Cutting Curved Aluminum Plate on ShopBot CNC

Tip: When cutting soft aluminium use alcohol as a cutting lubricant. Makes for much cleaner cuts and you wont have stuff building up on the tool.

cutting path not clear and sharp , I think your aluminum's not hard enough like 6061 may be 50xx

Recently on a 3/4" piece, I used a spray oil and the shavings detached. After the first cut the lube will sit in the groove, so I could let it run unattended. It took 10 passes.

It's crucial to see the bits flying off or the aluminum just re-agglomerates in the groove.

Thanks! It's a variable speed router, abt 5,000 rpm, .05" sec. No cooling.

Hey this is great! Would you mind sharing your spindle speed and cutting speed with us? It looks like you didn't use any cooling, is that correct?
