Hello.
Sorry for the dumb question but I am new to this.

I was wondering if someone could tell me how to program a peck drilling cycle without x and y position.

What I need to do is drill a buch of holes in random positions to a specific depth. I could do this by hand but I think it would be best with a cnc. What I would like it to do is for me to jog it to a position that the hole should be in run a program and have it drill .5 inches down clearing the chips with the machine using the tool offset as to how deep the hole needs to be and where the top of the part is. What I do not want it to do is go to a specific x and y position, it should just stay put and go down to a proper depth.

The machine is a Haas sr 100 gantry.


Thank you so much.

Use G91 with X0. Y0.

You need to turn SETTING 28 CAN CYCL ACT W/O X/Y ON.

Now the G83 peck cycle will work without having any X and Y in the command line.

Now enter the tool offset and write a short program in MDI. All you need is the spindle start, a Z move down to your start plane, the G83 line and then a retract to a safe height. Something like this:

M03 S2000
G00 Z1.
G83 Z-0.5 Q0.2 F10. R0.1 L1
G53 G00 Z0.
M30

Handle jog to your chosen position, push MDI and cycle start then back to Jog for the next position.
