Please Note While Programming - HEIDENHAIN TNC 620 User Manual

Fixed Cycles: Drilling | UNIVERSAL PECKING (Cycle 205, DIN/ISO: G205, software option 19)

Please note while programming:

Program a positioning block for the starting point (hole
center) in the working plane with radius compensation
R0.
The algebraic sign for the cycle parameter DEPTH
determines the working direction. If you program
DEPTH=0, the cycle will not be executed.
If you enter different advance stop distances for Q258
and Q259, the TNC will change the advance stop
distances between the first and last plunging depths at
the same rate.
If you use Q379 to enter a deepened starting point,
the TNC merely changes the starting point of the
infeed movement. The TNC does not change retracting
movements; the are referenced to the coordinate of the
workpiece surface.
Danger of collision!
If you enter a positive depth with a cycle, the TNC reverses
calculation of the pre-positioning. This means that the tool
moves at rapid traverse in the tool axis to set-up clearance
below the workpiece surface!
Enter depth as negative
Enter in machine parameter displayDepthErr (No. 201003)
whether the TNC should output an error message (on) or not
(off) if a positive depth is entered
