Automatic Alignment Cycle

[sullivnc]

Hi all,

I have a rather unique problem that I'm trying to solve. I guess first, let me describe my process. We use Haas VF2's with diamond core drills to core out all different types of glass. We scribe our parts on the glass first, along with crosshairs at (4.625, 0) and (-4.625, 0). I have cameras mounted on the spindles with a live feed going out to monitors on top of the machines, which run through a digital crosshair generator to produce a crosshair in the center of the screen. My operators, after mounting the work to the table, turn on the monitors and line up the righthand laser engraved crosshair with the digital crosshair. Then, they hand jog over to the lefthand crosshair. After manually fixing any rotation error (the work is mounted on manual rotary tables), they jog back to the righthand crosshair to make sure that both crosshairs are perfectly aligned on the X-axis. Then, they have to copy down the locations of the crosshairs, do some math, and enter the center of the plate as their G55 offset.

I know how I can do the math and set the G55 offset programmatically using macros. I'm trying to semi-automate the rest of the process. I can jog them to the approximate righthand crosshair position. So here are my questions:

1) Is there a way I can pause, but not stop, the program and allow them to hand jog with the program paused at a certain line?
2) This one I'm almost certain isn't possible, but I might as well ask. My dream is that they would be able to run a subroutine once they are directly above a crosshair, and I could automatically gather the machine position and pass that to a variable (or multiple variables, one each for X and Y). Has anyone ever tried anything like this? Thanks for any input.

Does the scribing and stuff with the rotary relate to some optic centerline buisness? Or just material nesting/ usage?

1 Pausing wont help in my experience on a Hass because. For me at least. Going from memory to Jog rewinds the program. Maybe its a parameter.

1) You can't jog, and have the program pick back up. You can do RUN STOP JOG CONTINUE, but I believe that will return to the previous position. You could get tricky with macros, and create a program that runs different sections each time you press cycle start. That is, for the first run, you would set #100= 1, and use logic to run the first section. Then, the second time you run, the program sees that #100=1, and jumps to section 2, etc, and then the final section has to reset #100= 0. All this depends on the operators not trying to restart the program, return to a previous step, or whatever.

2) There are macro values for current machine and work offset positions, so yes, you can save those to global macros. Just remember to block lookahead before you want to save them, so you don't get the wrong values. Look in the manual for the addresses.

Hey guys,

I've been trying to get this done forever, and was finally able to get a program working! I cut our alignment time from over 5 minutes to just over 1 minute. I just wanted to share it and ask a few questions. The first M109 is really the only place I need operator input, the other ones are just to display a message. Is there a way to display a message without requiring user input? I'd rather it just continue to the next line, which is an M00, and display the instructions for what to do while the program is stopped. Actually, I guess that's my only questions. Let me know what you think, I'm always open to suggested improvements.

UPDATE: Realized the M00 would overwrite my message anyways. Settled on training my operators to press WRITE/ENTER, which keeps the variable set at 0.
