Hi all,

I just collected a cnc machine that I won on ebay.

Initially I will be working with 3.6mm ply. I need to cut out 60mm circles, 72mm squares and make 1mm grooves.

A 3mm end mill came with the machine is it a good tool to cut ply?

I imagine it is better to get the tooling set up right before starting to try and make cuts so can anyone advise me...
1)what tool would be best to cut out circles/squares in 3.6mm ply?
2)What tool would be best to cut a 1mm wide groove, 1.5mm deep
3)What speed should be set for the spindle?
4)What speed should I set for the spindle to track around the toolpath?
5)Can 3.6mm be cut in one pass?

thanks,
Gavin
