Cannibalization Of Machine Parts
Cannibalization of machine parts, in the maintenance of mechanical or electronic systems with interchangeable parts, refers to the practice of removing parts or subsystems necessary for repair from another similar device, rather than from inventory, usually when resources become limited. The source system is usually crippled as a result, perhaps only temporarily, in order to allow the recipient device to function properly again. Cannibalization usually occurs due to unavailability of spare parts, an emergency, long resupply times, physical distance, or insufficient planning/budget. Cannibalization can also be due to reusing surplus inventory. At the end of World War II a large quantity of high quality, but unusable war surplus equipment such as radar devices made a ready source of parts to build radio equipment. Cannibalization can also be an economic/ecological choice for end of life products. Germany, rather than sell/export functional used cars, will disassemble and store pa ...

Interchangeable Parts
Interchangeable parts are parts ( components) that are identical for practical purposes. They are made to specifications that ensure that they are so nearly identical that they will fit into any assembly of the same type. One such part can freely replace another, without any custom fitting, such as filing. This interchangeability allows easy assembly of new devices, and easier repair of existing devices, while minimizing both the time and skill required of the person doing the assembly or repair. The concept of interchangeability was crucial to the introduction of the assembly line at the beginning of the 20th century, and has become an important element of some modern manufacturing but is missing from other important industries. Interchangeability of parts was achieved by combining a number of innovations and improvements in machining operations and the invention of several machine tools, such as the slide rest lathe, screw-cutting lathe, turret lathe, milling machine and metal ...

USS Independence (CV-62)
The fifth USS ''Independence'' (CV/CVA-62) was an aircraft carrier of the United States Navy. She was the fourth and final member of the of conventionally powered supercarriers. She entered service in 1959, with much of her early years spent in the Mediterranean Fleet. ''Independence'' was decommissioned in 1998 after 39 years of active service. Stored in recent years at Puget Sound Naval Shipyard, Bremerton, Washington, the ex-''Independence'' was towed beginning on 10 March 2017 to Brownsville, Texas for scrapping. She arrived on 1 June 2017 and dismantling was completed by early 2019. Design and construction The s were designed in the early 1950s as a smaller version of the cancelled ''United States''-class "supercarriers". Unlike the ''United States'' class, they were to operate in both the nuclear strike and conventional roles, and were therefore intended to carry a mixed fleet of fighters, light attack and heavy attack aircraft, all of which were to be jets.

Wrecking Yard
A wrecking yard (Australian, New Zealand, and Canadian English), scrapyard (Irish, British and New Zealand English) or junkyard (American English) is the location of a business in dismantling where wrecked or decommissioned vehicles are brought, their usable parts are sold for use in operating vehicles, while the unusable metal parts, known as scrap metal parts, are sold to metal-recycling companies. Other terms include wreck yard, wrecker's yard, salvage yard, breaker's yard, dismantler and scrapheap. In the United Kingdom, car salvage yards are known as car breakers, while motorcycle salvage yards are known as bike breakers. In Australia, they are often referred to as 'Wreckers'. Types of wreck yards The most common type of wreck yards are automobile wreck yards, but junkyards for motorcycles, bicycles, trucks, buses, small airplanes and boats or trains exist too. Scrapyard A scrapyard is a recycling center that buys and sells scrap metal. Scrapyards are effectively a scrap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Complete Knock Down
A knock-down kit (also knockdown kit, knocked-down kit, or simply knockdown or KD) is a collection of parts required to assemble a product. The parts are typically manufactured in one country or region, then exported to another country or region for final assembly. A common form of knock-down is a complete knock-down (CKD), which is a kit of entirely unassembled parts of a product. It is also a method of supplying parts to a market, particularly in shipping to foreign nations, and serves as a way of counting or pricing. CKD is a common practice in the automotive, bus, heavy truck, and rail vehicle industries, as well as electronics, furniture and other products. Businesses sell knocked-down kits to their foreign affiliates or licensees for various reasons, including the avoidance of import taxes, to receive tax preferences for providing local manufacturing jobs, or even to be considered as a bidder at all (for example, in public transport projects with "buy national" rules).

Aircraft Boneyard
An aircraft boneyard or aircraft graveyard is a storage area for aircraft that are retired from service. Most aircraft at boneyards are either kept for storage with some maintenance or have their parts removed for reuse or resale and are then scrapped. Boneyard facilities are generally located in deserts, such as those in the Southwestern United States, since the dry conditions reduce corrosion and the hard ground does not need to be paved. In some cases, aircraft that were planned to be scrapped or were stored indefinitely without plans of ever returning to service were brought back into service, as the aviation market or the demands of military aviation changed or failed to develop as anticipated. Military aircraft The 309th Aerospace Maintenance and Regeneration Group in Tucson, Arizona, the largest facility of its kind, is colloquially known as "The Boneyard". Commercial aircraft Due to the impact of the Covid-19 pandemic on aviation, demand for commercial aircraft sto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canadian National 3254
Canadian National 3254 is a class "S-1-b" 2-8-2 " Mikado" type steam locomotive built by the Canadian Locomotive Company for the Canadian National Railway as the fifth member of the Canadian National class S-1-b. History Revenue service Canadian National 3254 was built in December 1917 by the Canadian Locomotive Company for the Canadian Government Railways where it was originally numbered 2854. In 1918, the Canadian Government Railways was merged with the Canadian Northern Railway to create the Canadian National Railway (CN). During a subsequent renumbering process within the locomotive fleet, No. 2854 was renumbered to 3254. The locomotive had considerable pulling power, could climb grades without incident, and was used to pull heavy freight trains. No. 3254 had a mostly uneventful career, the locomotive continued to pull freight trains for CN, until its last major class 3 overhaul was completed in Allendale, Ontario, and it was retired from revenue service in February 195 ...

