Can someone please just write a short example of a drilling cycle, on a fanuc control, with a right angle head.If I'm drilling in the "y" direction.
I tried this and it didn't work.

Here is one fresh from the machine. Drilling, chamfering, then tapping in the X minus direction.

.
never, never use G17 with horizontal head pointing at X or Y
.
drill will drill sideways
.
i have hit reset and G17 is one of default settings then drill basically tried to slot a hole as it went side ways.
.
got to watch reset and defaults that come in effect with the reset

Thank you.

Your G19 should be a G18. G18 would put you in the X/Z plane, meaning that Y is the drilling axis.

I would also avoid any X/Z values on the G83 line. It will only confuse you, and possibly even the control. And watch that R-plane value... Remember that it's absolute...

Try this instead... (Basically your code, cleaned up...)

On one FAnuc machine I worked on (15 yrs ago) there was a parameter "Z drilling axis only" or some such that kept g83 from working in other planes. Turned it off and G83 worked in any of G17, 18 or 19 planes. It also allowed for tool length offset in any plane.
