The report describes the machinability of two commercial grade polycrystalline high purity alumina bodies, a 94 and a 96 alumina, after being rendered friable as a result of immersion in 52 aqueous hydrofluoric acid as a function of time. It was found that in performing those machining operations where a single point tool was required, selected grades of carbide tooling were preferred to diamond single point tooling. The report covers the required machining operation with critical analysis of such parameters as feed, speed, machine time, redressing tool time and an estimated rate of output per eight hour day. Further, each machining operation is critically analyzed with respect to problem areas and suggested method to improve upon them are given. Author
