Despite being a wasteful process, machining is often regarded as an important
manufacturing method due to the fact that it is a flexible and economic
process. However, in order to gain more cost-saving and enhanced environmental
performance, sustainability principles have to be incorporated into
machining technologies. A step-wise optimization procedure is proposed
based on axiomatic design (AD) principles for identifying an optimized sustainable
manufacturing solution that comprises combinations of minimum
and maximum levels obtainable within the constraints involved (cutting
condition, performance and sustainability). A case study involving three alternative
processes (namely conventional machining, high pressure jetassisted
machining, and cryogenic machining) is presented for demonstrating
the application of the proposed approach, which indicated that the suggested
procedure is able to facilitate an optimization process by varying the design
parameters (DPs) within a particular sequence. In the case study, a hybrid
model consisting of crisp and fuzzy AD analysis techniques was also used for
analysing the sustainability performances of the processes being considered.
The hybrid model is able to point out the most viable machining process that
satisfies all the sustainable functional requirements (FRs) by using information
content for indication purposes.
