In the latter part of April 2023, a scientific research team in China successfully completed the country's first full-size superconducting test run for an ultra-high-speed magnetic levitation (maglev) train. Combining maglev technology with low vacuum technology, the train, which will become the ...
In general the static force relation (Frankpitt 1995) which expressed in terms of depth of cut (d, mm), cutting speed (V, mm/s), feed rate (f, mm/rev), and, coefficients describing the nonlinear relationships (κ, λ, and,γ) can be used as a first guess in error attenuation: ...
The surface veneer of the glass is shattered in a micro pattern by the intense heat of the laser. It is the preferred method for engraving acrylic, metal and particularly wood. Laser etching is amazingly accurate & can reproduce very fine artwork. Not in glass! Laser etching is ideal for l...
as long as the number of rows remains in the hundreds, the two approaches don't differ significantly in speed. When the row count enters the thousands, however, the gap grows significantly.
It involves mathematical modeling for production time of turning process, which is expressed as a function of the cutting parameters which include the cutting speed and feed rate. Then, the developed mathematical model was optimized with in some operating constraints like the maximum cutting speed, ...

where v is the cutting speed, Astakhiv demonstrated that the shear zone is a very narrow region using microstructure photos of single chip segments (Typical thickness is 0.025 mm) [28]. As shown in Fig. 5, the total cutting force dFof the element in the oblique cutting coordinate system ...
