There is growing evidence that the Canadian economy is starting to pivot away from its past over-reliance on commodities, into value added industries that rely primarily on technology, productivity and skilled labor. Automotive industry is still the leading Canada's value-added exports, at $85-billion - almost twice the depressed levels of 2009. The export surge from the strategic value added sectors is the leading edge of a process that should eventually translate into more investment, output and jobs. For Canadian manufacturing sector to be up to this change it needs to address several challenges in terms of a skilled workforce, efficient and sustainable operations and new machining technologies. Metal working fluids (MWF) are essential for the machining processes to increase tool life, improve surface finish and chip removal from the cutting zone. However, metal working fluids (MWF) are being questioned extensively for their economics and environmental related issues. The broader goal of this research program is to achieve a more sustainable, productive and profitable machining processes by investigating economically and environmentally viable novel solutions. To this end, introducing and testing of hybrid coolant strategies for machining engineering materials opens up the potential for more efficient machining processes and better surface quality, while reducing the environmental burden of the machining process. This entails performing a comprehensive experimental study of the different combinations of cutting parameters including novel and hybrid coolant strategies to develop an understanding of the effect of these parameters on the mechanics of the process. Building on previous experience and track record; the proposed research program aims at developing the knowledge, numerical models and tools needed to address both sustainability and technical challenges associated with machining of difficult- to -cut materials, in terms of tool wear and surface quality and integrity. This will allow wide spread application of these materials throughout the manufacturing sector and will facilitate a more highly competitive environment in the global market for Canadian manufacturing sector.*****
