Based on machine kinematics and cutting theories, the simulating method for the generation of three-dimensional surfaces in face turning and flycutting of SPDT is studied.
Material removal by machining involves interaction of five elements: the cutting tool, the toolholding and guiding device, the workholder, the workpiece, and the machine.
The residual stress formed on the surface of rolling bearing in superfinish hard turning will influence the fatigue life of rolling contacting after stress decay.
The cutters used in high speed machining(HSM) have poor rigidity, therefore the method fits to HSM of die cavity due to the unfluctuating cutting force characteristic.
This paper shows that under certain conditons it is possible to diminish and even eliminate the nonlinear distorsion of a peak envelope detector by biasing the diode adequately.
To hit a good drop shot one needs a good slice or underspin shot.A drop shot is really nothing more than an underspin shot that lands short or close to the net.
Glaciers may form in permanently cold areas, and these slowly moving masses of ice cut out valleys, carrying with them huge quantities of eroded rock debris.
A study of experienced golfers revealed that those who hit chip shots while focused on the flight of the ball performed significantly better than those who focused on the motion of their arms.
By warming and kneading, cutting and twisting, dismembering and re-joining the incipient image she had in about a quarter of an hour produced a shape which tolerably well resembled a woman, and was about six inches high.
The most popular laser eye surgery uses lasers to cut in and reshape a patient's eye, while the specific type of operation that Li underwent due to her high myopia involves implanting an artificial lens inside the eye.
