helical bore problem

Hello everyone,
I am running wf3 on a Haas vf3ss. I want to create a helical trajectory to hog out a hole. The problem is if I use machine -circ_interpolation - arcs only the Haas runs the tool in a circle without moving down in z, if I use points only the tool path circles are not all concentric and gouges the part! I would also like to add profile stock allow and axis shift if possible

thanks for any help rrr

Tony, could you verify the link, please? It seems to just bring me back to my original post, just like using arcs only, going in circles but not cutting anything...

I'm aware of setting up customize with entry angle, clear dist., lead radius....

thanks, rrr
 
hi David,
not if it's done using arcs only

Here is the link again. If it does not work look for helical milling in the forum around August 27th

Your code actually looks good, except it does not have any z-move in your circular routine. How does the cl output look like? Does it show in the customize a helical move?
Maybe your post is not setup correctly, to allow z-move in circular interpolation? Not to familiar with g-post since we use campost.

cl looks good, shows helical in customize, and vericut- the work around was to use points only, that added the z output but it produces a gouged part

What version Wf are you using. You mind sending me the mfg file as long it is not WF5.
I would like to take a look. It may sound like it is a post issue. I use arc-only, and it works good for me.
If you use points only it will generate a lot of points, and maybe your post is trying to do an arc fit possible, or is it outputting a series of points as well?

or just send me the cl-file (arc_only and points only)

rrrhaas,

looked at your files. I do not see anything out of the ordinary. I brought it into W4, did not make any changes, just regenerated the cl-file and posted it thru on of my posts. Looks good. Nothing wrong with the cl-output

Look at you post processor. Under motion -> circular click on the ARCSLP Interp. Tab. Output ARCSLP blocks should be activated (that is if you are using g-post).
It looks like your post is not suporting or is not set for helical interpolation

I am not seeing any XYZIJK in the g-code file.

As Tony suggests edit the gpost file and turn on the arcslp. You may get an alarm when using K. So disable K output with ARCSLP. Test the tape output XYZIJ and make sure you set the circle prep codes and XYZ as non-model.
