I’m moving onto Aluminium now and could do with your advice on the following settings in Easel.inventables. I’m going to test cut a square out of 3mm aluminium, and will subsequently try 6mm, 10mm and 15mm thick aluminium as I have samples available.
I have read these but am still not clear what combination is a good baseline considering Ryans message in Link-1, but my setup is the same as Ryans in size:
But I am looking for someone to give me a simple baseline for all the settings to start from for my tests, so I at least don’t end up blowing out my 1/8th inch bit within 1 second of cutting.
Question-1: Could you tell me what settings to use as a baseline for cutting Aluminium (Aluminum for the Yanks), and any further things I should have included in my list below but didn’t?
DoC - 0.5mm?
FeedRate - 10mm/s?
PlungeRate - 0.5mm?
Speed - Makita setting ‘1’ (10K)
Endmill - single flute, upcut, 1/8th inch
MPCNC-Primo dimensions - 3’ x 2’ and 4" z-axis height (but will reduce using stacked planks from Link-1 info)
Router - Makita 700 series
Easel.inventables doesn’t have ‘tracoidial stepover cutting’ or ‘adaptive clearing’ from what I see.
Right now, I have no chip-clearing apparatus but will make do during these tests and buy the gear in.
You suggest ‘Husky 4gal air compressor’ but that’s only available in the USA.
Question-2: Do you know what other air compressor I can get that’s cheap and reasonably quiet on Amazon?
