of the experimental conditions. In ECM, when the machining depth increases, structures taper. A disc-type electrode is introduced to reduce the tapering[21]. However, the major difficulty of electrochemical...: 299-313. [18] JAIN V K, NANDA V N. Analysis of taper produced in size zone during ECD [J]. Precision Engineering, 1986, 8: 27-33.

with different dimensions (up to 75 μm in length, and 8 μm in thickness) in Fig.3(a). The four legs on each unit taper down in size along their length-wise direction away from their central part, and this is in agreement with the published results[1,13]. Some units taper into wires (marked with arrows in Fig.3(a)) at the tips of their legs. These legs are hexagonally shaped. This can be clearly......
of tool design. PEI and PRABHAKAR [10] designed a milling tool with a 15° taper with respect to the bottom face of the tool. This design uses the taper angle to resolve longitudinal force......
