磨头磨料粒度间隔及抛前粗糙度的确定,对加工生产率和工件表面质量有直接影响。本文在理论分析的基础上,推导出磨削加工各工步间磨块粒度合理间隔的数学表达式,并提出了适宜抛前粗糙度概念和确定途径。此二结果均有实用价值。
The determination of the abrasive grain spacing and the roughness before throwing has a direct effect on the processing productivity and the surface quality of the workpiece. Based on the theoretical analysis, this paper deduces the mathematical expression of the reasonable interval of grinding block size between grinding steps, and puts forward the concept of appropriate roughness before throwing and the way to determine it. Both of these results have practical value.
