Manufacture of basic parts of modern machinery and instruments of precision mechanics
often causes difficulties especially for small-scale production. This is due to their
complex configuration, and the presence of surfaces with precision of, for example, the
diametric dimension corresponding to IT5, IT6. Qualitative production of such surfaces
is achieved on modern multi-purpose CNC machines, but only by using non-trivial
technological solutions and techniques. Thanks to the proposed method of correction of
tool position we improve the manufacturing quality of precision surfaces of the parts by
edge cutting processing on multi-purpose CNC machines in small-scale production. The
technique envisages execution of the work passes of finishing (final processing) with
constant cutting depth and correction of the tool position by measurement results of the
withstanding size. Application of this methodology provides accurate diametrical sizes of
the surfaces of details made of structural steel, magnetically soft materials, titanium and
aluminum-magnesium alloys corresponding to IT5, IT6. Formalized methodology
automates determination of the necessary correction.
Keywords: part, precision surface, accuracy, CNC machine, instrument, position, correc-
tion, quality.
