单颗磨粒切厚均匀化实现脆性材料延性域磨削技术
Ductile Regime Grinding of Brittle Material with Unifying Undeformed Chip Thickness of Grain Cutting Edge
摘要
Abstract
In grinding of brittle materials, it is easy to produce quality problem such as surface/subsurface damage during machining and the machining efficiency is low. This can be a bottleneck of the commercial mass production of brittle materials. The paper proposes a new process principle, which uses the grinding tool with orderly distributed grains and precision dressing to unify the undeformed chip thickness. From this method, every grain can be made suitable for ductile cutting, then the ductile grinding can be realized. Accordingly, the paper produces monolayer brazed super abrasive grinding tools, and conducts a series of experiment including dressing and grinding. Finally, a ductile surface of Zirconia ceramic is achieved. The experiment proves that this process principle is liable, effective and operable.关键词
