Analysis of the Corner Error in WEDM

Abstract:

Article Preview

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. To minimize corner errors, the energy control strategy and the trace control strategy are presented. Especially in WEDM-HS processing, the methods improving the processing precision are given as follows: Using the over-cutting and retract program, controlling the wire-electrode tension and improving the guiding and allocation parts.
