As a result, the price jigs up and down all day like those of pork bellies or wholesale power (see chart).
That eliminates the need for expensive jigs and tools on the assembly floor to hold parts in position while fitters file and trim in order to get everything to match.No-grow areaIt would be wrong to conclude from the gloom that American businesses will not soon muster again what Keynes called the "spontaneous optimism" that economies need in order to grow.
3D-printed tools, jigs, moulds and dies allow production lines to be set up more quickly.
Crowds of Indonesian men stand knee-deep in running water working their jigs.
Other components, such as 3D-printed tools and jigs, will actually enhance mass-production: BMW's assembly-line workers design and print custom tools to make it easier to hold and position parts.
Sewing machine attachments are jigs and fixtures used with sewing machines to decrease downtime (the time a machine is inoperative) and thus increase productivity by getting the fabric to the needle, aligning and repositioning fabric under the needle, or extracting and disposing of the sewed materials sooner.
He invented new techniques of creating rhythm by combining elements of African American vernacular dance, Irish jigs, and clogging.
Alluvial deposits require little or no comminution; they are usually concentrated by gravity techniques such as jigging or tabling, in which a slurry is passed through jigs or over grooved or ridged tables that retain the denser gold particles while allowing the much less dense sand and gravel to pass over.
Special cramping jigs are set up so that, for example, a wardrobe can be glued up in one operation by power-driven rams.
Machine tools (capable of producing dimensionally accurate parts in large quantities) and jigs and fixtures (for holding the work and guiding the tool) were the indispensable innovations that made mass production and interchangeable parts realities in the 19th century.
Relying on differences in the two physical properties of size and specific gravity, equipment such as jigs, heavy-media baths, washing tables, spirals, and cyclones separate the heterogeneous feed into clean, homogeneous coal and waste products.
