Grinding is one of the most essential and costly manufacturing processes accounting for about 25% of the total machining expenditures in industrialized countries. Virtually every manufacturing company in the world relies on the grinding process to create components with precise dimensions and high-quality surface finishes. Grinding is of strategic importance to the Canadian economy because it is critical to myriad industries including the automotive, aerospace, shipbuilding, food, energy and medical industries - yet there are very few grinding researchers in Canada.****To address this need, the overall goals of my research program are to contribute to the fundamental understanding of the grinding process using both conventional and super-abrasive grinding wheels and to continue to develop novel grinding technologies that can be transferred to Canadian industry to improve the productivity, reliability and quality of the grinding process. For example, by applying new coolant delivery techniques to the grinding process my research has enabled a Canadian aerospace company to significantly increase their productivity. Recently, my research group has discovered that inscribing spiral-shaped grooves around the surface of a flat (non-profile) grinding wheel can further improve grinding productivity by enabling up to 120% more material to be removed while still maintaining high-quality workpiece finishes. We have also developed a corresponding innovative and practical grinding wheel grooving system that can be readily retrofitted onto existing grinding machines (including both manual and computer numerical control grinders) making it easily transferrable to Canadian industry.****The specific objective of the proposed research is to build upon my successful flat (non-profile) grinding wheel grooving research by enabling profile grinding wheels to be grooved. Profile grinding allows complex shapes to be machined into very hard materials such as superalloys, high-carbon steels and ceramics. The ability to groove profile wheels will enable the tangible benefits of grooving to become available to a much wider range of grinding applications in industry including jet engine rotors and blades, gears, bearing raceways, drill bits and cutters.****Key outcomes of the proposed research are to develop:***1. innovative and practical grooving solutions for profile grinding wheels ***2. corresponding grinding computer simulators that can determine optimal wheel grooving geometries, re-grooving intervals and process parameters for flat and, ultimately, profile grinding wheels****I have a solid track record of success in this field and the proposed grinding wheel grooving research will continue to make significant contributions to the advancement of grinding technology and will establish and develop Canadian expertise through the training of highly-qualified personnel in this precision machining process.**

磨削是最重要、成本最高的制造工艺之一，约占工业化国家机械加工总支出的 25%。 世界上几乎每家制造公司都依靠磨削工艺来制造具有精确尺寸和高质量表面光洁度的部件。 磨削对加拿大经济具有战略重要性，因为它对包括汽车、航空航天、造船、食品、能源和医疗行业在内的众多行业至关重要 - 但加拿大的磨削研究人员很少。****为了满足这一需求，我的研究计划的总体目标是促进对使用传统磨料砂轮和超硬磨料砂轮的磨削过程的基本理解，并继续开发可转移到加拿大工业的新型磨削技术，以提高生产率、可靠性和质量的磨削过程。 例如，通过将新的冷却液输送技术应用于磨削过程，我的研究使加拿大一家航空航天公司显着提高了生产率。 最近，我的研究小组发现，在平面（非轮廓）砂轮表面刻出螺旋形凹槽可以进一步提高磨削生产率，使去除的材料多出 120%，同时仍保持高质量的工件光洁度。 我们还开发了相应的创新且实用的砂轮开槽系统，可以轻松改装到现有磨床（包括手动和计算机数控磨床）上，使其可以轻松转移到加拿大工业。****拟议的具体目标我的研究是在我成功的平面（非轮廓）砂轮开槽研究的基础上，通过使轮廓磨轮能够开槽。 仿形磨削可以将复杂的形状加工成非常坚硬的材料，例如超级合金、高碳钢和陶瓷。 轮廓砂轮开槽的能力将使开槽的切实好处能够应用于更广泛的工业磨削应用，包括喷气发动机转子和叶片、齿轮、轴承滚道、钻头和刀具。****的主要成果拟议的研究目标是：***1。创新实用的仿形砂轮切槽解决方案***2。相应的磨削计算机模拟器，可以确定平面砂轮和最终成型砂轮的最佳砂轮开槽几何形状、重新开槽间隔和工艺参数****我在该领域拥有良好的成功记录和拟议的砂轮开槽研究将继续为磨削技术的进步做出重大贡献，并将通过培训该精密加工工艺的高素质人员来建立和发展加拿大的专业知识。 **
