Methodology for adapting metal cutting to a green economy

Abstract The advent of global warming, as attested by the Intergovernmental Panel on Climate Change (IPCC), has serious ramifications for various facets of the human endeavour. Manufacturing is one such activity that is poised to undergo significant changes for curbing green-house gas emissions. This paper presents schemes for reducing the energy consumed in machining and grinding operations — the workhorses of any typical manufacturing set-up. These schemes are based on the mechanics of the metal cutting process which have been well studied over the years. Besides lowering the energy drawn from national grids, such schemes will pave the way for improved energy-efficient manufacturing processes. In the foreseeable future, alternative fuel systems to power manufacturing processes together with both newer operations and schemes, such as those outlined in this effort, would have a positive impact on the energy consumption of the manufacturing sector.
