T replacement cycle
If a T replacement cycle is being used, then the following note must be observed:
Note
The CUST_T cycle uses the language command TCA (ToolChangeAbsolut) for the T call and
therefore also has the possibility of inserting tools that have been disabled. However, this
language command cannot be substituted.
The following must be observed if working at a machine with T replacement:
● The T preparation cycle must be explicitly called at the specified position.
● If the call is realized using the CUST_T cycle, then the parameter evaluation
($C_TS_PROG, …) is skipped.
Alternatively, the original TCA language command can be reprogrammed.

21.3.5 CUST_TECHCYC.SPF manufacturer cycle
Function
For technological cycles, the CUST_TECHCYC cycle is called from ShopMill and ShopTurn
cycles, if the machine builder must make certain adaptations to a specific machine (e.g.
activate specific M commands). For instance, this may be necessary in order to retract or
extend part catchers when cutting off parts on lathes or to position a spindle for clamping (only
in JobShop).
The CUST_TECHCYC.SPF cycle can be used to program and execute the necessary
sequences.
