To reach high surface integrity and processing efficiency, the semi-fixed abrasive wheel (SFAW) is developed. Compacting process plays key role in adjusting the structure and machining ability of SFAW. In this paper, the manufacturing of SFAW is introduced, and the effect of compacting patterns and process parameters on the structure of SFAW is discussed with experimental results and a developed model based on particle flow method. It is found that the lower compacting velocity result into longer time to achieve a certain compacting force. It needs greater compacting force to achieve a certain compacting density with higher compacting force loading rate. The higher friction factor and contact module of grits result into greater compacting force to achieve a certain compacting density.
