Wire EDM outside radius datum pickup attachment?

[EDM Ed]

implmex, totally going to get a ball ended stylus, i just didnt bother drawing it. ​

​

I will figure out the probe offset by cutting a hole in scrap, probe it several times with the stylus including removing and reinstalling to see if it even works right.​

Then I will use that offset information to write some custom gcode macros to probe features with in programs.​

​

I already created a custom wire alignment program to align using a hole in a fixture on the table, instead of the manual block alignment system sodick uses.​

So this should be similar.​

Hello,

New to EDM and Machining in general, we have Mitsubishis at our shop and I've been trying to dig around the concept of adding a probe if possible for all the same reasons everyone else has mentioned. I'm curious though as to how the probe will actual work when you have it on the machine. The machine can probe with wire but, to my knowledge, only when it reaches material that it makes conductive contact with. With a probe, how will the machine know when its made contact?

The machine has to be put in a 'feed per min' mode ( ignores spark generator feedback ).
Then the high-speed skip signal is used for the probing. ( may require control options ).

So in my little test I did with a few magnets and an ejector pin, I just had the pin conductively connected to the upper head. When it touched it completed the circuit as if the wire was what was grounding to the table thru the part. The probe I designed and we have built should do the same thing, I have not had a free moment on the machine to start my testing yet, too many parts to make for customers.

You should check with Mitsubishi about probing, many of the newer Wire EDMs have have options for external Renishaw style probes. I know that the new Sodick WireEDMs have the ability to have a Renishaw probe installed.

That's kind of how I assumed it would work, as long as it's mounted on a conductive area of the upper head. I know when I've accidentally run the head into things when edge finding it will stop due to contact.

For the Mits wire I would just grab the probing program from the sinkers. Its right there in the prg list to edit, etc
Wouldn't take much to repurpose it for a wire edm.

I don't run Mits machines, and I am sure they can probe with the wire just like the Sodicks I do run. The fixture I am creating is to probe datum features of parts that the wire cannot get too, like a boss in the middle of a flange, etc.

 

[SteveEx30]

Yes I understand. I was referring to the guy who said he had a Mits wire. If his machine doesn't have a probing cycle, be easy to take one from a Sinker.

Do Sodick wires have a built-in probing cycle for you to run with your probing setup your making?

 

[nlancaster]

Yes, they have built in probing with the wire, so I am just going to use that short to ground probing with my external probe.

Sadly these AG600Ls don't have an option for external probing, the newer Sodicks apparently do have the ability for an external renishaw probe.
