Fracture onset coefficients and edge shape transition probabilities made it possible to evaluate the edge fracture characteristics of abrasive grain rationally. By grinding tests of single grain, these probabilities were determined for five materials: regular aluminum oxide, white aluminum oxide, single crystal aluminum oxide, green silicon carbide and black silicon carbide. Using these probabilities, transitions of edge shape distributions were calculated by applying the theory of Markov process to clarify the difference of abrasive materials in edge fracture. As a result, these probabilities proved to be an appropriate index for edge fracture characteristics of grinding grain materials.

A new maching method of pretreatment magnesium alloy surface was design based on abrasive belt grinding technology, which offered a kind of technology for magnesium alloy tube surface machining. Experimental results indicated that abrasive grain granularity, belt speed and workpiece feed speed play an important role in grinding for magnesium alloy tube surface, which made magnesium alloy tube surface roughness from 0.22 um to 2.93 um with 400 grade to 80 grade on abrasive grain granularity of belt, raise the belt speed to reduce surface roughness, but raise workpiece feed speed to deteriorate roughness.
