In the EDM of ordinary metal materials, the longer the pulse-on-time is, the higher the stock removal rate becomes.
Comparison of Removal Efficiency with General Hard Metal Materials Machining efficiency mm3/min Fig.9 Comparison of EDM efficiency with other tool materials EDM efficiency of PCD, especially the PCD composed of coarse diamond particles, is said to be extremely low in comparison with that of general metal materials.
For die steel and tungsten carbide materials, optimum EDM conditions were employed.
When US vibrations (axial) were given, machining efficiency for C-PCD increased to a similar level of that for metallic materials.
EDM efficiency for EC-PCD with axial US vibrations reaches to a value of about 3 times higher than that for the metallic materials.

Introduction Systems governed by delay-differential equations (DDEs) often arise in different fields of science and engineering.
Fractional derivatives provide an excellent instrument for the description of memory and hereditary properties of various materials and process.
However, during the last ten years or so, with the high speed development of computer science and the increasing ability of calculation, the realization of FC becomes feasible and FC was noticed and researched by more and more engineers.
FC is increasingly used to model problems in rheology, materials and mechanical systems identification, ANN, fractal and chaos, and other areas of applications.

Hexanedioic acid, PEG6000 and zinc oxide (ZnO) was chosen as raw materials,and tetrabutyl titanate as catalyst to synthesize the poly(ether ester) containing zinc (PEEM).
In This study, adipic acid, PEG6000, zinc oxide (ZnO) was used as raw materials and tetrabutyl titanate as catalyst to prepare poly (ether ester), then it reacted with polycaprolactam oligomers, and poly (ether ester amide) containing zinc was obtained (hereinafter referred to as PEEAM).
Han. curves can be used to study the viscoelasticity of PEEAM, and its correlation with temperature is concerned with materials' phase behavior .
