Sharp edge or radius which is cheaper?
The answer depends on the application. For bare ceramic, a chamfer may be preferred because during the manufacturing process chips can be encountered. If a print calls for sharp edges, a chipped edge could cause WIP to be scrapped. If, on the other hand, there is a .025 max chamfer callout and the edge is chipped .015, there is no loss. DfM (design for manufacturability) is important at INTA.
