Wire electrical discharge machining (WEDM) is a material removal process of electrically conductive materials by the thermo-electric source of energy .This kind of machining extensively used in machining of materials with highly precision productivity.
In order to optimize machining conditions for materials with different thermal properties or advanced materials, experimental investigations are still essential.

The tiffany in the previous Qing Dynasty was widely used not only to produce suits, sheets and hats but also to be materials for painting and writing.
There are three materials, among the unearthed the Chu embroidery, that used to be backing materials besides tiffany.
According to historical records and archaeological discovery, the Chu people uses respectively stone dyed tech and grass dyed tech to dye different silk materials.
Embroidery work needs to be painted with the design on the backing materials before stitching.
The lockstitch among the stitch technologies takes multi-row stitches to cover the backing materials completely so that the block surface can reach more than 20 rows.

The experiment results indicate that the crystal structure of the samples is fcc structure as same as that of the bulk materials.
