The analysis of a part technologiticy in terms of its shape and technical conditions implies the determination of the shape and dimensions of the plane semifinished material
of which the part is to be executed.
The laser beam passes through the transparent part virtually unimpeded and is converted into heat as it is absorbed by the absorbent semifinished material
. The adherend that is transparent to the laser beam also heats up through thermal conduction, and the adherends weld together.
postponing the final configuration of a product later in the supply cycle when better demand information is available) and built-to-order operations allow for diversions of parts and semifinished material
from surplus areas and products to satisfy shortages.
* Exemption from customs duties on capital equipment, spare parts, raw or semifinished materials
The biggest slice of the GNT pie--76 percent--consists of industrial wastes from pulp and paper, iron and steel, stone, clay, glass, concrete, food processing, textiles, plastics, and chemical manufacturing; water treatment; and other industries-in other words, from fabricating, synthesizing, modeling, molding, extruding, welding, forging, distilling, purifying, refining, and otherwise concocting the finished and semifinished materials
of our manufactured world.
Ian Radforth recounts the organizational problems encountered by Robert Hay, a mid-nineteenth century Toronto furniture manufacturer, in managing the mill, forty-five miles away, that supplied raw and semifinished materials
. Richard Rajala traces changing management practices in the Pacific coastal logging industry between 1890 and 1930.
