Please Note While Programming; Cycle Parameters - HEIDENHAIN TNC 320 User's Manual For Cycle Programming

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 during 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.
