CNC Machinist Calculator UltraG65 Macro call / Custom macro call
Fanuc G-code · Mill, Lathe
On mills: Macro call
Calls a macro program once and passes values to it through letter addresses. The letters become local variables such as A to #1 and B to #2.
Format
G65 P [L] [A B C ...]
Addresses
| Address | What it does |
|---|---|
P | Program number of the macro |
L | Number of repeats, 1 if left out |
A to Z | Arguments passed as local variables |
How it works
One shot, group 00.
Example program
G90 G54 G00 X0. Y0. (CIRCLE CENTER)
G43 H01 Z1. (LENGTH COMP)
G65 P9010 R1.5 Z-.5 H6. (BOLT CIRCLE MACRO, 6 HOLES)
G00 Z1. (CLEAR)
G43 H01 Z1. (LENGTH COMP)
G65 P9010 R1.5 Z-.5 H6. (BOLT CIRCLE MACRO, 6 HOLES)
G00 Z1. (CLEAR)
Example is in inch. Check offsets and clearances first.
Watch out for
- G, L, N, O and P cannot be used as arguments.
- Arguments with a decimal point are passed as written. Without one, the value may be read in least input units.
- Probe cycles from builders are usually G65 calls. Check the arguments in their manual.
On lathes: Custom macro call
Calls a macro program once and passes values through letter arguments, which arrive as local variables such as A in #1 and B in #2.
Format
G65 P [L] arguments
Addresses
| Address | What it does |
|---|---|
P | Program number of the macro |
L | Number of times to repeat, 1 if left out |
A B C and others | Arguments passed to local variables |
How it works
Non-modal. G66 is the modal version.
Example program
G00 X2.1 Z-.5 (POSITION)
G65 P9010 A1.5 B.25 (CALL GROOVE MACRO, DIA 1.5, WIDTH .25)
G00 X3. (CLEAR)
G65 P9010 A1.5 B.25 (CALL GROOVE MACRO, DIA 1.5, WIDTH .25)
G00 X3. (CLEAR)
Example is in inch. Check offsets and clearances first.
Watch out for
- Use decimal points in arguments. A1 can be read as A.0001 in inch.
- Letters G, L, N, O and P cannot be used as arguments.
