Thread: A axis programming question

I'm having a brain fart right now. I'm trying to write the shortest possible code to drill 36 holes around the o.d. of a part. I don't want to have to write it like:

g81 z-.o6 r.05 f20.
a20.
a30.
..........
a350.
g0 g80 z.1

I'm sure there is a shorter way to write the code but I can't remember how to write it.

Thanks!

Does L35 tell it to go back to the top line 35 times?

pretty much, g91 a10. means incrementally (10 degrees) and the L (loop) every 10 degrees 35 times .

Ya, "L" tells it to repeat the move 35 times. And, G91 throws it into incremental mode so that each movement is A10.
