Creep-feed grinding with superabrasives

点击翻译按钮获取中文摘要

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.
