MAN: Modern Applications News;May2008, Vol. 42 Issue 5, p14
The article discusses the author's machining job experiment using Incoloy 901, a super alloy used in high-temperature applications. The author and his colleagues prepared for two eventualities after examining the part. He then planned to try some reinforced ceramic inserts to do much of the roughing and finishing but use some grades of carbides if the material proved too rough for the ceramic. Information on the three operations used by the author and his machinist to machine the part is also given.
