s: In order to increase process accuracy and decrease wear of honing wheel,it is necessary to analyze the machining parameters of honing process. The machining locus of plane-honing wheel,radial honing wheel and spiral honing wheel on workpiece,and the slippage locus of workpiece on honing wheel are studied here. Also, the concepts of process accuracy coefficient and honing wheel wear coefficient are presented here to describe the process accuracy and the wear degree of the honing wheel separately. Moreover,the correlative relationship between the machining parameters,the process accuracy and the honing wheel wear has been established,and the influence of the above-mentioned on the process accuracy has been investigated. Emphasis is given to prove the effect of the relative velocity between the honing wheel and the workpiece on the process accuracy. Through studying theoretically and effectively,the results show that,by optimizing the structure of the honing wheel and adapting the appropriate machining parameters,the machining quality woud be improved and the wheel wear would be decreased effectively.
