Supplementary conditions
The following supplementary conditions
must be observed for an active T function replacement
(default setting for turning):
● The cycle defined in MD10717 $MN_T_NO_FCT_CYCLE_NAME and executed with the T
call, is not started with the TCA command.
To ensure that a tool change cycle can also be started when TCA is programmed, the
language command TCA must be redefined in _TCA (default setting NC).
● TCA can be substituted with a replacement cycle. The name of the replacement cycle is
entered in MD15710 $MN_TCA_CYCLE_NAME. This replacement cycle is called from the
cycle of the redefined TCA function (TCA.SPF from the toolbox).
● The T and TCA replacement can be implemented in a common replacement cycle.
There is a sample cycle in the toolbox for the replacement of both tool calls in a common
replacement cycle.
Note
The offset selection, in
accordance with MD20270 $MC_CUTTING_EDGE_DEFAULT, acts in
the same way as for the T command. TCA and D must not be programmed in the same block.
The following example describes the sequence:
PROC TCA(STRING[64] _TOOL_NAME,INT _DUPLO,INT _TH_NO)
;VERSION: 01.00.07. Oct 22, 2009
;CHANGE: 01.00.07. Oct 22, 2009
TCA(_TOOL_NAME,_DUPLO,_TH_NO) ;Tool call to NC
; here, insert the machine functions for the change
M17
References
The function is available irrespective of tool management and is described in full in:
Function Manual, Basic Functions
(K1) in Section "Replacement of functions by subprograms"
9.7.4 Example: Block search and MCALL
Requirement
In the tool change subprogram, you must ensure for the block search via modally called cycles
(e.g. drilling cycles) that the modal call is retained and ensure that the correct tool is used.
After a block search with calculation, the tool change subprogram (L6) is called in the block
search ASUB. The modal call may only be deselected there when L6 has not been called from
the ASUB.
