Entrance mark control on precision WEDM
Journal of Materials Processing Technology, 2004Abstract A tiny hollow space on the interface between the approach and the machining path may cause critical damage during superfine machining by wire-cut electrical discharge machine (WEDM). This paper points out that this space is caused by the reduction of the machined volume near the approach point.

Large taper mechanism of HS-WEDM
The International Journal of Advanced Manufacturing Technology, 2016Large 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 ...
