A study on the micro tooling for micro/nano milling

The design and optimization of micro polycrystalline diamond ball end mill for repairing micro-defects on the surface of KDP crystal

“…In order to analyze how geometrical parameters of tool influence the cutting process, the micro ball end mills with different geometrical parameters should be carried out. However, the rake angle cannot change from 0 • to −70 • only for one type micro ball end mill, what is more, the symmetrical tool geometry was recommended by Cheng et al [11], therefore two types doubled-edged micro ball end mill, namely Type I and Type II, were designed by also considering high stiffness of micro end mill, and avoiding unnecessary contact between the micro end mill and machined surface of workpiece. Type I, as shown in Fig.…”

“…Cheng et al [11] proposed the design criteria and the corresponding design process of micro milling tools, where the symmetrical geometry of tool was preferred due to the good balance under very high rotation speed. They [12,13] also designed micro ball end mills for the machining of hard and brittle materials, and the geometrical parameters of mills were optimized using FE method.…”

U-Line

“…The research is continuously trying to improve the USM mills, because the tool geometries have a direct impact on the final machining quality (Cheng et al 2011). The first-produced USM mills were made by downscaling the milling tools known from conventional machining (see Fig.…”

Edge fabrication and process optimization of precision woodworking PCD millers with disk electrical discharge machining

“…Although it has been shown that these three methods are versatile for machining difficult-to-work materials, low machining efficiency is one of their main disadvantages. How to increase eroding speed, reduce the wear of electrode and maintain reasonable accuracy at the same time has always been the topic of EDM [11][12][13][14][15][16]. As for fabricating PCD tools, the aforementioned studies mainly focus on the methods of using the Sinker EDM and the Wire EDM [12,14,[17][18][19][20][21][22][23][24][25].…”