Canadian National 3377
Canadian National 3377 is a preserved class " S-1-d" 2-8-2 "Mikado" type steam locomotive currently on display at the Steamtown National Historic Site in Scranton, Pennsylvania. History Canadian National 3377 was built in 1919 by the Canadian Locomotive Company for the Canadian Government Railways where it was numbered 2977. It was later renumbered to 3377 and would spend the rest of its career operating on the Canadian National Railway. It was eventually retired from revenue service in 1961. The locomotive was sold to the Edaville Railroad in September 1961, and then was later moved to Bellows Falls, Vermont and became part of the Steamtown, U.S.A. collection. No. 3377 was the target of copper thieves during its trip to Steamtown; it was never repaired and has been cannibalized for parts for Steamtown's operating Canadian National The Canadian National Railway Company (french: Compagnie des chemins de fer nationaux du Canada) is a Canadian Class I freight railway headqu ...

Union Pacific 844
Union Pacific 844, also known as the "Living Legend", is a class " FEF-3" 4-8-4 " Northern" type steam locomotive owned and operated by the Union Pacific Railroad for its heritage fleet. Built in December 1944 by the American Locomotive Company (ALCO) of Schenectady, New York, No. 844 is one of four surviving FEF Series locomotives and the only one in operation. The locomotive operated in revenue service until 1959. It was stored while awaiting scrapping, along with the rest of the UP steam locomotive fleet. In 1960, railroad leaders recognized the benefits of having a steam program and retained No. 844 for special activities, the kernel of what has become the Union Pacific's heritage fleet. Today, it is one of UP's oldest serving locomotives and the only steam locomotive owned by a North American Class I railroad that has never been retired. History Revenue service In 1944, Union Pacific and the American Locomotive Company (ALCO) collaborated on the FEF-3, a class of ...

4-8-4
Under the Whyte notation for the classification of steam locomotives, represents the wheel arrangement of four leading wheels on two axles, eight powered and coupled driving wheels on four axles and four trailing wheels on two axles. The type was first used by the Northern Pacific Railway, and initially named the Northern Pacific, but railfans and railroad employees have shortened the name since its introduction. It is most-commonly known as a Northern. Overview Development The wheel arrangement was a progression from the Mountain type and, like the Berkshire and Hudson types, an example of the "Super Power" concept in steam locomotive design that made use of the larger firebox that could be supported by a four-wheel trailing truck, which allowed greater production of steam. The four-wheel leading truck gave stability at speed and the eight driving wheels gave greater adhesion. The evolution to the type occurred in the United States of America soon after the Lima Lo ...

Union Pacific
The Union Pacific Railroad , legally Union Pacific Railroad Company and often called simply Union Pacific, is a freight-hauling railroad that operates 8,300 locomotives over routes in 23 U.S. states west of Chicago and New Orleans. Union Pacific is the second largest railroad in the United States after BNSF, with which it shares a duopoly on transcontinental freight rail lines in the Western, Midwestern and Southern United States. Founded in 1862, the original Union Pacific Rail Road was part of the first transcontinental railroad project, later known as the Overland Route. Over the next century, UP absorbed the Missouri Pacific Railroad, the Chicago and North Western Transportation Company, the Western Pacific Railroad, the Missouri–Kansas–Texas Railroad and the Chicago, Rock Island and Pacific Railroad. In 1996, the Union Pacific merged with Southern Pacific Transportation Company, itself a giant system that was absorbed by the Denver and Rio Grande Western Railroad. ...

USS Kitty Hawk (CV-63)
USS ''Kitty Hawk'' (CV-63), formerly CVA-63, was a United States Navy supercarrier. She was the second naval ship named after Kitty Hawk, North Carolina, the site of the Wright brothers' first powered airplane flight. ''Kitty Hawk'' was the first of the three s to be commissioned and the last to be decommissioned. ''Kitty Hawk'' was laid down by the New York Shipbuilding Corporation, Camden, New Jersey, on 27 December 1956. The ship was launched on 21 May 1960, sponsored by Mrs. Camilla F. McElroy, wife of Defense Secretary Neil H. McElroy. ''Kitty Hawk'' was launched by flooding her drydock; the conventional slide-down method was ruled out because of her mass and the risk that she might hit the Philadelphia shore on the far side of the Delaware River. The ship was commissioned 29 April 1961, at Philadelphia Naval Shipyard, Captain William F. Bringle in command. With the decommissioning of on 30 September 1998, ''Kitty Hawk'' became the United States warship with the second ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inventory
Inventory (American English) or stock (British English) refers to the goods and materials that a business holds for the ultimate goal of resale, production or utilisation. Inventory management is a discipline primarily about specifying the shape and placement of stocked goods. It is required at different locations within a facility or within many locations of a supply network to precede the regular and planned course of production and stock of materials. The concept of inventory, stock or work in process (or work in progress) has been extended from manufacturing systems to service businesses and projects, by generalizing the definition to be "all work within the process of production—all work that is or has occurred prior to the completion of production". In the context of a manufacturing production system, inventory refers to all work that has occurred—raw materials, partially finished products, finished products prior to sale and departure from the manufacturing system.
