Especially ultra-short pulse durations confine effectively electrochemical reactions used for etching the material to a very small region in close proximity to the tool electrode [4] .
Under the circumstances of ultra-short pulsed micro-ECM, the time constant τ is very small, machining current density is very large within machining area of work-pieces, so the considerable amount of work-pieces material is removed.

Introduction The input parameters of a structure, like geometry, material parameters and loading, are expected to vary.
Both material, νF, geometrical, νG, and model, νM, uncertainties could be evaluated through the use of appropriate coefficients
(4) Schlune’s and Cervenka’s methods differ in evaluating the coefficient of variation (COV) of the materials.

Part level feature includes general feature and material feature.
Material feature is the description of the materials used for the blade part.
The attribute of general feature is composed of part name, part code, material mark, blade categories, blank categories, part overall dimension, part weight, production categories, technical requirements, designer and other information. 2) Material Feature Material Feature refers to the information aggregate of blade material performance (such as material trademark, material feature, the main body tissue of the materials that is used for blade, material varieties and specification), heat treatment mode and surface treatment methods, and so on.

Brittle materials, as quasicrystals, ceramics and many semiconductors, are often completely destroyed when stress and strain in uniaxial deformation exceed the elastic limit.
This missing of an Indentation Size Effect seems to be a feature of indents into materials exhibiting phase transformations during indentation.
