It was found that less number of flute tends to give better roughness of PEEK.
It shows that a few number of flutes succeeded to provide a smooth flow of chip ejection and minimize the friction on cutting zone.
A 10 mm diameter and 70 mm of total length micro grain carbide rod was used as the workpiece of the cutter.

Pure copper is represented by UNS numbers C10100 to C13000 [1-2].
Microstructure of the hot rolled copper contains many small grains.
The oxide particles are much larger and fewer in number than in the as cast microstructure.

The material is comparable with typical technical materials, such as aluminium or magnesium, with regard to its specific properties with the grain [2].
From variant 3 to variant 2, the number of layers was doubled from four to eight layers, and the layer thickness was halved.
A number of further subjects are being considered within the For(s)tschritt project.

Graphene is an innovative material, with a broad range of potential applications, object of a large number of studies. [7] It is used as an additive in several types of coatings such as organic coatings and metal deposits [8-10].
Na2O + K2O + Li2O ≤ 35 TiO2 + Al2O3 ≤ 20 SrO+Sb2O3+Zn+P2O5 ≤ 10 B2O3 ≤ 5 Fig. 1 Standard frit grains used to produce the mixed torbida.
The main characteristic is the presence of porosity, typical of this kind of coating, that seems to be constant in terms of number and dimension of pores even with increasing the graphene’s weight percentage.

A variety of environmental and material design challenges coupled with component design concepts has given rise to a large number of coating deposition processes [1].
AlCl3 vapor reacted with the nickel and grains of intermetallic phase NiAl were formed according to the reaction: 2AlCl3 + 2Ni + 3H2=2AlNi + 6HCl.

According to those data presented in Figure 1, it is observed that the powder mesocarp babassu and microcrystalline cellulose showed similar grain size, once the highest percentage of particles passed through the tamis residual opening of 0.125 mm.
This result was expected because there is in the granulated an aggregation of a larger number of particles, which gives an increase in their diameters.
These results were obtained through the babassu granulated has a larger number of aggregate particles.

Among various synthesis routes, sol-gel based processes exhibit a number of advantages such as great flexibility, relatively low cost, simple preparation conditions, easy controllability [10].
When the calcination time was prolonged from 2 hours to 3 hours, the peak intensity was greatly increased because an increase in the calcination time makes grain growth and better crystallinity.

Also, the existence of an extremely great number of touch-pad devices cannot be ignored.
Predictions indicate the development of an ever growing number of technological improvements within man-computer and man-robot areas of interaction.
