Application of Computer Simulation Technology in the Analysis for Gilling Machine Structure Lijiao Pan1,a, Zitang Yu1,Yongming He1 1 Yiwu Industrial and Commercial College, School of Electro-mechanical and Information Technology, Yiwu, 322000, China; apanlijiao216@163.com Keywords: Computer simulation technology, Gilling machine, Prestress, Modal analysis Abstract.
It provides some suggestions that can be used to research the effect factors of gilling machine design, the gilling machine structure optimization and operating mode control.
The computer simulation technology can not only employ to analyze product structure and thermo-physical accurately, and provide some visual simulation results, but also can optimize structure parameters and the structure properties by simulation software.
So working-screw is one of main working parts, its dynamic-state and static-state characteristics affect the performance of the whole machine, and the structure dynamics analysis and static mechanics analysis are very necessary.
Hence it is necessary to deal with the assembly without affecting the analysis.

Therefore, melt pool is an important behavior that affects the final quality of track formation.
However, the main bottleneck is accuracy and appropriate material properties that give the best end product in terms of mechanical properties that comparable to bulk material.
Critical factors in AM since from the beginning are material capability, accuracy and surface finish.
Hence, metal powders quality and substrate surface were affected.
During this, melt pool was formed, which affect the overall part quality. 2.

Composites have a wide range of applications in robotics, aerospace, aviation, and automotives as they have desirable properties such as high strength to weight ratio, good mechanical and electrical properties, and durability.
Matrices resist the environment attacks to the composites and have a major influence on many mechanical properties of a composite[11, 21, 22].
One of the important factors to calculate strength of a composite is to measure the relative volume and weight ratios of the composite.
The properties of the composites are affected by the voids present in them and knowledge of void content in a particular composite is essential to determine its overall properties[35].

Such excellent properties rely on their high additions of chromium, nickel, molybdenum, copper and other alloying elements in austenite along with low carbon contents, which generally causes the balance amount of iron to be less than 50% of the total in the alloys [4].
There are many factors that affect the load values during the hot working process, such as the flow stress, the geometry of deformation and the friction at tool work-piece interface [7].
Among them, the flow stress of the material is the main factor.
Hot compression tests were conducted on a Gleeble1500D thermal–mechanical simulator with cylindrical specimens of 8 mm in diameter and 12 mm in length over the temperature range from 1000 to 1200°C, strain rate from 0.01 to 10s–1.

Recently, MGCs with in-situ dendrite-phase have attracted much attention for their promising properties combining the high-strength and toughness.
The wettability and interface reactivity are of great significance on the quality of bonding between the constituents and further affect the final properties of the composite material.
As is known, wetting of metal by a liquid is a complex phenomenon sensitive to large number of factors such as substrate surface roughness, heterogeneity of the surface, atmosphere, temperature and interface reaction[13].

However, further research is needed because the effects of the reinforcement on properties of the composite are still not comprehensive, and greatly affected by the additives and parameters of sintering process.

Introduction Classifiers are the key equipments in closed-circuit grinding systems, the performance of the classifier will directly affect the technical and the commercial factors of a powder grinding system, and played a decisive role in the quality standard of the grinded powder products, therefore the designing parameters of the internal structures of a classifier is crucial in helping to increase the efficiency of the separating process under certain circulating load.
The animated presentations and photos demonstrate the cyclone classifier’s structures and properties.

Further, Polyimides (PIs) also have extraordinary properties of high thermal conductivity, high electrical resistivity, chemical inertness and excellent mechanical properties [67].
One of the important factors that determine the reliability of ODA-GO is the polymer interaction that binds the GO and the polymer together in a mat form.
Factors that influence the dielectric constant such as anions, solvents and organic linkers were also studied.
Interaction of the low-k material with CNT sidewalls is a major area of concern as the thermo mechanical properties of the low-k material affect the performance of CNT interconnects.

Hybrid Non Conventional Machining of Glass - A Review Nagaraj Y.1,a*, Jagannatha N.2,b and Sathisha N.3,c 1Research Scholar, Department of Mechanical Engineering, SJMIT, Chitradurga, Karnataka, India 2Professor, Department of Mechanical Engineering, SJMIT, Chitradurga, Karnataka, India 3Professor, Department of Mechanical Engineering, YIT, Moodabidri, Mangalore Karnataka, India anyk6426@gmail.com, bjagan_nath05@rediffmail.com csathishan20@rediffmail.com Keywords: non conventional machining, material removal rate, heat affected zone, surface finish, tool wear Abstract.
Advance machining techniques are developed to fabricate hard to machine materials with excellent material properties.Traditional machining of such materials creates high cutting forces that, in some cases may not be maintained by the workpiece.
Jagannatha et al. [15] performed the machining on glass by combining abrasives with hot air jet to study the material removal rate and surface roughness using one factor at a time approach.
Decrease in the mechanical strength and increase in the machinability was observed.
The mechanical properties at the interface was approximately same as that of base materials.
