Predicting fracture in high-speed wire drawing

Strength of Materials, 1981
1. A mathematical model of wire drawing speed was constructed, with allowance for inertial terms and the angle of taper, from the theory of viscoplastic flow. The stresses and temperature inside the deformation zone were determined. 2. The model makes it possible to find the critical drawing speeds corresponding to brittle and ductile ...

Lubricating and cooling liquids for high-speed drawing

Vestnik Mashinostroeniya, 2022
The features of the effect of the lubricating-cooling liquid (LCL) on the cutting process during high-speed drawing of the external shaped surfaces are considered. Criteria and recommendations for the selection of coolants for highspeed drawing of workpieces from structural steels are given.

High-speed drawing of steel wire

Steel in Translation, 2013
The increase in productivity due to increase in the drawing speed may be largely lost as a result of more frequent shutdown of the equipment associated with the replacement of worn dies and with wire fracture. The influence of the tool parameters on its wear and the wire fracture is analyzed.

Adjustable speed D-C drives for deep-draw presses

Transactions of the American Institute of Electrical Engineers, Part II: Applications and Industry, 1953
The trend in the automobile industry toward larger and more complex stamped parts for fabricating automobile bodies has necessitated radical changes in the design of stamping presses and their associated drives. The drive problems presented by these more complex machines and operations have led to the development of new drive systems.

Speed, subjectivity and visual conventions in ethnographic reportage drawings

Drawing: Research, Theory, Practice, 2021
Reportage drawing is a way of visual journalism and records opinions as well as observation. In ethnographic fieldwork, reportage drawing has been used as a method of visually documenting ethnographic discoveries. The question is: what are the most significant skills that a reportage drawing artist need to effectively document visual materials?

Circle-Drawing Movements at Different Speeds: Role of Inertial Anisotropy

Journal of Neurophysiology, 2002
This study investigated the role of inertial anisotropy at the hand in causing distortions in movement. Subjects drew circles in the horizontal plane at four locations in the workspace at three instructed paces using elbow and shoulder movements.

Feasibility of High Speed Furnace Drawing of Optical Fibers

Journal of Heat Transfer, 2004
The domain of operating conditions, in which the optical fiber-drawing process is successful, is an important consideration. Such a domain is mainly determined by the stresses acting on the fiber and by the stability of the process. This paper considers an electrical resistance furnace for fiber drawing and examines conditions for process feasibility ...

Speed Up Graph Drawing for Social Network Visualization

2011
Though classical forced-directed algorithms have many advantages on graph drawing, such as good-quality results, flexibility, simplicity, etc., the high running time makes them impractical to real applications. To this end, we propose a community-based approach to speed up graph drawing for social networks under the assumption that the position of a ...
