The appeal of lightweight materials like titanium and high temperature corrosion resistant materials like nickel alloys to the automotive and aerospace industries is marred by the difficulty involved in machining such alloys. The machining of these alloys is plagued by high temperatures and adhesion which eventually lead to severe damage of tools and the machined alloy. However, machining is an essential part of the production of metal parts, even cast parts require some form of machining. Although the manipulation of machining parameters have been observe improve the life of the work tool, it bears little influence on mitigating adhesion or wear of the machining tool. The difficulties of machining can be reduced by the employment of lubricants and coolants (metalworking fluids). Metalworking fluids have proven essential to the machining process, controlling temperature, reducing friction as well as eliminating debris from the machining zone. However, present metalworking fluids posse adverse environmental issues, while other proposed cooling techniques do not completely eliminate the need of these fluids. Therefore, current lubrication and coolant solutions do not adequately or efficiently solve the issue of working with difficult-to-machine alloys. A practical solution to this issue is the application of environmentally friendly metalworking fluids, which is the basis of this research. This study will investigate the influence of several environmentally friendly metalworking fluids and additives types on the machining of lightweight alloys. Thus allowing the introduction of environmentally friendly alternatives with superior lubricity to current metalworking fluids. In addition to the vast environmental advantages, there would also be cost benefits due to the improvement of the machining process. It would also establish a better understanding of the interactions of environmentally friendly additives, metalworking fluids and the machining process. Finally, the results of this project will increase the competitiveness of Canadian aerospace and automotive companies by increasing the quality and throughput aspects of processes used by the manufacturers while providing a positive impact on environmental indicators.

钛等轻质材料和镍合金等高温耐腐蚀材料对汽车和航空航天工业的吸引力因加工此类合金的困难而受到损害。这些合金的加工受到高温和粘附的困扰，最终导致工具和加工合金的严重损坏。然而，机械加工是金属零件生产的重要组成部分，即使铸造零件也需要某种形式的机械加工。尽管已经观察到加工参数的操纵可以提高加工刀具的寿命，但它对减轻加工刀具的粘附或磨损几乎没有影响。使用润滑剂和冷却剂（金属加工液）可以降低加工难度。事实证明，金属加工液对于加工过程至关重要，可以控制温度、减少摩擦以及消除加工区域的碎屑。然而，目前的金属加工液存在不利的环境问题，而其他提出的冷却技术并没有完全消除对这些流体的需要。因此，当前的润滑和冷却剂解决方案不能充分或有效地解决难加工合金的加工问题。解决这一问题的一个切实可行的办法是使用环保型金属加工液，这是本研究的基础。本研究将研究几种环保金属加工液和添加剂类型对轻质合金加工的影响。因此，可以引入具有优于当前金属加工液润滑性的环保替代品。除了巨大的环境优势外，加工工艺的改进还会带来成本效益。它还将使人们更好地了解环保添加剂、金属加工液和加工过程的相互作用。最后，该项目的结果将通过提高制造商所用工艺的质量和产量，同时对环境指标产生积极影响，从而提高加拿大航空航天和汽车公司的竞争力。
