  • Developments in investment casting process—A

    2012-11-1 · Nowadays, dental crowns are also fabricated by investment casting using ice patterns, generated by rapid freeze prototyping. (Liu and Leu, 2003) carried out a study in which a comparison was made between the surface roughnesses of dental crowns produced from the ice patterns compared to wax patterns. It was found that the surface roughness of the dental crowns produced in the former …

    2005-3-1 · Machining is used to “cut” specific features into preformed blanks (e.g., slabs, bars, tubes, sheets, extrusions, castings, forgings, etc.) by manipulating a fast-moving cutting tool relative to the work piece on a special (usually computer-controlled) machine tool, such as a lathe, mill, or grinder. In the machining process, even though the cutting-tool material is considerably more durable than the work …
