Mechanical se- rial sectioning using a Robo-Met.3D provides time and cost savings over manual polishing while also allowing for micron-level precision through engi- neering-scale volumes on the orders of cubic millimeters . Lastly, data resulting from a Robo-Met.3D is useful for investi- gating studies of academic interest and aiding root cause analysis in developing acceptance criteria for parts. ~AM&P For more information: Thomas A.
