Calling Machining Cycles (Turning); Executing External Subroutines (Extcall) - Siemens sinumerik 808d Programming And Operating Manual

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)
N60 G0 X100 Z100
N70 RTP=100 RFP= 95.5 SDIS=2.4,
DP=-20, DTB=3

NOTICE
When using SD42700 $SC_EXT_PROGRAM_PATH, all subprograms called with
EXCALL are searched under this path.
