Sorry for late reply, been busy.

I am using adaptive toolpaths with Autodesk Inventor HSM. I have used 2 flute, 3 flute, rippers. The only tool i didn't use was 1 flute. I have tested with tools diameter 10mm, 8mm, 6mm and had similar problems. Because of the nature of the workpiece i was mostly using long flute lengths (10mm x 45mm, 6mm x 35mm, 6mm x 20mm). I have tested with short flutes too ofc (10x26,8x20,6x16) and it's the same issue. The machine sound is so loud because the room is very small and echo is really loud on the camera. It's not that bad IRL but its not quite ether . Here is the last batch of broken tools



Doddy, i am not sure if i follow your questions but the frame idea was stolen from Jonathan's machine so i didn't do any calculations to be fair.

That explains why it looked quite familiar, Cunningly disguised by a different colour paint!:-)

So i am about to upgrade the machine with the combination of epoxy granite and concrete in a hope to eliminate vibrations and damping and hopefully have even better cutting performance. I got high quality epoxy granite Rampf Epument 140/8b, but i have only 100kg of it so to gain more weight of the frame, i will use concrete too. I would like to hear opinions if this would work. On the picture attached you can see how i will do this. Blue color shows where i wont use EG(have only 100kg), dark shows tubes filled with EG and gray is concrete (beton). I will also fill the gaps on gantry with EG and put the EG under the table. Will this work?

Hi Matt

Your machine looks pretty stiff so for cutting aluminium faster I would have a go with mist coolant. Lots of posts on here about how to do it so you don't fog up the workshop. Do you have a compressor ?

Also it might not effect things greatly but the concrete will shrink a bit when dry so might pull away from the walls. I'd try the mist coolant first though.

Husky what happened next?

Husky what happened next?

made some upgrades, here is recent: 7.5kw 24rpm eurospindel with other improvements. Steel table is not done yet but i might consider integrated turning table instead of that turning chuck.
