Large taper mechanism of HS-WEDM

The International Journal of Advanced Manufacturing Technology, 2016
Large taper (≥ ± 5°) high-speed wire electrical discharge machining can be affected by many factors. The positioning error of wire electrode caused by guide wheels and the run-out of guide wheels are particularly important. Moreover, dielectric fluid cannot wrap the wire electrode appropriately and flow into the machining region along with the wire ...

Material Removal in WEDM of PCD Blanks

Journal of Engineering for Industry, 1994
Polycrystalline diamond (PCD) tools are now widely used in machining a large variety of advanced materials. However, the manufacture of PCD tool blanks is not an economical and efficient process. The shaping of PCD blanks with conventional machining methods (such as grinding), is a long, labor-intensive and costly process.

Research on Corner Control Strategy of the WEDM

Applied Mechanics and Materials, 2014
Corner machining accuracy has always been one of the important properties of WEDM. In this paper, the reasons for the corner error of the WEDM were discussed. Then the mathematical deflection model of the electrode wire was established. By experimental measurements, the kerf width and the deflection of the electrode wire were obtained.
