MCALL Modal subprogram or cycle call
Siemens 840D 828D G-code · Mill and lathe
Calls a cycle or subprogram again after every following block with an axis move. Used to drill or machine the same feature at many positions. MCALL alone cancels it.
Format
MCALL CYCLE81(...) or MCALL NAME
Addresses
| Address | What it does |
|---|---|
CYCLE or NAME | Cycle or subprogram called at every position |
How it works
Modal until MCALL alone or a new MCALL.
Example program
MCALL CYCLE81(50,0,2,-10,) ; DRILL AT EACH POSITION
X20 Y20 ; HOLE 1
X40 Y20 ; HOLE 2
X60 Y20 ; HOLE 3
…
X20 Y20 ; HOLE 1
X40 Y20 ; HOLE 2
X60 Y20 ; HOLE 3
…
The full 5-line example is in the app. Example is in inch. Check offsets and clearances first.
Watch out for
- Only one modal call can be active. A new MCALL replaces the old one.
- Cancel with MCALL before moving to the tool change position, or the cycle runs there too.
