Please Note While Programming; Cycle Parameters - HEIDENHAIN TNC 620 User Manual

Fixed Cycles: Contour Pocket | PILOT DRILLING (Cycle 21, DIN/ISO: G121, software option 19)

Please note while programming:

When calculating the infeed points, the TNC does not
account for the delta value DR programmed in a TOOL
CALL block.
In narrow areas, the TNC may not be able to carry out
pilot drilling with a tool that is larger than the rough-out
tool.
If Q13=0, the TNC uses the data of the tool that is
currently in the spindle.
After the end of the cycle, do not position the
tool in the plane incrementally, but rather to an
absolute position if you have set the ConfigDatum
> CfgGeoCycle > posAfterContPocket parameter to
ToolAxClearanceHeight.

Cycle parameters

Q10 Plunging depth? (incremental): Dimension
by which the tool drills in each infeed (minus
sign for negative working direction). Input range
-99999.9999 to 99999.9999
Q11 Feed rate for plunging?: Traversing speed of
the tool in mm/min while plunging. Input range 0
to 99999.9999, alternatively FAUTO, fu, FZ
Q13 Rough-out tool number/name? or QS13:
Number or name of rough-out tool. You are able
to apply the tool via soft key directly from the tool
table.
