Grinding is one of the most essential and costly manufacturing processes accounting for between 20 to 25% of the total machining expenditures in industrialized countries. Creep-feed grinding is of strategic importance to the Canadian economy and it is critical to automotive and aerospace industries to produce high-precision complex profiles in components such as turbine blades and to cut profiles in extremely hard materials. The applicant has already applied new grinding techniques to the aerospace industry making significant improvements to the creep-feed grinding process with conventional aluminum oxide abrasives. The proposed research program will further develop Canadian expertise in creep-feed grinding with Cubic Boron Nitride (CBN) superabrasives and improve the productivity and quality of this precision machining process.

研磨是最重要，最昂贵的制造过程之一，占工业化国家总加工支出的20％至25％。 蠕变喂食对加拿大经济具有战略意义，对于汽车和航空航天行业来说，在涡轮刀片等组件中产生高精度的复杂剖面以及在极其硬的材料中削减轮廓至关重要。 申请人已经将新的研磨技术应用于航空航天行业，通过传统的氧化铝磨料对蠕变喂养的研磨工艺进行了重大改进。 拟议的研究计划将进一步发展加拿大的专业知识，以用立方体氮化硼（CBN）超级刺激性蠕变磨碎，并提高此精确加工过程的生产率和质量。
