double lock vises

[Joels]

Hello, I need to program 4 parts on one vise. The vise is a double lock KURT. So i have the center portion which does not move and the outer jaws that do move. I nee to program the parts 1-8 names E1-E8. what is the best way to locate the home position on E3,E4,E7 and E8? I would like to keep them the same place if possible.

Joel,

 

Need more info. You state 4 parts but then decribe needing more than 4 names.

 

Are the parts all the same? Are they all the same OP?

 

I don't understand your question clear enough to provide help.

[Joels]

there will be 4 parts in each vice so i was going to give each parts a E fixture offset for a Fadal VMC. The parts will be the same as i am going to machine one operation at a time so all 4 parts will have the same operation. the second vice will be setup the same way but E fixtures 5 thru 8. I am looking for the best way to give all 4 parts on the first vice a E # or fixture offset.

Joel,

 

I am still a little unclear what you are looking to do.

 

If I understand correct, each part should have it's own workoffset, in your case E#. Not knowing if you will be holding these parts in soft jaws or hard jaws it's a bit hard to make a good recommendation. More than likley the origins of 2 all parts will be different and that's not a great situation unless you are profiling around the stock. If you are, the first OP will be fine but the second may not depending on the part tolerances.

 

Do you have experience with transform toolpaths and the workoffsets indexing within MC?

 

If you want to call me I can try to help you more, it might be easier to talk you thru it.

Joel,

 

I do this using the Mpsubrep post. Here is a Link to a topic about using this post with a Fadal.

 

You program your operations, then you enter the number of times you want it to repeat in the Miscellaneous Integers page.

 

Hope this helps.

have you tried clamping those 4 parts in one vise? I've found that unless your stock is perfectly dimensioned, more than two parts per vise and parts start getting thrown or pulled by the tools, even with two, measuring each may be necessary to avoid it..you can program the two parts with one work offset if you only have G54-G59 or E1-E8, if you have G54.1P1-P48 or whatever you can assign each part its own WO.HTH

Unless you're holding [2] pieces of stock and making [2] pieces from each, I'm with Rob; two separate parts in one set of jaws is some scary sh!t

We did this for years but I never liked it. Old school. If the stock is not saw cut in the clamp direction it's not usually a problem. But, having stops set at different part edges can be an issue.

 

We no longer use kurt vises and we now only clamp one part per holding device.

This is what we do now when we don't build dedicated fixtures:

Hello Gents and Ladies

 

Is there a mastercam file or model for a standard kurt vise anywhere to be found.

 

I have not been on the forum for quite awhile and it has changed.. a lot.

 

Please advise.

 

Thanks

Just wondering why you would reply to a 2 and a half year old thread?

[Threept82]

It had some information on what I was looking for. I thought.

[Thoob]

Oh, how about this?
