machining with the recommended cutting fluid allows to note uniform wear process of a
major flank face and rake face of the tool at full absence
of a cutting edge microchipping, or total brittle fracture
of the LCC inserts. While for inserts made of standard
ceramics (mixed ceramic VOK-71) with or without
coatings wear processing was defined of microchipping
of the cutting edge, or brittle fracture of a cutting part of
insert.
