Milling Stability Lobe Diagram Construction on FV520B Stainless Steel and Experimental Testing Investigation Hongkun Li 1.a and Pengshi Zhao1.b 1School of Mechanical Engineering, Dalian University of Technology, Dalian, 116023, China alihk@dlut.edu.cn,bzhaops1991@163.com Keywords: FV520B; Milling chatter; Stability lobes; Experimental verification Abstract.
Because of well mechanical properties, the FV520B steel can meet the requirements.
It will seriously affect the milling efficiency and reduce the machining accuracy, wear off the tool, and even destroy the machine.
Milling force experiment needs to consider three factors (n, ap and f).
By orthogonal experiment theory, we took three different values ​​of each factor and designed the milling parameters.

Wettability of solid surfaces is one of very important properties, which is governed by both the interface energy and the microstructures.
The hydrophobic or hydrophilic property of solid surface all can be progressed by roughness.
Then the Eq.3 is obtained by the introduction of roughness factor to Eq.4.
Therefore, for the Wenzel model surface, the microstructures can improve the hydrophobic or hydrophilic properties of solid surfaces.

Duo to quality defects of welds and some other factors，stress concentration is critical in the typical beam-column welded connection.[7] So the brittle failure of the welds at the beam-column connections can happen more easily, which lead to the damage of steel frame.
In the paper，finite element models are established by using numerical methods to study the mechanical behavior of these kinds of connections.
The impact produced by design parameters Lb on the mechanical properties of the nodes is not apparent.
So properly raising the widened flange arc length may play a role on the mechanical property in some extent.
Widened beam flange width bwf mainly affects the stress values of beam surface near the column flange.

These alloys are recognized to be highly cost effective and combine good corrosion properties and formability with moderate strength.
The last two properties are mainly controlled by the grain structure/size in the material and show opposite trends with increasing grain size: mechanical strength decreases whereas the material becomes less subject to corrosion.
Depending on the targeted applications a compromise between these two properties has to be made by controlling the softening behavior.
Then the interfacial concentrations must fulfill the following solubility products [4]: (4) The is the Gibbs-Thomson factor that describes the influence of precipitate curvature on interfacial concentrations.
The grain size, however, is barely not affected in these particular cases, as site saturation is assumed and concurrent precipitation only influence growth.

Because it is known that the direction of void growth is different due to applied stress and/or strain distribution in general, the void growth law must have the anisotropic property.
Fig.3 Relation between damage tensor and local strain for shape factor L2/L1 = 1.
Figures 4 and 5 show the results of shape factor L2/L1=4/3 and 3/2, respectively.
Fig. 5 Relation between damage tensor and local strain for shape factor L2/L1 = 3/2.
Conclusion The validity of the proposed anisotropic void growth model was investigated under the uniaxial tensile test of perforated sheets with several different shape factors and it was found that the proposed model can well describe the anisotropic development of void shape under uniaxial tension for both two materials SUS304 and A5052.

In order to research the influence property of pre-tightening force, centrifugal force and dynamic cutting force on cutter components, and reveal safety recession of the cutter components, this paper makes load analysis for high speed milling cutter, studies cutter deformation, joint surface crushing, ductile fracture and other damage characteristics, gets the safety recession order of cutter components by safety margin theory.

Among them, tangential force affects obviously knifepoint, radial force is a small effect on stress and deformation, axial force is the main factors of blade positioning the stress and deformation.
Tangential component of cutting force has a significant effect on knifepoint, the radial component of cutting force has lesser effect on the stress and deformation of cutter, and the axial component of cutting force is the major factor of the stress and deformation of cutter body location surface.

The efficiency of the fan has been shown to be majorly affected by dust build-up [5], noted that an adverse dust build up on the blade could affect the speed of the fan and even cause the blade to wobble as well as cause the fan’s motor to heat up, thus resulting in more power being drawn for operations as well as pose safety challenges.
The conversion of electrical energy into mechanical energy in ceiling fan is done by an electric motor [3].
The design involves mechanical and electrical analysis.
The choice of Pugh Matrix Method was based on its simplicity and various determining factors of the concepts.
Determination of the physical properties of the cleaners and accessories Due to the geometrical properties of the fan blades, the cleaner, and holders would be made bigger (in width, thickness) in dimensions to ensure effective sliding.

Near Infrared Spectroscopy (NIRS) technique was used to predict the physical-mechanical properties (HEIN et al., 2010).
Barros filho (2009) compared two process for bagasse obtaining and concluded that such factors do not significant influence the quality of panels.
However, such properties were affected by increase of candeia wood in the panels.
Opposite results were obtained for mechanical properties.

The clear distance between the shield tunnel and the railway is a decisive factor of the problem mentioned above, thus influencing the protection measures.
According to the engineering practice, the saturation coefficient includes the coefficient of consolidation caused by grouting pressure, the coefficient of soil properties based on geological condition and the coefficient of construction consumption , along with the coefficient of overexcavation aroused by tunneling method.
