Attempted engraving aluminum for the first time on my Shapoko. I used a 60 degree V-bit at 30K rpms and a travel speed of 5 ipm. It came ok for what it is, but it doesn’t seem like it cut it seems like it just shoved it around.
Anyone have any experience they could share? I’m going to attempt cutting some shapes out of 5052 for water tanks using an O-flute .125” end mill. Any advice would be appreciated!! TIA!
Do you have to use 5052?
It’s gummy and difficult to machine.
Rather than a V tool, perhaps a #501 or #502? The rounded tip will hold up better, but feeds and speeds are still going to be difficult — is coolant an option?
Yeah I’d expect troubles with 5052. Should be doable but probably not super fun or satisfying to cut.
I imagine it’s a requirement for the bends in the tank? If it doesn’t need to be formed (maybe it’s just a badge you’re cutting 
) then I’m with Will in that another material will serve you better.
I already have the 5052. I found a place that will cut my components for $50. May just do that.
Save myself the aggravation.
The tread plate I believe is 3003. I am going to try a coated 3 flute 30 degree v-bit and increase my travel speed.
The tread plate pictured was a scrap piece to see if I can engrave the tuna. I am replacing the running boards on my boat trailer with the aluminum diamond plate. Each running board will have a different fish engraved on it. Dolphin, tuna, wahoo, marlin.
