Using GLOBAL DEF information
If you have entered the corresponding GLOBAL DEF functions at the
beginning of the program, then you can link to these globally valid
values when defining any machining cycle.
Proceed as follows:
Select the Programming and Editing operating mode.
Select the machining cycles.
Select the desired group of cycles, for example:
drilling cycles.
Select the desired cycle, e.g. DRILLING.
The TNC displays the SET STANDARD VALUES soft
key, if there is a global parameter for it.
Press the SET STANDARD VALUES soft key. The TNC
enters the word PREDEF (predefined) in the cycle
definition. You have now created a link to the
corresponding GLOBAL DEF parameter that you defined
at the beginning of the program.
Please note that later changes to the program settings
affect the entire machining program, and can therefore
change the machining procedure significantly.
If you enter a fixed value in a machining cycle, then this
value will not be changed by the GLOBAL DEF functions.
