Re: Determining flatness and parallelism rapidly
First Stab at this;
For flatness use a Surface Plate with a hole in the center to mount a LVDT indicator? Surface Plate would need to be twice as large as your part. Slide the part over the LVDT indicator looking for total range.
Mount another LVDT above the surface plate, opposite the first, so that it can touch the opposing surface to measure parallelism.
Downside is the surface plate may wear rapidly.
