Surface Quality of Textured Surface on Cylindrical Inner Surface using Whirling Electrical Discharge Texturing
Whirling Electrical Discharge Texturing (WEDT) was developed to create microstructures.It was thought that textured surface with low surface roughness could reduce friction coefficient on the sliding parts.In this research,surface quality was studied to evaluate the quality of WEDT textured surface.Surface quality was evaluated in terms of the surface roughness and surface integrity which were characterized by microstructure,composition and residual stress of the textured surface.The value of Rp and Rv of textured surface after finishing with improved finishing method were obtained as expected for low surface roughness to reduce friction coefficient.In addition,it was clarified that microstructure and composition of textured surface after texturing with WEDT and finishing with lapping-film depend on feed speed.Furthermore,the compressive residual stress was presented on WEDT textured surface and depended on feed speed.It was confirmed that good surface quality of textured surface could be obtained by WEDT.
