Abstract
Micro-EDM (micro electro-discharge machining) integrated with Nd-YAG laser as a novel process for precise micro-assembly is presented in the paper. In the integrated system the individual micro-parts assembled can be machined using micro-EDM, and accurately moved to the desired position using ultra-precision motion control, and fuse bonded with a laser beam. This process is demonstrated through two cases of a precise endless diamond wire saw defined as a pin-to-pin and a pin-to-plate micro-mould using the novel integrated system. As a result of this on-line assembly process, the pin-plate positioning accuracy and perpendicularity can be maintained, and a smooth pin-pin joint can also be obtained.
