Similar to conventional machining operations, micro-mechanical machining use miniaturized cutting tools to shape the surfaces of materials[15].With smaller diameter of cutting tools, micro-machining operations have lower cutting force and higher heat transfer thus reducing the heat and lowering the temperature compared to Macro-mechanical machining.
Therefore, milling force can be controlled at a low level through the selection of cutting parameters to reduce mechanical damage in bone osteons.
These characteristics may be related to the thermal and dynamic properties of cortical bone which should be researched further.
Fig. 8 Effect of feed direction on milling temperature Fig. 9 Effect of feed direction on milling force Conclusion As a result of this study, the following general conclusions can be drawn: The results indicated that the influencing factors on milling temperature were feed rate and spindle speed, while the milling force was mainly affected by spindle speed.

In fact, the non-geometric part was main factors to influence surface roughness, Chinese scholars Wang yusu [7] summed up into four parts when analyzed non-geometric factors: The tool factors, work-piece material factors, cutting parameters factors and processing factors, all these factors in turn contain key consideration parameters [8].
The cutting parameters factors mainly include cutting dosage and line spacing.
When considering the impact of the non-geometric part, such as tool factors, work-piece material factors, cutting parameters factors, thermal coupling in cutting process, plastic deformation and elastic recoil, the main factors were considered and secondary factors were ignored, here the mainly factor to consider the machined surface residual height and the elastic-plastic deformation factor in work-piece cutting layer.
Based on the molecular- mechanical friction theory, made the following assumptions: the tool was rigid body, wear in the cutting process was ignored, from the work-piece’s material properties, according to the elastic-plastic deformation theory of machined surface, got the height difference of the plastic flow of machined surface, thereby a simplified model as shown in Figure 4 was established elastic-plastic deformation of work-piece surface.

After harvest, whether or not the cane head is intact greatly affect the germination rate for the coming year [2].
Mechanical cutting to Sugarcane will lead to variety of damage forms, for this reason domestic and foreign scholars have researched on these.
This unit with the capability of plastic deformation, creep, large deflection and large strain matches the material properties of sugarcane.
So let the second cutting force, uniformly, act on the cross section which radius is cutting dept, and the uniform force, F was obtained according to the cutting force formula[6] and the optimal combination of factors[7].

It can be inferred different factors, including the initial supporting force, the strength of the bolting-grouting body and internal friction angle, influence the T.
Deformation partition ratio T depends entirely on the inherent mechanical properties of rocks and the bolting-grouting materials.
However, in this state the mechanical properties of materials have been inhibited, resulting in materials waste and the cost of the projects increasing.
From the perspective of stress, the mechanical properties of materials have been fully used, and it is the most economical status.
Rock deformation partition ratio depends entirely on the inherent mechanical properties and deformation characteristics of rocks.

The relative mechanical properties of UPR-mortar and substrate concrete for composing the specimens are: lower modular and high strength ratio.
The bond strength is influenced by various factors.
The distribution of these stresses on the interface depends on the relative mechanical properties between these two materials.
