Strategy for tenon?

Hi,

 

I need help. I've posted 2 pics and my .tap file as .txt. Not sure what would be of most use - please let me know. 

 

I am trying to router the tenons in the image. I am happy with the parallel toolpath except where it gouges right through the stock material between the tenons. I would prefer it to stepdown through the stock and remove it as well as produce the tenon. I have tried 2 and 3d adaptive and many other paths. I cannot seem to just get the tenons cut out, following the curve, and nothing else. Several toolpaths try to also do the engraving that I completed in another path successfully. I ran a contour path that left the stock material in place between the tenons. How do I get the spindle to raise up over the stock for this parallel? Or, some other path entirely...

 

Thanks!

Jim

So others can better assist you, could you share the Fusion file, or a sample file that contains the spirit of the issue?

Sorry for late response. Please try to use the following settings for you Parallel operation.

Maximum Stay-Down Distance = 0 guaranties that long transitions aren't used.

Full retract guaranties that all retracts are on retract plane.

I have the following result with these settings.

As you have Modelled the Text with vertical sides I am assuming that is how you want the job to look like, see image below, if so then the Engrave toolpath is not the correct one for the job, may I suggest using a 2D Pocket toolpath as shown.

If you want Tabs at the sides then you need to make your Stock larger or use Points to place Tabs at each end in between the Tenons as in the attached file.

I suggest that you use the 3D Adaptive toolpath to rough out the majority of the material around your Tenons and just use the Parallel for the Finish as it really is just a finishing toolpath.

The very small text around the edge of the model you will need to use a very small cutter (1/32) as you have all sharp corners in the text you will get the Radius of the tool so the finished text will not be exactly as you have modelled.

Anyway, try running the simulation and see if it is something close to what you want and is of some help :slightly_smiling_face: :slightly_smiling_face:

Thanks for your input. I was only focused on the tenon portions. If you look at the last photo I posted, I already ran the engrave portion using a 45 degree V-bit. I also ran a contour with tabs around the perimeter using a 1/4 flat end mill.

Well, I am baffled, why would you model the text as cutouts and then use a V tool to machine it, from the photo you posted it looked pretty messy to me but hey, each to their own as they say.

 

Yes, you had a Contour with Tabs but there was no Stock there to create the Tabs because you had a Stock that was a fixed size the same as the Model so in actual practice on the machine to run a piece of stock that size then there would have been no Tabs and most likely have the part cut model flying across the room !!!

I adjusted the setup for each toolpath. I am sure not ideal but I ain't no Fusion pro. I don't know how to model the letters other than flat bottom. I knew the V-bit would create a V groove and that was my intent. I'm still learnin. I think the engrave looks good. Here is a better pic. And a pic showing tabs, they came out great! I should also point out that this is a scaled down version of my final product. Testing to make sure I can get the right toolpaths and ultimately, the right outcome. Open to suggestion as I learn and I appreciate your insights and feedback.

I think I know what you mean by setting the text as cutout etc. I could just as easily have set the text flat on the sketch, no extrude and the engrave toolpath would have worked fine.
