Abstract—The automated design of special machine-tool attachments for the machining of high-tech parts
and assemblies in order-based production is considered theoretically and experimentally. New models and
methods are discussed.
Keywords: special machine-tool attachments, automatic design systems
The design of special machine-tool attachments
for the manufacture of components and assemblies
used in airplane engines and other machinery must
take account of some specific requirements.
(1) High manufacturing precision.
(2) Great variety and complexity of the compo-
nents and assemblies employed. That significantly
limits the use of universal machine-tool attachments
and entails the design of sets of attachments, differing
(3) Diversity of the manufacturing technologies for
the components and assemblies. That calls for a corre-
sponding variety of machine-tool attachments.
(4) The manufacture of components and assem-
blies from materials that are hard to machine. For
example, considerable cutting forces are required in
that case. That imposes more rigorous requirements
on the rigidity and strength of the machine-tool
attachments and also complicates their design.
There is growing interest in the automated design
of machine-tool attachments. The following topics
were addressed in [1–4]: methods of automated design
of machine-tool attachments and optimization of the
design; the creation of a special language for design
description; the development of iterative design-deci-
sion algorithms, with tables of criteria; mathematical
description and selection of the basing configurations
for the workpieces; the formulation of algorithms for
calculating the forces and determining the expected
geometric precision; and the accumulation of experi-
ence for use in automated design on the basis of CAD
systems and databases of universal design elements.
The degree of standardization of basic components
in machine-tool attachments was assessed in . In
particular, a standardization coefficient was proposed,
so as to save time in the design process on the basis of
standardized components, modular design principles,
and a library of standardized components for machine-
tool attachments. Modular design of machine-tool
attachments has been considered by researchers includ-
ing Senthil, Fuh, Kow, Peng, Wang, Liu, Wua, Gao,
Chen, Mervyn, Nee, Girish, and Ong .
A method of designing machine-tool attachments in
dialog mode, on the basis of a database of structural ele-
ments, was developed in . Methods of automating the
initial stages of design on the basis of expert systems,
morphological analysis, and cost/benefit analysis were
developed in . Others addressing this topic include
Kakish, Zhang, Zeid, Boyle, Wang, and Chen .
Research into the use of genetic algorithms and neu-
ral networks in the automated design of machine-tool
attachments, as well as optimization procedures, has
been conducted by Ishikawa, Aoyama, Hamedi,
Choubey, Kaya, Hashemi, Kulankara, Satyanarayana,
Melkote, Shaharouna, Izman, Ganjia, Namazian,
Shojaeic, Lai, Luo, Lin, Kumar, Subramaniam, Seow,
Zhou, Zhang, Qin, King, and Hutter .
Analysis of research on the design of special
machine-tool attachments and practical verif ication
at manufacturing enterprises reveals the following
(1) The creation of new designs for machine-tool
attachments is based on expert assessments. Consider-
able time is required in finding and analyzing relevant
information and in the design process and the formu-
lation of design documentation.
(2) Only general aspects of the basing of workpieces
with complex seating surfaces are taken into account.
(3) Little attention is paid to the design and manu-
facture of the basic components of machine-tool
attachments. That reduces the quality of the designs
