Re: [CAD_CAM_EDM_DRO] Newbie: How to clamp material to cut shapes out of the center?

Is it possible to clamp the stock to a wooden base, then as the profile gets
close to being milled out, screw it down through the milled-out slots? Or,
are there holes on the tag that could be located first, then screwed down
before milling out the profile? If only one hole, start milling at the
opposite end, then by the time you get back around there, the screw will
hold the part. Also, I would use 'up-milling' (with respect to the part)
for that, rather than 'climb-milling'. You'd still have to clean up a little
'tit' at the end, though.
