Small metal box

[awemawson]

Well for years, if I've needed to make a sharp bend in sheet metal, I'd cut a shallow groove where I needed the bend using a 1 mm disk in an angle grinder. OK for rough work but not too clever if it's out on show. So what I've done here is use the CNC mill to do the donkey work. The bending grooves were cut 0.5 mm deep using a 6 mm ball ended milling cutter, then the profile was cut out using a 6 mm normal end mill while he sheet was already mounted on a spoil board. As the box sides in this example were tapered it was much easier to lay it out in FeaturecAM than faff around with band saws or jig saws.

There's a bit more about it here:
