This paper implements a holistic decision approach for determining tool wear
and surface quality together with machining parameters such as cutting speed,
feed rate, depth of cut, and cutting passes during turning operations. As a consequence,
two machining optimisation models are formulated with the objectives
of maximising the material removal rate and minimising the production
cost so that the decisions regarding machining parameters can be determined
as well as the status of tool wear and surface quality between intermediate
cutting passes. The feasibility and applicability of the formulated models have
been tested through computational analyses, and a comparison made between
the two performance objectives. The results show that the integrated decisions
of machining parameters, tool wear and surface quality can be made and thus
avoid the application of expensive on-line equipment for measuring tool wear
and surface quality. Furthermore, the feasible removal of material during
turning operations can be achieved through proper selection of depths of cut
and number of cutting passes. The proposed optimisation models can also be
used to provide tool replacement schedules based on the number of processing
parts and cutting passes.
