A Composite Evaluation Model of Sustainable Manufacturing in Machining Process for Typical Machine Tools

Abstract

Machine tool is the basic manufacturing equipment in today's mechanical manufacturing industry. A considerable amount of energy and carbon emission are consumed in machining processes, the realization of sustainable manufacturing of machine tools have become an urgent problem to be solved in the field of industry and academia. Therefore, five types of machine tools were selected for the typical machining processes (turning, milling, planning, grinding and drilling). Then the model of the energy efficiency, carbon efficiency and green degree model were established in this paper which considers the theory and experiment with the resource, energy and emission modeling method. The head frame spindle and head frame box were selected to verify the feasibility and practicability of the proposed model, based on the orthogonal experiment case of the key machining process. In addition, the influence rules of machining parameters were explored and the energy efficiency and green degree of the machine tools were compared. Finally, the corresponding strategies for energy conservation and emission reduction were proposed.

Economic and Energetic Performance Evaluation of Unreliable Production Lines: An Integrated Analytical Approach

“…This is a systematic method which consists of simplified measurement of basic data and the calculation of the indexes from the data. [30] studied the green performance of CNC (Computer Numerical Control) machine tools. In this work, a model of energy efficiency, carbon efficiency, and green degree is established.…”

“…Their results show that energy saving can be realized by completing machining as early as possible on a machine tool, and taking advantage of machine flexibility. Lv et al [18] illustrate a composite evaluation method for sustainable manufacturing in a machining process for typical machine tools in terms of energy efficiency, carbon efficiency and green degree, by considering the theory and experimenting with a resource, energy and emission modeling method. They propose corresponding strategies for energy conservation and emission reduction.…”

Sustainable Machining: Tool Life Criterion Based on Work Surface Quality

“…The authors have claimed that the approach has encompassed all the major aspects of machining sustainability such as energy consumption, material consumption, service consumption, and generated waste. Lv et al have established energy efficiency, carbon efficiency, and green degree models with respect to the five kinds of metal cutting machine tools: turning, milling, grinding, planning, and drilling [16]. Following the models, the authors have suggested measures for energy conservation and emission reduction for these machine tools.…”
