Ultraprecision Surface Machining of Advanced Ceramics with In-process Eletrolytic Dressing

초록

Application of ceramics has grown considerably due to significant improvement in their mechanical properties such as light weight, chemical stability, super wear resistance, and electronics. Despite these characters, the use of ceramics has not increased because of poormachinability. Therefore, the method of using a metal bonded wheel was proposed. However, a metal bonded wheel is difficult to be dressed. Recently, the technology of In-Process Electrolytic Dressing has been developed to solve this problem. The purpose of this study is to determine the machining charaand pressurized weight on the workpiece. Using in-process electrolytic dressing (IED) the cteristics in terms of surface roughness was improved. In result, the in-process electrolytic dressing of metal lapping wheel speed, machining time bonded wheel is good method to obtain the efficient and ultra-precision lapping of ceramics (Al2O3).
