Drawing high-performance glass fiber lightguides at high speeds
Optical Fiber Communication, 1985During the past decade, significant advances have been made in the drawing and coating of glass fiber lightguides for use in telecommunications systems. This progress has been the result of contributions from numerous investigators that have added to the legacy of an ancient art as described in a recent review.1 Lightguides for telecommunications ...

Strain rate effect in high-speed wire drawing process
Modelling and Simulation in Materials Science and Engineering, 2002This paper presents a study on the strain rate effect during high-speed wire drawing process by means of finite element simulation. Based on the quasistatic stresses obtained by normal tensile tests and dynamic stresses at high strain rates by split Hopkinson pressure bar tests, the wire drawing process was simulated for low carbon steel and high ...

Efficient Speeding Up Scheme of AutoCAD Drawing
2013The development of machinery automation enables AutoCAD graphics software to practice more universally. Depending on its exclusive advantages, this software has played a very good role in drawing mechanical graphics. Compared to previous traditional manual drawing, CAD drawing owns many advantages, operating speed, dimensional accuracy, graphic scale ...

High speed welding of deep drawing low carbon steel
ICALEO '88: Proceedings of the Laser Materials Processing Conference, 1988Armco designed a program to evaluate the laser weldability of a number of its products, in particular the deep drawing steels used to fabricate automotive body parts. Both coated and uncoated steels have been laser welded. Tensile, fatigue, microstructural, mircrohardness, corrosion, formability, and fracture toughness tests have been run on laser butt-

EFFECT OF DRAW FURNACE GEOMETRY ON HIGH-SPEED OPTICAL FIBER MANUFACTURING
Numerical Heat Transfer, Part A: Applications, 2000Abstract The motivation of manufacturers to pursue higher productivity and low costs in the fabrication of optical fibers requires large diameter silica-based preforms drawn into fiber at very high speed. An optimal design of the draw furnace is particularly desirable to meet the need of high-volume production in the optical fiber ...

Effects of Direction upon Speed of Mirror-Drawing
The American Journal of Psychology, 1963Method: Subjects. Forty-eight right-handed girls served as the Ss. They were randomly selected from a group of 303 right-handed girls in a third semester course in English, required of all Liberal Arts students. Apparatus and materials. Whipple's mirror-drawing apparatus,2 two stop-watches, an accumulative timer, and a stimulus-sheet (Fig. 1) were used

Influence of drawing speed on some properties of acrylic fibers
Journal of Applied Polymer Science, 1981AbstractThe effect of drawing speed on several properties of acrylic fibers has been examined. The acrylic fibers were prepared by the wet‐spinning process. The coagulation bath contained 30–70% DMF and was held at a temperature varying from 10–45°C. From x‐ray diffraction measurement, the orientation of finished fibers increased with an increase in ...
