8.2

Calling cycles for tool change

You can call a user cycle with "M" or "T" code to perform the tool change operations.
Note
An "M" code and a "T" code for calling user cycles must not be in the same program block.
The following examples are given for the tool change on a milling machine.
Calling a tool change cycle with "M6"
Configure the parameters shown in the table below to activate an M code for calling a standard cycle:
Parameter Name
22550 TOOL_CHANGE_MODE
22560 TOOL_CHANGE_M_CODE
10715 M_NO_FCT_CYCLE[0]
10716 M_NO_FCT_CYCLE_NAME[0]
For the format of a standard cycle, refer to the example below:
%_N_TOOL_SPF
;$PATH=/_N_MPF_DIR
PROC TOOL SAVE DISPLOF
IF $P_ISTEST GOTOF _END
IF $P_SEARCH<>0 GOTOF _END
IF $P_TOOLNO==$P_TOOLP GOTOF _NO
G500 D0
G75 Z=0
SPOS=$MN_USER_DATA_FLOAT[0]
MSG("Ready to change tool *** Original tool num-
ber: T"<<$P_TOOLNO)
;>>> User-defined M codes can be used to start the PLC logic for tool change after spindle position-
ing
;>>> PLC sets signal "Read-in disable" (DB3200.DBX6.1) to stop this standard cycle
;>>> PLC controls the action of tool magazine and turret
;>>> After the tool change, PLC resets signal "Read-in disable" to resume the cycle
