Conclusion. In this paper a new application for micro-EDM was presented. The use of the WEDG for the production of milling tools has several advantages. The geometry can be changed quite easily and the potential of scaling down the size of the milling tools is very high. In comparison to other contactless machining technologies the Micro-milling is a mechanical machining process that uses miniature tools rotating at extremely high speeds to remove unwanted material from a workpiece’s surface. This way, the cutting tool removes unwanted material from the surface of a rotating workpiece, producing 3D features on a micro-scale. 7.

Section snippets Applications of micro tools. Due to miniaturization trend, there is an increased demand in fabrication of micro components. Examples of these kind of micro-features could be micro holes for fiber optics, biomedical filter, micro nozzles used in jet engines, micro mould/die either for micro optics or micro-fluidic devices [28].Channels, through holes, and chambers are frequent examples of the application of micro-milling [36,37,38]. Micro-milling has many appealing characteristics—it can easily manufacture 3D structures of high aspect ratios with inclined angles on side walls, which have beneficial importance for demoulding [13,15].

contour milling, shallow slotting, contour milling and pocketing applications. Flutes Spiral-shaped cutting edges are cut into the side of the end mill to provide a path for chips to escape when an end mill is down in a slot or a pocket. The most common options are 2, 3, or 4 flutes. The more flutes, the more cutting edges but theThe limitations of significant tool wear and tool breakage of commercially available fluted micro-end mill tools often lead to ineffective and inefficient manufacturing, while surface quality and geometric dimensions remain unacceptably poor. This is especially true for machining of difficult-to-machine (DTM) materials, such as super alloys and Optimal tool design in micro-milling of difficult-to-machine
