I am in the process of setting up for a small CNC project where I need to cut two pieces out of 1/2" and 1/4" aluminum. My CNC machine is small a Sig X2 type.
The first piece is an oval plate 1/4" thick with no holes. I have used wedges to hold 1/4" stock before, but I have not tried cut out a pattern from the center where the piece is released from the stock. I was planning on using my current wedge setup but I worry that the final cut may damage the edge of the piece when it releases. Should I worry. I was also thinking of maybe leaving a small connection point so the piece does not release fully? Maybe someone has a better solution as I have limited experience with different holding methods.
The second piece is a 1/2" by 1" bar stock that I need to make three holes and profile the 1/2" edge of the bar stock. Besides making it a two part procedure where I cut the holes then use the holes to clamp the bar, then profile the bar's edges. I would like to do all of the operations at once, but it would require access to all sides except the bottom. I am at a loss on this one, any suggestions?
I am using a jig plates now but I do not have a vacuum setup.
