Edge chipping of ceramic cutting tools.

A reassessment of test data from experiments on the edge chipping of ceramic cutting tools has been made. These data were originally from an EU programme on development of novel nanocomposite ceramic cutting tools, and were obtained with the intention of forming a baseline data set against which to compare newly developed materials. In the light of further developments in the characterisation of edge chipping behaviour in ceramics, the data have been re-assessed with respect to test scatter, to the use of a blunt Rockwell indenter relative to sharp indentation, and to place the complete data set into the public domain.
