Environment Friendly Coolants Strategies for Machining

越来越多的证据表明，加拿大经济正开始摆脱过去对大宗商品的过度依赖，转向主要依赖技术、生产力和熟练劳动力的附加值行业。汽车行业仍然是加拿大最大的附加值出口行业，出口额为850亿美元，几乎是2009年低迷水平的两倍。战略性增值部门的出口激增是这一过程的前沿，最终应会转化为更多的投资、产出和就业。加拿大制造业要想适应这种变化，就需要在熟练的劳动力、高效和可持续的运营以及新的机械加工技术方面应对几个挑战。金属加工液(MWF)对于提高刀具寿命、改善表面光洁度和从切削区去除切屑的加工过程是必不可少的。然而，金属加工液(MWF)因其经济性和环境相关问题而受到广泛质疑。这项研究计划的更广泛目标是通过研究经济和环境可行的新解决方案来实现更可持续、更多生产和更有利可图的加工工艺。为此，引入和测试用于加工工程材料的混合冷却液策略，为更高效的加工过程和更好的表面质量开辟了可能性，同时减少了加工过程的环境负担。这需要对不同的切割参数组合进行全面的实验研究，包括新的和混合的冷却液策略，以加深对这些参数对工艺机理的影响的了解。在以往经验和跟踪记录的基础上，拟议的研究方案旨在开发所需的知识、数字模型和工具，以解决与难加工材料的加工有关的可持续性和技术挑战，包括刀具磨损、表面质量和完整性。这将使这些材料在整个制造业得到广泛应用，并将为加拿大制造业在全球市场上创造一个更具竞争力的环境。

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.
