Calling a cycle in connection with point tables

If you want the TNC to call the last defined fixed cycle at the points
defined in a point table, then program the cycle call with CYCLE CALL
PAT

:

8

To program the cycle call, press the CYCL CALL key.

8

Press the CYCL CALL PAT soft key to call a point

table.

8

Enter the feed rate at which the TNC is to move from

point to point (if you make no entry the TNC will move
at the last programmed feed rate; FMAX not valid).

8

If required, enter a miscellaneous function M, then

confirm with the END key.

The TNC moves the tool back to the clearance height over each
successive starting point (clearance height = the spindle axis
coordinate for cycle call). To use this procedure for cycles above Cycle
199, you must define the 2nd set-up clearance (Q204) to equal 0.

If you want to move at reduced feed rate when pre-positioning in the
spindle axis, use the miscellaneous function M103 (see “Feed rate
factor for plunging movements: M103” on page 248).

With CYCL CALL PAT the TNC runs the point table that you
last defined (even if you defined the point table in a
program that was nested with CALL PGM).
