lathe program stop then flip part

[Columbo™]

I have a part that is cut on an arbor. I remove .05 from the face and do some finish turning on the end where it gets faced. Then there is a program stop, and flip part. Is there a way to have the updated geometry get flipped compensating the .050. The way I do it now is using two machine groups and manually putting the programs together. This seems a little tedious. Is there a simple way?

 

Thanks

Columbo,

Check out the stock flip video I have this may help with your question.

Thanks Steve,

 

That was pretty cool. Just tried it and posted it. Output looks good except the post error. This is what I got.

( STOCK FLIP -> MISC OPS. function was programmed ! )

N1840M00

 

 

Guess I gotta look at the post. Any idea where?

 

Thanks

What type of lathe are you running this on.

Got the same warning with a stock advance move....

[Columbo™]

They are Okumas

 

I think if I just "#" out the error line all should be good. It doesn't seem to be linked to anything.

Am I right???????

This part of the post needs to be customized, as the sequence of code and the code itself varies so much from control to control there would be no way MC could put something together without alienating everyone that doesn't use it.

 

Example of a Myiano dual spindle dual turrent post transfer for the sub and the flip. Hopefully this helps some.

You can see I used a combination of misc. integers and Mastercam assigned parameters (stck_chuk_end_dz$) all of which coincide with the boxes inside the operations dialog.

You can look this up in the MastercamX_Post_Parameter_Ref.pdf (found in the documentation folder in MCX2/) and the V9 Post reference guide that I'm sure is on the FTP somewhere. It's how I learned.

The out put looks good, just this error.

 

This is a single spindle machine (actally they all are).

 

Does it matter if they are single spindle. I understand if it's a totally different location like a duel spindle situation but I am just flipping and shifing in "Z" .050 olong the same "Z" axis.

 

Thanks

I guess I'm confused on what your trying to do.

 

Flipped geometry will now be -.050 of Z0.0 ?

If so add the -.050 to the transfered Position data. Your stock will move with it after a regen.

[Columbo™]

Hymen, same file as other posting. It has the flip in it with the .05 translation. Ftp site under MCX2_Files directory as "groove question.MCX"

[ATG]

You should be fine, I use the stock flip on a single spindle all the time. Your just using this option in mastercam for your stock update your not actully using the machine to flip the part.......

I'm using this with a haas lathe works great.
