Programming technology functions (cycles)
General
General geometry parameters
● Retraction plane RP and reference point Z0
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.
Note
If the values for reference point and retraction planes are identical, a relative depth
specification is not permitted. Error message "Reference plane defined incorrectly" is
output and the cycle is no
t executed.
This error message is also output if the retraction plane is located after the reference
point, i.e. its distance to the final drilling depth is smaller.
● Safety clearance SC
Acts in relation to the reference point. The direction in which the safety clearance is active
is automatically determined by the cycle.
● Drilling depth
Depending on the selection of the drill shank or drill tip or the centering diameter, the
programmed drilling depth refers to the following for cycles with a selection field:
– Tip (drilling depth in relation to the tip)
The drill is inserted into the workpiece until the drill tip reaches the value programmed
for Z1.
– Shank (drilling depth in relation to the shank)
The drill is inserted into the workpiece until the drill shank reaches the value
programmed for Z1. The angle entered in the tool list is taken into account.
– Diameter (centering in relation to the diameter, only for CYCLE81)
The diameter of the centering hole is programmed at Z1. In this case, the tip angle of
the tool must be specified in the tool list. The drill is inserted into the workpiece until
the specified diameter is reached.
The cycle assumes the tested hole coordinates of the plane.
