The residual stress of machined surface is an important factor affecting the fatigue strength of parts.
Residual stress is a very complex issue, process parameters, the tool geometry parameters, material matched and processing factors all affect the residual stress.
(2) When cutting the 45# steel, with the increase of cutting depth, the trends affecting of cutting force and cutting temperature of the WF and QF Groove cutting inserts are same, but the margin of cutting force and cutting temperature of the QF cutting inserts is larger than the WF.

Introduction Typical metal matrix composites, such as aluminum, magnesium or titanium [1,2], are materials that have many favorable mechanical properties like high strength, hardness, wear resistance and strength to weight ratio.
Experimental design Davim [1] used the method of Taguchi for three factors at three levels.
In this case the cutting time is the most significant cutting parameter affecting the multiple performance characteristics followed by feed.
The results show that cutting time is the major factor affecting the performance (48.37-69.69%), the percent contribution of feed and cutting speed are much lower (9.22-29.12% and 7.5-26.33%), respectively.
The results also show that cutting time is the major factor affecting the multiple cutting performance characteristics (48.37-69.69%).

Test batch samples tensile properties compared to a knit fabric.
The Version 1 stack proved to have the highest washing reliability and elastic properties based on test sample results.
During tensile tests, it was seen that the mesh and knit fabric on the commercial suit have contrasting elastic properties (Fig 7b).
Still, the mesh and knit fabric change the suit's elasticity by then also affecting the circuit.
These observations illustrate how unknown factors such as commercial hydrophobic coatings or specialist textile materials used in commercial products can easily interfere with the test results obtained.

The factors that influenced pattern definition include the type of electron beam (e-beam) photoresist, e-beam exposure parameter such as spot size, working distance, write field, step size, e-beam current, dosage as well as the type of developer and its developing time.
Introduction Fabricating of micro/nano structures on quartz would open several new possibilities because of its superior properties in UV transmission, piezoelectricity, can bear high temperature and extremely hard.
According to [5], the backscattered electron caused the proximity effect where the dose that a pattern feature receives is affected by electrons scattering from other feature nearby.
There are so many factors affect the during pattern definition and pattern transfer processes.

Previous studies [1] [2] show that changes in geometry, material properties and load-bearing mechanisms must be considered.
Both generalized corrosion affecting the surface of the bar and the localized pits, if present, must be considered.
Material properties Mean values of the properties are determined, for use in the models compared to the tests results.
The reduced cross-sections and material properties with the corrosion effects are used.

A universal testing machine and an impact tester were used to investigate the mechanical properties.
These are all to save production cost and enhance mechanical properties.
Also the particle size of the eggshell influenced the mechanical properties.
The composites mechanical properties of the composites were measured by tensile and impact testing.

The required calculated value are：tensile stress, shearing stress and the stress intensity factor of the basic-level crack.
The algorithm of the stress intensity factor is various.
When the road is under overload , road stress at the base crack become into concentration, and the cracks in the surface layer extended to the formation of cracks in the pavement reflection, and the road surface and ground water under the pavement of a variety of diseases, affecting the normal use of the road.
