21.3 Manufacturer cycles

T replacement cycle

If a T replacement cycle is being used, then the following note must be observed:

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.

CUST_TECHCYC.SPF manufacturer cycle

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
