With the assistance of Taguchi quality design, ANOVA and F-test, significant parameters affecting the kerf have been identified.
Due to the inherent properties of the process, wire-EDM can easily machine complex parts and precision components out of hard conductive materials.
Nimonic alloys, however, are known for the retention of important mechanical properties, such as impact strength, yield strength, and hardness, in temperatures as high as 1100°F, depending on the grade [3].
Pilot experimentation was conducted using ‘one factor at a time approach’, to observe the trends of influence for the selected input parameters.
ANOVA results shows that pulse-off time and pulse-on time are the most significant factors with percentage contribution of 18.6% and 12.93% respectively.

Verified by testing resistance, the change rate of the wire feed speed is slightly, which proves that the new system has good mechanical properties and a stable speed.
The armature voltage negative feedback regulation having compensation effect on the fluctuation of voltage can only achieve the stability of armature voltage, without playing a regulatory role due to load changes, its mechanical properties are relatively weak.
The Basic Principle of Detecting Motor Speed [3] Wire feed system usually adopts DC motor as it has good speed regulation, large starting torque and relatively strong mechanical properties.
In the process of wire feed, the main factor which affects the speed is resistance.
It proves that the system has good mechanical properties

The mechanical properties and deformation behaviour of magnesium alloys are significantly influenced by the testing temperature, texture and grain size.
The paper gives an overview on the influence of the grain size on the mechanical properties of Mg and Mg-2Al alloys at various temperatures.
The mechanical properties and deformation behaviour of magnesium alloys are significantly influenced by the testing (service) temperature and alloying elements.
It should be mention that there are different values of ky for the same alloy subjected to different thermo-mechanical treatments.
The value of ky may be affected by the resulting textures.

Introduction In recent years ultrahigh-strength strip steels (UHSS) produced using thermomechanical rolling and direct quenching (TM-DQ) have become interesting materials for structural applications, because they can exhibit the good combinations of mechanical properties and weldability [1–3].
Mechanical Testing.
As it can be seen in Fig. 2 and Table 1, neither the surface roughness nor chemical composition change as a result of the presence or absence of red scale, which rules out these factors as possible causes of the differences in bendability or final microstructure.

Introduction The physical and mechanical properties, such as high hardness and strength at elevated temperatures, chemical stability, low friction and high wear resistance, make ceramics more attractive than other materials for many applications.
The studies mentioned above mainly focus on fatigue behavior influenced by the cyclic frequency besides many other factors/parameters.
The study shows that the size of ZrO2 crystal grain is one of the major factors affect the t-m phase transition.
When being destroyed, it induces to t-m phase transition which leads to the improvement of mechanics properties.
The prohibition effect and the improved fatigue properties are helpful to acquire high quality surface in polishing treatment.

Cryogenic treatment of cutting tool material has been reported improving properties of the materials, resulting improved performance.
The life of a cutting tool plays an important role and consequently, is a major economy factor.
So, it is always important to improve the properties of material by heat treatment method, which has better control over the range of the properties that a given material has.  
CT results in physical changes, like shrinkage and densification in the cobalt binder, which retained the carbide particles firmly and enhances the tool material properties.
This was due to improvement in properties of tool material after CT, which did not allow to wear out the cutting edge easily.

Figure 1 shows the test of rheological properties.
The viscosity of a non-Newtonian fluid is not constant at a given temperature and pressure but depends on other factors such as the rate of shear in the fluids.
The friction factors of high-concentration solutions data still far to the Virk’s line (B) according to the increase in the Reynolds number, Re.
Drag reduction is significantly affected by the type of fiber and the concentration of fiber.

Ultrasonic Transducer Design via APDL Optimization Zhang Xianghuia , Li Guihua b School of Mechanical and Electrical Engineering, North China University of Technology, Beijing, China a email: zhangxianghui1@126.com, b email: liguihuatt@163.com Keywords: ultrasonic transducer; single objective optimization; APDL optimization Abstract.
Like almost all mechanical systems, the transducers are always expected to be optimal.
However, the design of sandwich ultrasonic transducers is a difficult task, because overall characteristics of piezoelectric transducers are affected by various factors such as dimensions of every part, inherent properties of materials, etc.
Table 1 gives those parameters that affect the performance of the ultrasonic transducer.
The whole transfer matrix relation for the ultrasonic transducer is derived as follows: First, the whole transducer is conside -red as a connection of a piezoelectric stack element and three mechanical elements.

This parameter is recognized as the quality measurement of waste cooking oil that might be affecting the performance of WCO in binder modification.
The high quality of WCO affected the good performance of rheological properties where the higher rutting resistance and temperature failure at 64 0C is achieved by the modified asphalt binder with the addition of WCO in December sample.

Wear is the predominant factor affecting die life.
However, the material properties and contact conditions vary with temperature.
To predict die wear during warm extrusion where die temperature, being the dominant factor affecting wear, may rise to over 400°C, unevenly distributed, temperature-dependent effects must be considered [2].
Using finite element analysis, detailed information regarding important factors such as instantaneous temperature, pressure, and velocity of each element node, per simulation step of the die, can be acquired[5].
Conclusion (1) Extrusion temperature, extrusion speed, extrusion pressure, and lubrication conditions are the primary factors influencing mold wear
