Creep-feed grinding with superabrasives

磨削是最基本和最昂贵的制造工艺之一，占工业化国家机械加工总支出的20%至25%。蠕变进给磨削对加拿大经济具有重要的战略意义，对于汽车和航空航天工业来说，在涡轮叶片等部件中生产高精度复杂型材以及在极硬材料中切割型材至关重要。申请人已经将新的磨削技术应用于航空航天工业，对传统氧化铝磨料的蠕变进给磨削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在立方氮化硼（CBN）超磨料蠕变进给磨削方面的专业知识，并提高这种精密加工过程的生产率和质量。

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.
