It is known that the unevenness of the cutting depths during the cutting processes, the different physico-mechanical characteristics of the processed materials, values as well as the parameters variation of the working regimes can lead a wear more or less pronounced of the used cutting tools.
The lubricant presence in the cutting area may contribute to the friction and thermal field values reduction, affecting the wear processes.
It can be said therefore that, the tools durability is influenced by all these factors, which requires decisions and actions to reduce the tools or/and the cutting inserts wear processes.
Introduction During the cutting process the tool wears out, due to the high contact pressures, to the high temperatures, to the relative velocities and shocks between the contact surfaces tool-part, but also due to the mechanical and thermal stressess which appears on the tool active faces, having as effect the cutting capacity loss and the processing quality diminishing.
It is mentioned as being the most rough the TiCN, Al2O3 is the most inert from chemical point of view, and the TiN is a material whose characteristics combines advantageous the properties of the other two.

Introduction Grain size is undoubtedly the most well established factor affecting impact toughness and the ductile-brittle transition temperatures (T27J, T28J, T50, FATT50%...).
Knowledge of the toughness properties and how they evolve in the ductile-brittle transition temperature region is essential for safe structural design.
Consideration of the influence of microstructural and mechanical factors on TT reveals the dynamic reference toughness (KId-ref., Eq. 1) and the area fraction of {100} planes close to the fracture plane to be significant parameters.

Out of these options, GFRP wraps have become more important because of their superior mechanical properties, effortless application, and cost-effectiveness [5] [6].
In a different study, Dyer et. al. [8] examined the mechanical properties of composites are strongly influenced by fiber orientation, which in turn affects their capacity to withstand different stress situations.
This research focused on the combination of fiber orientations in GFRP such as unidirectional, bidirectional, and multi-axial, influence the mechanical properties and effectiveness of the repair, impacting the pipeline's ability to withstand internal pressures.
The finding indicates that the orientation of fibers significantly influences the mechanical properties and effectiveness of the composite wrap.

The effect of experiment time on membrane characteristics such as flux and separation factor was investigated.
The neat PIM-1 membranes showed high toluene flux of 2.45 kg/m2∙h, but low separation factor of 4.
In addition, during distillation, BTX components are released into the atmosphere, which negatively affects the environment.
PIM-1 possesses high permeability, good mechanical and film-forming properties, which allows us to fabricate both dense [6, 7] and thin film composite membranes [8-10].
In work [12], it was demonstrated that during the operation of cross-linking with aluminum chloride due to the appearance of amide bonds and carboxyl groups that associate with each other and nitrile groups of the PIM-1 polymer, the chemical resistance of the membrane to toluene is increased, and the mechanical properties of the film are improved.

With the photosensitive resin as the processing material, cuboid parts and double-cantilever parts were fabricated by using a stereolithography apparatus, and the dimension shrinkage factor and the curl factor were studied.
The shrinkage factor was less than 1.00%, and the curl factor was less than 8.00%, which showed that the accuracy of the fabricated parts was high with the photosensitive resin for stereolithography.
Although SL has evolved so fast and received more and more attention in the past few years, and some critical research problems affect SL’s survival, maturation and further application.
SLA part accuracy is a direct result of the resin properties, and a low shrinkage resin that is cured possesses a high accuracy for its fabricated part.
It has now been found that the photosensitive resins of epoxy-acrylate hybrid systems can be used for stereolithography, and the photosensitive resins are distinguished by a very low viscosity, a very low shrinkage, a very low curl factor and good mechanical properties in the green state and after full curing.

Most of the properties of these parts are extremely high that they are not always easy to process using conventional techniques.
Parameters affecting the quality of micro holes which can save money and time have also been focused [4]. 2.
As the aim of the work is to produce micro features of high quality, the materials are so selected that their related properties are high.

The friction and wear mechanism of diesel engine was studied and the wear factors of diesel engine friction and wear was analyzed.
During diesel engine running-in stage, friction and wear of friction pair affected by lubrication and temperature.
So the main factors of friction pair wear is force, structure parameters and mechanical precision.
Ferrographic analysis pays an important role in tribology system wear process and analysis to study the mechanical parts, the wear failure type and wear mechanism.
The wear rate is small, stable during diesel engine early running-in stage wear increase, and little change in middle of running-in wear stage; In later period, with the extension of time, the friction pair surface fatigue damage accumulation, wear increase for material properties.Wear particle evolution images of diesel engine during running-in stage is shown in Fig. 4.

Based on the condition of comprehensively considering the nonlinear factors, such as backlash helical gear transmission, time-varying meshing stiffness and composition error, a coupled nonlinear dynamics model of the multi-DOF bending - torsion - axis - pendulum helical gear is built in this paper, and on the basis of the "piecewise linear" backlash function, getting backlash function that is fitting for helical gear transmission system meshing characteristics through high order fitting.
Introduction Gear transmission system is one of the widely used mechanical transmission devices, its mechanical behavior and performance has an important influence on the whole machine, thus, it occupies an important position in the mechanical equipment.
Due to backlash, integrated error, time-varying mesh stiffness, support gap and other factors in the gear transmission system, it leads to a gear system becoming a strong nonlinear system.
For judging and preventing various problems in the later stage of gear transmission system and the engineering practice, it has important theoretical significance to know the change of the mechanical properties.
