Abstract. As rocks are transported, they primarily undergo two breakdown mechanisms: fragmentation and chipping. Fragmentation is catastrophic breakup by fracture in the bulk – either subcritical crack growth under repeated collisions, or from a single high-energy (supercritical) collision produces angular shards. Chipping distinct low-energy mechanism of impact attrition that involves shallow ...

Ultra-thin dicing blade is usually used to achieve a high precision cutting in semiconductor back-end packaging and assembly. Lots of interactional parameters involving preparation process bring difficulties qualities good working life blade. In order address these problems, this study prepared three kinds blades characterized the properties blades. It first proposed abrasive exposure coefficie...
