An experimental study has been made to determine the influence of machining on fracture strength (four-point bend) of two potential turbine ceramics, namely sintered α-SiC and hot-pressed Si3N4. Machining aspects involve (a) types of cutting such as (i) use of a rotary table with a horizontal spindle, (ii) use of a rotary table with a vertical spindle, (iii) lengthwise, and (iv) transverse; (b) diamond wheel grit-size effects; and (c) downfeed effects in one machining pass. Several commercial machining sources were evaluated on the basis of material strength.
