I’ve got a thin sheet of aluminum (about 0.48mm) that I’d like to cut a simple shape out of.
I’ve got the Soft Metals bit set from Inventables but not sure which bit to use or if there are any other special considerations.
Anything I should know or keep in mind before I start cutting?
I just used the two flute 1/8 end mill and standard settings from easel for my first cut in aluminum, work great made my first part and no problems. there is a search function for more information if you are wanting to do more that just a simple cut.
Cut fast and shallow. Like crazy shallow.
The aluminum you have is really thin so… 2? passes.
And make sure your clamping is good!
The masking tape / CA glue method of hold down works very well on thin metal.
This is a must, as in something that keep the whole sheet down - otherwise it WILL lift.
I have cut 1mm alu sheet in one pass, worked fine for me. 2mm bit at 12ipm at full depth.
Before cutting thin aluminum sheets, choose the right size drill bit, use appropriate speed, lubricant, secure the workpiece, employ proper cutting techniques, adhere to safety regulations, and conduct testing and practice.
