Need Help!- Working with stock thickness material.

[svatchi]

Good Day. Has anyone run into this? Working on a project that uses stock thickness plastic material that has blind features dimensioned from the top surface of the part as it lays on the table. The materials carries tolerance of +/-.020 while the part requires +/-.010. In order to hold required tolerance, I need to fixture the top surface of the part at a plane parrallel to the table(Z=Zero). I also would need to cut radii on the outer edges of the parts. with material having varying thicknesses, the radii are not consistent. Any ideas? All are appreciated!

Maybe vacuum table is a right thing for you...
