Abstract
The micro patterning on cylindrical surface is conventionally carried out by the electrochemical machining, the chemical etching, the cutting and so on. However, there exist some problems in machining dimensional errors and tool lives. On the other hands, blasting is expected as one of micro fabrication methods and progress to apply for machining of hard and brittle materials. The purpose of this study is to develop the micro blasting technique for patterning of micro herringbone grooves on cylindrical parts. Then, machining characteristics in blasting of rotating workpieces are experimentally investigated, analyzing the stock removals, the burr heights and the groove shapes. In addition, micro herring-bone grooves are patterned on spindle surfaces by blasting and the performance of herring-bone bearing is investigated.
