It is well known for its outstanding mechanical properties such as high strength and corrosion resistance, particularly at elevated temperatures.
On the other hand, Inconel 718 is also known to be one of the most difficult-to-cut materials, and the properties responsible for the poor machinability of it are as follows [1-3].
A major part of Inconel 718's strength is maintained during machining due to its high-temperature properties, resulting in a large cutting force.
The factors and levels of different cutting tools are shown in Table 4.
When machining Inconel 718 with cermet tools, cutting speed is the most influential factor that affects the surface roughness, followed by the depth of cut.

This study investigated the effects of material dynamic properties on the transmission of vibration to the palm of the hand and to the fingers.
Because the transmissibility of a glove depends on the dynamic response of the hand, factors that affect the dynamic response of the hand affect the transmissibility of materials to the hand.
The dynamic properties of a glove also affect the transmissibility of a material to the palm of the hand [8, 11, 13, 15].
The effects of material dynamic properties on the transmission of vibration to the finger have yet to be investigated.

Different content in the iron and steel affect the material mechanical properties, process performance and physical and chemical properties.Ferroalloy is composed of iron and a certain amount of other metal elements.
Its content can directly affect scalability, flexibility and a number of physical processing properties of the alloy.
However, in the production of low carbon or lower carbon ferroalloy, there are small scope of the carbon content control and many factors affecting adding carbon.
At the same time, it should be considered that In all the elements within calibration in the sample content are equal, This element and analysis element have similar of melting the boiling point, atomic number, physicochemical property and close to ionization potential.

Industrial dust emissions is one of the main factors of cause air pollution [1].
Determining the distance between the filter bag hole is the mainly content in the design of filter plate, which in relation to the length of the filter bag, the diameter of the bag, filtration velocity, dust properties and other factors.
But if holes arranged depopulation, it will increase the size of the equipment, increase production costs, affecting the transport of equipment, installation and waste of materials.
But they don't bear loads, it just to meet on the process and some properties of some special requirements, so to simplify handling, these structures should not be consider [4].
Counting up displacements, stresses and safety factor data get Table 3-4.

According to eigenvalue buckling analysis, the research proves its stability bearing capacity and mechanics properties.
Therefore, in order to promote the development of a new frame formwork support and have a full understanding of mechanical properties, which is necessary for the systematic and scientific theoretical analysis.

If the acting load {P} as working load, the minimal eigenvalue λcr is called structural stability safety factor, related to load.
The frame bearing capacity is mainly affected by the pole, and the maximum stress value appears at the bottom of the pole, as the basic unit.
