dc.description.abstract |
The manufacturing industry largely contributes to the economy of a country. Thus,
manufacturing by material removal processes leaves a significant environmental footprint.
This is caused by the influence of process energy, resources, and releases. Due to that,
increased attention on sustainable means of machining operations can be seen today. Thus,
environmental sustainability assessments and preventive measures are being researched for
promoting green manufacturing. In conventional machining, milling is a widely used
machining method in the production and manufacturing industries. Thus, the purpose of this
study is to assess the environmental performance of milling machining in an industrial setup.
A literature review is conducted to understand the requirement of empirical assessment on
sustainable milling and to identify the factors contributing to environmental damage while
identifying sustainable machining practices. To conduct the empirical assessments, an
industrial milling operation is monitored. At the experiment stage, different consumables and
releases are identified and monitored such as power consumption, workpiece material usage,
tool material, and coolant while controlling the machining parameters and the tool path.
Design of Experiments were used to efficiently manage the controllable machining
parameters relevant to environmental performance. The contribution to the environmental
damage is analysed and quantified according to the ReCiPe endpoint impact assessment
method using SimaPro® (Version 8) life cycle assessment (LCA) software following the
guidelines of ISO 14044.
The review revealed several factors that are significantly contributing to the environmental
impact. Further, a number of operational level improvements were identified to improve the
environmental performance. The results identified the electrical energy consumption and
workpiece material usage as the most influencing contributing factors to the adverse
environmental impact. Further, an operator‟s guide was also developed to harness the
operational level savings to ensure the better environmental performance of milling. |
