It is derived from the American system of manufacturing techniques (also called "armory practices"), a set of general techniques and guidelines for manufacturing that was developed in the 19th century. The system calls for using interchangeable parts, which is made possible by a strict system of organization, the extensive use of the machine shop, and quality control systems utilizing gauges to ensure precise and uniform dimensions. It was developed by Aaron Lufkin Dennison, a watch repairman who was inspired by the manufacturing techniques of the United States Armory at Springfield, Massachusetts, which manufactured identical parts, allowing rapid assembly of the final products. He proposed using similar techniques for the manufacture of watches. Before the American system of watch manufacturing was developed, watchmaking was primarily a European business. It involved making certain parts under the roof of a factory while obtaining other parts from piece workers who used their own cottages as workshops. ==Beginning of standardized production== Henry Pitkin and his brother James were jewelry makers in Hartford, Connecticut in the mid-1830s before their business failed as a result of the panic of 1837 and they turned their attention to the manufacture of watches. The brothers were able to construct crude machinery for the production of watches, particularly for the manufacture of pallets. Their first complete movement was completed in 1838; a total of between 800 and 900 watches were completed through 1845. Surviving examples of Pitkin watches showed that the parts were, in fact, interchangeable. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「American system of watch manufacturing」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
