Über dieses Buch

This monograph presents a reliable methodology for characterising the energy and eco-efficiency of unit manufacturing processes. The Specific Energy Consumption, SEC, will be identified as the key indicator for the energy efficiency of unit processes. An empirical approach will be validated on different machine tools and manufacturing processes to depict the relationship between process parameters and energy consumptions. Statistical results and additional validation runs will corroborate the high level of accuracy in predicting the energy consumption. In relation to the eco-efficiency, the value and the associated environmental impacts of manufacturing processes will also be discussed. The interrelationship between process parameters, process value and the associated environmental impact will be integrated in the evaluation of eco-efficiency. The book concludes with a further investigation of the results in order to develop strategies for further efficiency improvement. The target audience primarily comprises researchers and experts in the field, but the book may also be beneficial for graduate students.

Chapter 2. Review on the State of the Research in Energy and Eco-efficiency of Manufacturing Processes

Abstract

Researches in the field of manufacturing processes traditionally focused on the mechanical performances, such as cutting forces, machinability, surface roughness, dimensional accuracy, etc. The energy consumption and the associated environmental impact of manufacturing processes had been overlooked in the past. Due to the soaring energy price and increasing awareness on environmental impacts, energy and eco-efficiency has become one of the most extensively researched topics in the field of manufacturing. New researches and papers have been published in order to improve the energy and eco-efficiency of manufacturing processes. However, there are few fundamental questions remaining unanswered. For example, “what does energy and eco-efficiency mean to manufacturing processes?”, and “how to evaluate them” still remains to be answered. The following sections present the currently available methodologies in the literature that attempt to answer those fundamental questions and define the research gap which still requires to be addressed.

Chapter 3. Methodology for Characterizing Energy and Eco-efficiency of Manufacturing Processes

Abstract

This chapter proposes the methodology of characterizing the efficiency of manufacturing processes from both energy and ecological perspectives. An empirical approach is used to first characterize the energy efficiency of unit processes. Based on derived energy efficiency models, the eco-efficiency can be evaluated accordingly.

Chapter 4. Energy Efficiency Characterization of Manufacturing Processes

Abstract

With the proposed methodology in Sect. “Methodology of energy efficiency evaluation for unit process”, this chapter selects a wide range of manufacturing processes to characterize their energy efficiency. The presented cases range from single cutting-edge machining (e.g. turning) to multiple cutting-edges machining (e.g. milling), from geometrically defined cutting-edge machining to geometrically undefined cutting-edge machining (e.g. grinding), from metal machining to thermoplastic processes (e.g. injection molding), from conventional manufacturing processes to unconventional manufacturing processes (e.g. electrical discharge machining). For each process, a number of different machine tools are presented in order to validate the proposed methodology.

Chapter 5. Eco-efficiency of Manufacturing Processes

Abstract

With the proposed methodology in Sect. “Methodology of eco-efficiency evaluation for unit process”, this chapter further characterizes the manufacturing processes in terms of their eco-efficiency. The characterization starts with processes where the main energy and resource consumption is only electricity, such as turning, milling, and injection molding. Then, a grinding case is presented to demonstrate and validate the proposed methodology for a more complicated case.

Chapter 6. Implementation Towards Improving Energy and Eco-efficiency of Manufacturing Processes

Abstract

This chapter firstly explores the mechanism of model coefficients, by decomposing the SEC model. Then, a clustered model for material removal processes are presented and discussed. The following section discusses the challenges of characterizing energy efficiency in industries, and proposes a modified methodology with a case study in a biomedical products and services company. The derived energy consumption information is also compared with current LCI database in order to improve its quality. Finally, the strategies for improving energy efficiency are proposed from different perspectives.
