Cutting 1.6mm Aluminium sheet - askaluadmin - 01-30-2018
I’m looking for guidance for a starting point to “cut out” a design from 1.6mm aluminium sheet . I see reference to a Video with settings that Ryan posted about a year ago but I can’t find it and having read through some of the posts on the forum I can’t find any basic settings to start out: X and Y speeds, depth of cut, accelerations and router RPM etc. I plan to use a 3mm bit and accept that with a Makita router any suggestions would only be a starting point but any guidance would be appreciated. Using Estlcam 10 as the CAM generator and controlling from an SD card.

1mm depth of cut 15mm/s x/y 10% trochoidal length 50%width .05mm oscillation. That’s my starting point, then I adjust from there. You might be able to do full depth of cut. Also, you have to have some way to get the chips out of the cut, vacuum, or air blast.

I think you should try them, in wood or plastic. Test cuts are a way of life. Make sure your file works in something softer first and then move up to metal. Save a ton of bits that way, might also be best to start with some cheaper ones. The expensive ones usually have very specific purposes and at $30 you might have the wrong ones. Some require coolant some will not work with coolant, etc.
You are talking about speed settings in estlcam control, are you positive you didn’t upload them the the board? How do you actually run your files?
You can watch some videos from the video page and do some visual comparisons to see if your speed is at least close.
