1.11.2 Calling machining cycles (turning)
Functionality
Cycle are technology subroutines that realize a certain machining process, Adaptation to the
particular problem is performaed directly via supply parameters/values when calling the
respective cycle.
Programming example
N10 DEF REAL RTP, RFP, SDIS, DP,
DTB
N20 G18 X100 Z100
N30 M3 S100 F0.1
N40 G17 X0
N50 CYCLE83(110, 90, 0, -80, 0,
-10, 0, 0, 0, 0, 1, 0)
;Call of cycle 83, transfer values directly,
separate block
N60 G0 X100 Z100
N70 RTP=100 RFP= 95.5 SDIS=2.4,
DP=-20, DTB=3
;Set transfer parameters for cycle 82
N80 CYCLE82(RTP, RFP,SDIS, DP, ,
DTB)
;Call of cycle 82, separate block
N90 M30
1.11.3 Executing external subroutines (EXTCALL)
Function
With the EXTCALL command, you can reload and execute programs stored on an external
USB memory sticker.
Machine data
The following machine data is used for the EXTCALL command:
● MD10132 $MN_MMC_CMD_TIMEOUT
Monitoring time for the command in part program
● MD18362 $MN_MM_EXT_PROG_NUM
Number of program levels that can be processed simultaneously from external
● SD42700 $SC_EXT_PROGRAM_PATH
Program path for external subroutine call
NOTICE
When using SD42700 $SC_EXT_PROGRAM_PATH, all subprograms called with
EXCALL are searched under this path.
