I've just finished designing my rear suspension which includes a number of axle brackets. I sent out a test with the same DXF to get cut by water jet and cnc plasma.
As expected the plasma does have quite a bit looser tolerances. For some things the tolerances won't matter so much, however it can cause issues for things such as bolt holes. In my test, it looks like I'll have to under size the holes a little and ream them out myself once the parts are cut.
I had really high hopes for the CNC plasma, since I'm thinking of purchasing a small table for personal use. Unfortunately I was a little disappointed. IMO, a plasma table is nice for prototyping, but for production work I'd probably still lean toward using a partner with a laser/water jet.
