项目摘要

9613111 Komanduri The use of cutting fluid in machining has been the standard practice in metal working inudustry. Recent environmental constraints necessitate innovations on dry machining or other techniques. The research project is to develop novel nanocoating technologies on cutting tools for dry machining. This research project will conduct the following investigations: (1) synthesize the characterize multilayer nanocoating systems on cemented tungsten carbide cutting tools by closed field unbalanced megnetron sputtering (CFUMS); (2) optimize the nanocoating architecture, thickness of the carbide layer, metal interlayer thickness and number of layers, and deposition conditions of CFUMS for a given application; (3) evaluate multilayer nanocoating systems in dry machining of selected work materials over a wide range of feeds, speeds, and depths of cut; (4) evaluate the performance of the nanocoating systems in dry machining and compare it with uncoated as well as candidate commercial coating systems; (5) determine the micromechanisms of tool wear and relate to the structure and composition of multilayer nanocoatings and (6) assess the payback of dry machining with numerous nanocoatings and identify new applications for nanocoatings as well as for dry machining of other materials. This project is a collaboration between an industrial partner and the University. The outcome of these studies could provide useful findings for the machining industry.

9613111 Komanduri切削液在机械加工中的使用已成为金属加工工业的标准做法。最近的环境限制需要干加工或其他技术的创新。该研究项目是开发新型纳米涂层技术的刀具干加工。本研究计划将进行以下研究：（1）利用闭合场非平衡磁控溅射（CFUMS）技术在硬质合金刀具上合成表征性的多层纳米涂层系统;（2）针对特定应用，优化CFUMS的纳米涂层结构、碳化物层厚度、金属夹层厚度和层数以及沉积条件;（3）在宽范围的进给、速度和切削深度下，评价所选工件材料的干式加工中的多层纳米涂层体系;（4）评价纳米涂层体系在干式加工中的性能，并将其与未涂覆的以及候选的商业涂层体系进行比较;（5）确定刀具磨损的微观机制，并与多层纳米涂层的结构和组成相关;（6）评估使用多种纳米涂层的干加工的回报，并确定纳米涂层以及其他材料的干加工的新应用。该项目是工业合作伙伴和大学之间的合作。这些研究的结果可以为机械加工行业提供有用的发现。
