“…At present, there are few reports about machining nickel thin-walled workpiece with WEDM. In our experiments, the stable parameters used for machining nickel plate with 0.6mm thickness are obtained based on the parameters cutting steel plate with 3mm thickness by adjusting the following parameters: servo voltage (VG), peak current (IP, SA) and liquid pressure (LQ), pulse interval (SB) and cutting speed (FA) [10] . The parameters are listed in Table.…”

Fuze Micro-Electro-Mechanical System (MEMS) has become a popular subject in recent years. Studies have been done for the application of MEMS-based fuze safety and arm devices. The existing researches mainly focused on reducing the cost and volume of the fuze safety device. The reduction in volume allows more payloads and, thus, makes small-caliber rounds more effective and the weapon system more affordable. At present, MEMS-based fuze safety devices are fabricated mainly by using deep reactive ion etching (DRIE) or LIGA technology, and the fabrication process research on the fuze MEMS safety device is in the exploring stage. In this paper, a new trans-scale fabrication method of metal-based fuze MEMS safety device is presented based on UV-LIGA technology and the micro Wire-cut Electrical Discharge Machining (WEDM). The method consists of fabrication of micro-spring by UV-LIGA technology, the fabrication of mesoscale structure by WEDM, the micro assembly of micro spring and mesoscale structure. Because UV-LIGA technology and WEDM technology were introduced, the production cycle was shortened and the cost was reduced. The overall dimension of the micro-fuse safety device is 9.5×12.3×0.6 mm and the smallest dimension is 10μm. Besides, four problems in the fabrication process have been solved effectively, which is helpful for the fabrication of similar kinds of micro devices. The fabrication method presented in this paper provides a new option for the development of MEMS fuze.

“…WEDM (wire-cut electrical discharge machining) with its features of non-contact, high cost performance, suitable for single-part or small-lot production, has a unique advantage in the 2D contour processing. Although some scholars [4][5][6][7][8][9][10][11][12] had done a lot of research work in this aspect, more perfect processing methods are lacked on metal components with micro/meso scale, and the defects, such as the distortion of cantilever and the bend of sharp corners, are prone to appear.…”

In order to meet the machining demand of the metal components with micro/meso-scale, a kind of micro-fabrication method is explored by Wire-cut Electric Discharge Machining (WEDM). To find solutions for the problems of machining, a series of WEDM experiments for the micro/meso-scale structure of a thin nickel plate are carried out based on the analysis of technology regularity of WEDM. Experimental results indicate that the reasonable constraint on the discharge energy is the key to finish the machining of the metal components with micro/meso-scale. The stable machining can be achieved by adjusting discharge parameters to lower levels. The micro/meso-scale machining defects of cantilever distortion and sharp corners bending can be solved by segmented and multiple cutting accordingly. At last, some examples of complex structures machined are shown.
