After checking various aspects of the technology, the speed of grain removal can be selected so that the cutting time is as desired.
For this purpose, the following equation is used: V=np x L600 (m/min) or np=V x 600L (1) where: V = Cutting Speed (m/min) np = Number of steps per minute L = Machining stroke length (mm) · Feeding Rate Feed rate is the movement of the cutting tip of the cutting tool per one revolution of the workpiece.

Those peaks observed at low frequencies denote the electrode/electrolyte interface and grain boundary effects and those at higher frequencies represent the bulk relaxation of the chosen electrolytes.
It then levels off due to two opposite factors operating simultaneously, i.e., there is an increase in the number of charge carriers with an increasing concentration of dopant but leads to reduction in the mobility.

The structure and feature of machine frame The process mechanism of abrasive flow machine is that the workpiece with fixture is put on the worktable between higher abrasive cylinder and lower abrasive cylinder, and then piston of dynamic cylinder pushes piston of abrasive cylinder up and down, while the grains of the abrasive media cut the surface of workpiece to polish workpiece.
Equipment resonance frequency under modal analysis Model number Frequency（Hz) 1 2 3 4 75.549 192.58 233.86 246.5 Obviously, the nature frequency of the equipment is 75.594Hz, greater than the working frequency, which will not result in resonance.

In the face of new situation and new changes of the market economy, the original traditional number growth pattern of agricultural growth is unsustainable.
Implicit economic benefits embodies in increasing the grain yield, adjusting industrial structure, realizing farmland income replacement, causing persistent growth in household income(migrant workers can not solve the problem of pension, and thers is no income source in old age) The aspect of economic benefit appears the phenomenon of benefit deficiency and hysteresis.

Our previous research on zirconia-based nanomaterials using positron annihilation techniques allowed to draw the following main conclusions [1–6]: (1) In pressure-compacted nanopowders, positrons are trapped in Zr vacancy-like misfit defects, situated along grain boundaries (GB’s), or in intersections of three GB’s (triple points) equivalent in size to few-vacancy clusters. (2) A small fraction of positrons (≈10 %) was found to form Ps in many of studied nanopowders. (3) Inhibition of Ps formation was observed in zirconia materials doped with small amounts of Cr cations
Numbers denote compactisation pressure in kbar.

A pure Cu2O film can be produced at a low pressure of 0.5Pa due to the insufficient particle number and nonavailability of sufficient oxygen. 10 20 30 40 50 60 70 80 ▼ ▼ ▼ ▼ ▼ ▼ ▼ ▼ ▼ ▼ ▼ ▼ (311) (220) (200) (111) (110) Cu2O Cu2O Cu2O Cu2O Cu4O3+Cu2O 2θθθθ (degree) ▼□ □ □ □ ▼ Cu4O3 Cu2O 8sccm 7sccm 6sccm 5sccm 4sccm Fig.3 XRD patterns of copper oxides films for various oxygen flow rates.
The UV-Vis transmittance spectra of these films are composed of two absorption peaks attributed to the smaller grain size of the samples

The total number of alternating layers was six, and the total coating thickness was 2µm.
The energetic bombardment by pulsed bias allows a refinement of grain size and an increased densification of the deposited coatings [11].

Sand with grain size of 0.5mm and below was used for fine aggregate, and coarse aggregate is not used.

In comparison with the diffusion welding, TIG arc welding has a number of advantages, such as suitable for all-position welding, high weld speed, apt to adopt automation and low cost etc.
The existing of these large η phase grains will greatly reduce the bending strength of weld joint [3].

It has been reported that as the atom radius of RE is bigger than that of iron, so in the early stage of chromizing, RE would segregate at grain boundary and micro-inhomogeneities (e.g. vacancy, dislocation) of the test material, which could increase the diffusion pathway in numbers.
