This is a fixture I made for milling a product I'm manufacturing from
1/2" acrylic sheet. I also use it for milling circuit boards and for
engraving various labels.

The fixture is made from Azek (white plastic lumber found at Home
Depot). There are 1/8" pins for locating the work. The copper piece is a
1/2" coupler which I use to zero the x&y axes with a Mach3 macro. The
rubber seal is 1/8" neoprene, and it sits in a 1/8" x 0.090" deep groove.

This was my first shot at this thing, and it's doing what I needed it
to do. It's easy and cheap enough to crank out specialty fixtures as I
need them, with Fusion 360.


Very nice. I just bought a new table for my Taig. (I repurposed the
old one to a mini cnc lathe project.) I may put mine back together
again someday.

There are little jobs the Taig really does well if its adjusted properly.

So are you cutting through, leaving a skin and breaking loose the parts
when you take them off the fixture, or using a draw through spoil board
made of MDF?

Are you using high volume (blower or shop vac) or are you using high
vacuum? If using high vacuum are you employing a vacuum reservoir?
