retract distance error

[cristian anabalon]

im using a q01x40 tip for .090 slot but i mesure the part retract and hits the other wall like a pin ball pcdmis3.7 please help.
i have my retract distance to .001 but givs me a error too.

Your hole (no joke intended) is probably too far off nominal location. Depending the on the size of the hole, Pcdmis will internally change the pre-hit and retract values for holes with a radius smaller than the prehit/retract values set in the program. Have you tried using READ POS for the hole? This will prompt you to put the tip in the center of the hole and it will then measure the hole using that as the target location (but keeps the same nominals). As for the retract, set it back up to what ever you are using for the rest of the program.

I think he is measuring a slot Matt.

Does not matter, works the same for any type of hole (circle, round slot, square slot).

[Paul Barriage]

Is this an auto-slot? or manually learned? Manually learned may have a tendency to not get the slot rotation correct.

Otherwise, as Matt said, it may be off position enough to cause problems. If it is moving around too much, you may need to add 'find hole'.

[rebeldude]

Also, check your "manual" retract. If it is set too high, it can give you that error also

[Peter Warcholyk]

If you're having difficulties "finding" the slot, you might want to try the "find hole" function as well.
This is a function that I utilize quite often, with good success.

His problem is the backoff after the touch is causing the tip to hit the other side which is where he is getting this "pinball" effect.

I dont think PCDMIS allows you to control the backoff at the controller level on the Sheffield. (not sure)

You may have to call Sheffield Tech support ask them "When you adjust the retract does that also adjust the Controller's backoff".

Try knocking your move speeds down to 5mm/s right before this feature(not the touch speeds)

I don't know about a sheffeild. On the Wenzil I run, manual retract controls that

I assumed he was not using an autofeature. You are assuming he is using an autofeature. He didn't say which is he doing.

Sheffield has a "built in" retract that is independant of the retract set in the .prg. As soon as a hit is taken (even in manual mode) the machine vectors away from the surface.

AH, but he IS measuring a slot, and the only way to do that IS with an AUTO FEATURE!

There, I have run circles around you logically, now go 'way or I shall taunt you a second time!

That all depends on what he is trying to do with this slot. Could be that he has a location called out from one side of the slot. Then all he would need is the location of one side of the slot measured as a line.

Oh, and I wouldn't brag about running circles around me logically, a blind retarded chimp could do that with one hand tied behind its back.
