Abstract
A slot-structured type diamond cutter is widely used as a cutting tool for cutting materials vertically in a straight line. The slot clearances promote the self-sharpening of each slot and also function as chip-pockets. These functions have the effect of reducing cutting resistance and increasing the tool life. Against this background, the application of photopolymerizable resins to the slot-structured type blade has been examined. In this paper, two types of slot-structured blade (slot-structured and slot-filled with resin structure) were proposed and experiments were performed to investigate cutting characteristics during dicing. As the result of a series of cutting tests on silicon wafers, with the slot-filled-structure resin blade, the improvement of machinability was verified.
