For axial load and hole exit quality, cutting edge types, clearance angle and second point angle were primary factors, and first point angle was secondary.

At the same time, the depth of micro-cutting and the increment of elastic and temperature deformations affect the values of the radial wear of the tool and the radial removal of the material.
Each of the subsystems has its own set of properties, state parameters, development history, vector of input and output variables, and vector of disturbing effects.
Changes in the cutting mode affect the maximum depth of micro-cutting.
Changes in the radial removal of metal, the wear of the wheel, the increments of elastic deformations and the depth of micro-cutting during one cycle during internal cylindrical grinding Conclusion Thus, a description shows that to predict the spatial position of elements of the technological system it’s necessary to have information about the quality parameters of the workpiece, the original profile of the tool and analytical models that define the relationship with the technological factors the depths of micro-cutting, radial, material removal, wear of the wheel, cutting forces, elastic and thermal strains.

Introduction Concrete cracks not only affect the bearing capacity of structure, but affect its durability greatly.
To spread and apply this Cemfiber well at home, the paper does experimental research on the properties of cracking resistance of Cemfiber.
The main physical mechanical properties of DF fiber and Cemfiber are shown in Table1 and Table 2 respectively.
The properties of cracking resistance of reinforced mortar improve lineally with the increasing of the content of Cemfiber.
Many factors may add the shrinkage and lead to crack, such as high cement or water content, due to the increase of the amount and the tensile stress of the capillary.

Determining these values by torsional vibrations is based on measuring the vibration factor δ.
The relaxation time of the structure and stabilization of the properties can be recommended as the value of τtreat.
The best service properties of ribbons were obtained in the third regime.
The physical properties versus the annealing temperature are shown in Table 1.
The model being beneficial is attributed to its retaining information on the actual connection between the liquid and solid states, and implies the possibility to forecast the results of physical-mechanical impacts on the melt, affecting the final product properties.

Introduction Surface structure was identified as one of crucial factors particularly important for bone implant.
As preliminary knowledge, wettability and surface roughness affect cell response synergistically even though how to affect is not explicit[1].
Our previous work showed that nano structured TiO2 had excellent properties of proteins adsorption and cytocompatibility, as well as innovative application in cell sheet technology[9].
Wettability is one of most important factors that dominate cell response to the surface of materials.
As an interface between substrate and adhesive cells, mechanical stability of films is significant requirement.
