth (abs) or depth in relation to Z0 (inc) - (only for ∇, ∇∇∇ and ∇∇∇
edge)
Chamfer width for chamfering - (for chamfering only)
Insertion depth of tool tip (abs or inc) - (for chamfering only)
Maximum plane infeed - (only for ∇ and ∇∇∇)
Maximum depth infeed - (only for ∇ and ∇∇∇)
Plane finishing allowance - (only for ∇, ∇∇∇ and ∇∇∇ edge)
Depth finishing allowance – (only for ∇ and ∇∇∇)
