How to design checkering

[Anonymous]

I am new to Fusion and am still at the point of not knowing what I don't know, so please forgive me if the answer to my question is obvious. I have .igs files for the grips of a 1911 pistol that I have put through the CAM process and can cut the solid bodies.  However, I would like to be able to add  checkering to the outside of the grip panel.  I can certainly do this by hand, but it would be great if it could be added as an additional toolpath.  Problem is that CAM is my strong point (if you can call it that), design is my kryptonite.  

I would think it would be relatively simple to use a v-carving bit to accomplish the cuts, but I have no clue where to start in terms of design. Any help or nudges in the right direction would be greatly appreciated!!

I've included a link to the part I've been working on.

I can't see the model.  I would be happy to take a look and offer some suggestions.

Hi @Anonymous

I have been discussing your question with @al.whatmough who is our PM for CAM.

There are a couple ways you could attack this - a modeling way and a CAM way, but we can't seem to get access to the link you provided.

Can you give us access?

Thanks

Thanks for the replys! Here is a link to the current model.

What kind of pattern do you want?

It may be easiest to just use a parrallel toolpath at 45 deg with and agressive stepover. 

You can even at 90 deg passes.

You could use a containment boundary to keep the toolpath to one area of the surface and a project toolpath to do a nice outline arround that area.

That's seems like a good, simple solution. Most traditional panel checking is done at an angle such that the resulting diamond are generally 3 times longer than they are wide. This results in an angle of about 60 degrees. Any thoughts on how to do that? Also, what if you want to exclude an area inside the boundary, like a geometric design or logo? See attached image for examples.

Thanks in advance for your help and time!

if you want to exclude an area, add that to the machining boundary  or add surfaces as check surfaces.
