| Research Abstract |
To realize the optimization of tribological properties in microforming by designing the surface texture on microforming die, which is under the complex contact conditions, the present study aims to clarify the relevance between the dimensions of micro surface texture and friction and wear properties under the specific contact condition in microforming. Through the investigation, it was found that the main contribution of the surface texturing under dry sliding friction were the enhancement of the wear debris ejection. Based on this result, it was demonstrated that the surface texturing dimensions of its gaps and width could be designed corresponding to the variation of contact length and surface pressure during the microforming process.
