Processes are considered from the position of synergetics occurring during cutting brittle inorganic non-metal
lic materials with a diamond tool, particularly in the working region between a cutting tool and material being
machined, cut material structure and diamond cutting tool evolution, and question of implementing a cutting
tool self-sharpening regime.
Keywords: machining, brittle inorganic non-metallic materials (BINM), ceramic, cutting tool (CT) diamond
Machining is an intermediate or concluding operation in
manufacturing technology for objects made of brittle inor-
ganic non-metallic materials (BINM), which concerns ce-
ramics and refractories, glass, and glass ceramics, single-
crystal, and concrete materials. During machining produc-
tion tolerances and unevenness are removed in order to ob-
tain the required object dimensions, and the required object
surface finish. Thematically organization of machining is re
action within a system of three elements: a mechanical ma
chine, cutting tool (CT), and object, for example refractory.
In this article cutting will be considered as applied to cir
cular cutting processes, although they are very similar to
those occurring with other forms of diamond machining,
drilling, grinding, and polishing. A circular diamond BINM
cutter, as a special case of machining, provides material cut
ting by means of a diamond wheel, fastened to a rotating
shaft of a cutting unit. A diamond cutting wheel has the
shape of a flat disk of alloy steel, at whose center there is a
circular hole, and at the periphery there is a diamond contain
ing layer of continuous or interrupted construction. The
thickness of the cutting layer exceeds the body thickness
(overhang) to a controlled value, and this prevents contact of
the rotating body with the object being cut and provides cut
ting product removal. A continuous cutting layer is often sep
arated into segments. A segmented diamond cutting wheel is
shown in Fig. 1 for cutting refractories of the chamotte type,
manufactured according to GOST 16115 . The distance
between segments (groove width) and length of segments
optimize cutting properties and wheel life; they are selected
taking account of BINM properties and cutting conditions.
