I should start with no more than .2mm of DOC, slowest rpms you can get from the router and no more than 4 or 5 mm/sec.
I have never tried 1/36 end mills with aluminum. Pay attention to how the cut “sounds” and be prepared for losing a few bits.
Thanks for all of the feedback… trying to decide if its better to cut the outlines of the squares in the center of the peice or if its better to start from the center and mill out all of the material.
Just worried about pieces flying about if i only mill the outline…
Any suggestions? Was also thinking a tab on the top and bottom of each individual square piece.
Are you sure you need such a small tool for that, I am honestly not sure what is possible with a 1/32" mill? It will be much much easier with a larger tool.
Tried doing it with a 1/16 endmill that snapped on the final pass :’(
I wasn’t using any lubrication or coolant. I was too scared to stand next to the machine as I thought the endmill might snap and go flying.
The reason for doing this with a 1/32 endmill is because the cutouts are meant to fit something specific and im afraid that if i go 1/16 or larger that it may alter the shape of the cutouts too much.
Should I try a slower speed (mm per second)? Use wd-40? maybe .1 or .15 depth per pass?
