Problem- bad code

[Tumbleweed Tim]

Anyone got any ideas??
Why won't this work? It won't get the #14 offset. Trying to turn a .750 sphere with a .375 dia. neck with a .120 wide 0156r using both edges. I can't get it to get #14 at X.75Z-.375. cuts back side with #4 only. Is this possible to do like this?

To use offset 14 with tool number 4 you need to say T0414, also check that your tip data is correct on your tool offset page. For a tip that points straight down it should have an 8 for tip direction.

Try that. I have never used offsets like that within a LAP cycle. Let me know how it turns out.

I seriously doubt your gonna be able to switch offsets like that since cutter comp would be totally lost.

This will probably work, but you must remember the 6 digit tool offset, and the order that it reads in. Just like in the tool layout page, R T O, radius, tool, offset. I think if you call the offset with 6 digits you'll get what you're after.

Thanks,

Draws fine on the screen. Cuts the shape of football. Does not even show tool going into the part when it gets to start G87. Thanks for your input and I did run the program as copied and pasted.
Okuma can't get it to go either and they say it should work, Really wierd.

Thanks,
Tim

You can try -should work-you are just moving the rear side by a variable

Just check whether the variable should be a minus or a plus value

Wow,
Now that looks sneaky. I went to full radius tool, but I will try that some time when I can play with it. Thanks.

Now I need to adjust size. I get .750 at center and .7507 everywhere else on the sphere diameter. Is in tol, but I am thinking I can get closer. Offsets are .06/.06. I am getting a little spiral pip at center.
I don't need bearings but I want them.
Thanks,
Tim
