Help please, B-axis and WCS.

[Demon440]

We have a part that has already been programmed and ran using Master Cam X and now I need to post it and run it again because of a small change in the part. Anyway it was all going good until the B-axis needed to be positioned at 40 degrees for a feature on the part. (Mazak PFH 4800 horizontal mill) At that time it was quite a lot off. About an inch or two in X and Z. I know it has something do to with how the WCS is setup but I don’t know how or what to do. Any help would be very greatly appreciated.

Ekk I would say a file would help, can you share?

[Demon440]

Cant share the file. It's just like a block with a 40 degree angle on it. It works fine on the computer but when I post it and run it on the machine all the B axis stuff is wrong.

Did you use a WCS to get the orientation or just a T/C plane?

 

 

You should be using planes not a WCS to generate axis motion

[cadcam]

Like John is saying set your Named view not your WCS.

The wcs will say the the same name as before but the T/P will change to the view start there.

Thanks. I called our old cam guy asking for help and he said I should not even need to do anything other then use xform translate and put in the new part location. So now I’m having problems with xform. This is what I'm doing.

-Click "Xform Translate"

-Click on my part and hit enter.

-The translate dialog box comes up.

-I type in 25 in the delta Y box.

-Click on the "check" and then apply.

-Now the solid copy moves over in y.

-There is a wire frame and tool path left in the old spot.

-Now I’m stuck, I need to get rid of that old wire frame and move the tool paths over.

 

Sorry for the long newb post. One day I'll repay by answering newb questions.

This one is kind of difficult without a file. I know you said you cannot share, you might be better off checking with your reseller.

 

I am sure if you don't already, you can get them under an NDA to cover your a**

 

I sign these with my clients because of some of the work I do.

 

I am caught at the moment as to whether you need to move your part or whether you are trying to transform tool paths around to different parts on a horizontal. Or whether you are just trying to get a 40° rotation.

[Demon440]

Yeah maybe I'll contact the reseller.

Right now I'm wanting to move the part and the tool paths just a bit for the slightly different setup location from last time we ran it.

[Demon440]

update! I have Xform moving everything now the way it should and there is nothing left over. Only problem now is that it looks like when I back plot it's running in the old location. ?

[Charlie Pierson]

did you update your cplane, tplane, and wcs ??

[Demon440]

no. How is that done?

[Demon440]

Hey CadCam the boss said I could share this file to help us get the part made So you have mail.

[cadcam]

Yes sir cadcam at mastercam-cadcam.com this will do the trick.

[Demon440]

Thanks CadCam, I sent the file on Friday, did you get it. Anyhow, I'm still stuck but It's getting closer now. Now we are about 1.8mm too deep in Z and 1mm too far off in X. I found that when I was picking the wrong 0,0 point before. Now that I have that right it's much closer but still a little off. Wow this is getting real frustrating.

[Demon440]

Also I got Xform to move my part correctly now too. And when I re-pick the top of stock and depth, and then re-run it; everything looks right.

[Demon440]

Update! we got it. Details later it's time to go home.

[Demon440]

okay, here’s what went wrong...

First I was trying to move the WPC to match the numbers I was given by the operator. After learning this was not the right way to do things I eventually learned to use the Xform translate. Still the 40-degree cut was off... After doing the math and running back in fourth trying different stuff about 30 times. (Which was really good practice anyway.) I found that the operator was off by about 1.5mm in the Z location he gave me! After we corrected this it's cutting perfect! Anyhow thanks to everyone here helping out and listening to my newb gibberish. See I only received about an hour of instruction on MC before the other guy left, and no one else has a clue. soo yeah I'll be the newb for a little while.

Sorry did not get te file or I would followed up by now. Sorry.
