how to cut in XZ plane

[belearner]

i would appriciate all the help from everyone.

Let say i have a ball 2.000 dia on a vise and i need to use a 3/16 ball endmill to create a radius on 1/2 ball (.8125R by .1875 full R ).

I try to work with XZ plane but it did not come out right, so here it is , i know this place is for help.

Thanks for reading this.

Can you post a file or explain better? I'm not exactly sure what you're trying to do.

Ya, I'm not sure what your trying to say.

At first your saying your cutting a 2" ball with a 3/16" ball endmill then you say you need to cut 1/2" ball.

OK, Thank you for your reply but i don't know how to post a file up here.

Let me put it this way: imagine we have half a ball with dia 2.000'' then there is a slot width .1875 by .187 deep (from surface of the ball )with full dia at bottom goes from left to right( center line of ball ).

I though i could use a .1875 ball endmill to create that slot but it did not come out right.

Thanks again for reading this.

u should run offset in centre not at tip

If you are using a "2D contour" tool path, and selecting a 3D chain, it will make the cut but it will not compensate properly. To get it to comp properly you will have to use one of the "3D surface" tool paths.

Yes, this method does work when using the 2D countour tool path. You will just have to offset your geometry.

Great, supper. Geometry offset and tip comp at center. work perfect. appriciated. Thanks thousand time.
