4th axis helix bore issue

[PetePO]

Hello, I have a problem with creating toolpath for 4th axis containing helix bore.

Here is the part. First I need to drill all the holes then to make them bigger i wanted to use helix bore with end mill. With drilling there is no problem(using drill option from multiaxis tab) but when I try to use helix bore there is no way to select good entities. Because this solid is empty inside there is no 2d wireframe of arcs . I tried roll with no success, it generated only splines, same with silhouette boundary. Is there any way to do it with 2d helix bore?

Hi Pete,

Welcome to the forum, You will have more success uploading a file. If you cant use the one you have draw something similar

Need to use Solid Hole axis to create the 2D geometry you need. That will also give you what you can use to create a plane if holes are no co planer. I would program a set forward at one index and a set from back to front then transform rotate them and call it a day.

I threw this together and everything worked with the solid only with no issues. Notice how I did what I was talking about with the Zig Zag process then transform them. All the hole programmed with drilling milling in 6 operations. No wire frame all solid driven.

Sounds like he has a surface model.  Use "solid from surfaces" then jump straight into Ron's file.
