Taking Surface Finish to a NEW Dimension

With the increasingly complex geometries being designed and manufactured today, and the rise of parts being printed via Additive Manufacturing, growing concerns of how to achieve the desired surface finishes without losing critical geometries and tolerances has never been more relevant. What is surface roughness and how do you discuss it? With so many manufacturing techniques today, what are the essential parameters for surface roughness and what do they mean? ALWAYS think about the finish before you start.
