ABSTRACT
Processes of wear intensity at diamond drilling are complex, integrated and relatively ill-known. Conventional experimental knowledge records (usually tables, graphs and/or equations) are not suitable for an efficient uncertainty reasoning. A fuzzy knowledge base is a suitable framework for acquisition of vague, sparse and inconsistent knowledge. A revitalization of Wear Intensity records and re-used literature knowledge items is a retrospective application of knowledge engineering algorithms. This is an ad hoc process and a general theoretical background does not exist. Therefore this paper presents a detailed description of the technique of the knowledge base establishing. No a priori knowledge of fuzzy mathematics is needed.
