CNC tests: aluminum

Last time I tried how my CNC3040 machine deals with wood and plastic. Now it's time for some metal.

I tested on a piece of scrap aluminum, so unfortunately I have no idea of the alloy. The tool used was a 3mm 4-flute carbide endmill. Cutting depth was 0.4mm. For coolant I used Biltema brand "Multi-Spray".

The lower cut as seen in the picture was made with a feed rate of 50 mm/min and the one above it at 100mm/min. The faster cut looks cleaner.

I still need to do some more testing, but this machine does appear to be capable of light metalwork.
