Custom Micro Tooling for Mechanical Ductile-mode Micro/nano Machining of Hard and Brittle Materials X.
One of the key factors affecting successfully ductile-mode machining is micro tooling.
Among mechanical micro/nano machining processes, micro/nano milling is the most flexible one to create three dimension (3D) features for applications such as micro-electro-mechanical systems (MEMS) and the die/moulds for very high accuracy glass products.
Therefore, custom micro tooling is a necessary to provide micro tools with various tool geometries according to the workpiece material properties and workpiece geometries aiming at high accuracy, high productivity, and high surface finish achieved by ductile-mode machining.

Influencing Factors of Phytic Acid Conversion Coating on AZ91 Magnesium Alloy Yanling Lu a , Yankun Chen b, Shiguo Du, Yi Guo, Qing Hong Mechanical Engineering College, Shijiazhuang, Hebei, 050003, China aLuylrp01@yahoo.com.cn, bcyk19860110@163.com Key words: magnesium alloy; phytic acid; conversion coating; corrosion resistance Abstract.
But development and application[3-5] of magnesium alloy are limited to a large extent since chemical properties of magnesium alloy are too active, and its corrosion resistance is quite poor.
Result and discussion Importance of phytic acid conversion coating influence factors Known from the above documents, the major factors affecting the phytic acid conversion coating forming include conversion solution pH value, concentration of phytic acid, coating forming time and temperature.

It is shown by the orthogonal experiments that the order of importance of the four factors affecting the corrosion resistance is conversion solution pH value> concentration of phytic acid >coating forming time > coating forming temperature.

The main factors and factors interaction that affected to surface finish were investigated.
Because of carbon composition between 0.4-0.8 % that it can be improved property especially hardness of material for proper use to mechanical part and cutting tools.
In previous study, factors of milling can be affected to quality of surface such as feed, speed, depth of cut, cutting tool, mechanical load, thermal load, and abrasive load.
It means that both of factors was affected to surface roughness.
However, ANOVA showed that depth of cut could be affecting to surface roughness.

Abstract Hardness measurements can simple, but very useful provide materials mechanical properties.
This is a test that is extremely localized in volume and does not affect significantly the structural properties.
This steel is used for its properties primarily for welded structures as basic material.

The end surface angle of workpece is one of key factors that affect burr sizes and shapes.
Recently years, foreign engineers and scholars of mechanical engineering attach more and more importance to the mechanism of burr formation, influence factors, the controlling method, deburring technology and others[1,2,3].The formation of burr is a complicated process.
There are many factors affect burr shapes and sizes , but the support rigidity of the end face of workpiece is a main factor which affects negative shear angle and shear strain，furthermore, affects burr shapes and sizes.
It has very high strength and favorable machinability But the burr/fracture directly affects the edge quality of workpiece, it is very necessary to study the mechanisms of burr/fracture formation and effect factors systematically in order to gain better edge quality in high-speed machining.
Conclusion The end surface angle is one of key factors that affect burr shapes and sizes, In this paper, a finite element method of a metal-cutting process including burr/fracture formation has been presented.

CFD (Computational Fluid Dynamics) software was applied to analyze the major influencing factors of the robot’s mechanical properties.
Combining these simulation data with the derivation process of Resistive Force Theory, the models for the mechanical properties simulation of the swimming robot were revised, and the explicit empirical formula of propulsive force is obtained.
Therefore, in this paper, a series of parameters which impact on the propulsion including the helix tail's structure and operating environment factors are simulated with Fluent.
Simulation results show that, the thrust produced by the rectangular cross-section one is 30% larger than the circular cross-section one when all other factors are the same.
This figure shows that, μ affects both and T// .

This paper deals with mechanical properties of PVA/halloysite nanocomposite films which were fabricated by a casting method.
Thus we attempted to improve the mechanical properties of PVA by adding halloysite, which has a large specific surface area.
One of the affecting factors causing this result would be the adhesion of the interface between polymer matrix and fillers.
