Toolpath help

[Anonymous]

Hi, I've been trying to make a toolpath for my model for a really long time now, and I finally gave in and is in need of help. I can not for the life of me get a toolpath that actually goes takes the slope into account... https://imgur.com/a/D7REBey Letter slot width is roughly 0.5 mm and my tool is 0.5 mm flat endmill. What happens is either a VERY long toolpath going from the top of the stock (Even with rest machining) to the bottom of the stock (and/or custom limits). Or it does not go through the slots and just nibbles the surface. What I would like is something that just takes the "slots" and just goes, in steps, down. Nibbling away layer by layer but still not milling the air more than absolutely necessary. Any suggestions on this?

Can you post the model To do this Go to File -> Export and save as a .F3D Archive File and attach it to your next post, if you can not post the file you can PM it to me or say in your next post you can not post the file and one of the Guys that do NDA work will help.

Its no problem to post the data. I'm more interested in help with it.

What are you going to be cutting it on 3 axes machine 4 axes? you have a lot of indexing moves in your file.

Wow, you got alot going on there. The short anwser is going to be that you need either smaller tools or larger letters. Even if your letters/numbers were on a flat plane you would not be able to get toolpath to generate from your selections because adaptive toolpath needs room to ramp into the cut, lead-in and lead-out moves and room to make its linking moves. It is compounded by the fact that your letters are extruded down through a slope so that your actual projected sizes are smaller than your endmill.

Thank you for the insight. And yes, I split it into lots of smaller operations cause one big got out of memory. I will try my best to make the numbers bigger. //Regards

One thing to do what will help to get the file size down, pattern the high lighted toolpath, if you need to edit the toolpath it is only one toolpath to work on if a change needs to be done as the pattern will update the rest.

I've been sitting and tinkering with the tool width and different modes, and while I can get it to finally go through the slots, I still can't get it to stop at the correct height.... Se picture. I made the tool width 0.3mm so to at least get traces plotted.

It is just the angle they are on what is the problem, you can trace around there top or bottom edge, stick a tiny cutter in there like you have tried what will leave the edges at a 90-degree angle.

The only real option is to have the letters straight or go with a tinny cutter it is the same thing done a different.

On a 5 axis easy as.
