Analysis of the Corner Error in WEDM

Applied Mechanics and Materials, 2010
This paper introduced some current researches on the corner error in WEDM and put forward the factors that have an influence on the corner error. The deflection of the wire-electrode that has been caused by discharge force, feeding directions of the wire-electrode and radial flops of the guide pulley was analyzed in detail.

Entrance mark control on precision WEDM

Journal of Materials Processing Technology, 2004
Abstract 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.

Application of RBF Neural Network in WEDM

Advanced Materials Research, 2012
It is difficult to build a strict mathematical model for WEDM due to the complication of the machining process and the nonlinear relation between process parameters and process targets. The neural network is suited to the modeling of complex system, because it has the functions of self-organized, self-learning and associative memory, and properties of ...
