The result indicates the drawing force increases with the growth of the drawing velocity and the reduction ratio, whether with or without vibrations.
The dieless drawing process was feasible through precise control of process parameters such as drawing velocity, temperature and rates of both heating and cooling.
The influences of the die angle, reduction, aspect ratio of the die, interfacial friction and drawing velocity on the die geometry are studied.
In tapping tests, speed and accuracy were calculated and in spiral tests, standard deviation of frequency filtered radial drawing velocity was calculated.
However, in Figure 8, there is no asymptotic limit due to an increase in the drawing ratio, λ, and draw stress, σd, with the drawing velocity.
Transmission electron microscopy (TEM) investigations revealed an exceptionally high degree of local MWCNT alignment with an angular deviation of <10° (HDPE) and <20° (iPP and PB-1) parallel to the films' drawing direction for a broad range of drawing velocities.
The effects of several important parameters are investigated in terms of nondimensional groups, including: fiber draw speed, inert gas velocity, furnace dimensions, gas properties, and dopant properties on the flow, temperature and dopant concentration distribution.
The velocity of drawing movements was computed and the amplitude of the involuntary dyskinetic movements was measured as the standard deviation of the drawing velocity (SD-DV).
Readers use velocity values that are computed by RSS to draw the velocity curve.
In drawing these velocity diagrams it is important to note that the flow typically leaves the trailing edges of the blades at approximately the trailing edge angle in the coordinate frame attached to the blade (i.e. relative frame for the rotor, absolute frame for the stator).
