A machine tool is a machine for handling or machining metal or other rigid materials, usually by cutting, boring, grinding, shearing, or other forms of deformations. Machine tools employ some sort of tool that does the cutting or shaping. All machine tools have some means of constraining the workpiece and provide a guided movement of the parts of the machine. Thus, the relative movement between the workpiece and the cutting tool is controlled or constrained by the machine to at least some extent, rather than being entirely "offhand" or "freehand". It is a power-driven metal cutting machine which assists in managing the needed relative motion between cutting tool and the job that changes the size and shape of the job material.
The Bullard Machine Tool Company was a large American machine tool builder. It specialized in vertical boring mills and was largely responsible for the development of the modern form of that class of machine tools.
John Edson Sweet was an American mechanical engineer, inventor, professor, businessman and president of the American Society of Mechanical Engineers from 1884–1885. He is known for building the first micrometer caliper in 1873, for making tools, and for inventing the "straight line" engine.
Brown & Sharpe is a division of Hexagon AB, a Swedish multinational corporation focused mainly on metrological tools and technology. During the 19th and 20th centuries, Brown & Sharpe was one of the best-known and most influential machine tool builders and was a leading manufacturer of instruments for machinists. Its reputation and influence were such that its name is often considered to be inseparably paired with certain industrial standards that it helped establish, including:
A turret lathe is a form of metalworking lathe that is used for repetitive production of duplicate parts, which by the nature of their cutting process are usually interchangeable. It evolved from earlier lathes with the addition of the turret, which is an indexable toolholder that allows multiple cutting operations to be performed, each with a different cutting tool, in easy, rapid succession, with no need for the operator to perform set-up tasks in between or to control the toolpath. The latter is due to the toolpath's being controlled by the machine, either in jig-like fashion, via the mechanical limits placed on it by the turret's slide and stops, or via digitally-directed servomechanisms for computer numerical control lathes.
James Hartness was an American inventor, mechanical engineer, entrepreneur, amateur astronomer, and politician who served as the 58th governor of Vermont from 1921 to 1923.
The Warner & Swasey Company was an American manufacturer of machine tools, instruments, and special machinery. It operated as an independent business firm, based in Cleveland, from its founding in 1880 until its acquisition in 1980. It was founded as a partnership in 1880 by Worcester Reed Warner (1846–1929) and Ambrose Swasey (1846–1937). The company was best known for two general types of products: astronomical telescopes and turret lathes. It also did a large amount of instrument work, such as equipment for astronomical observatories and military instruments The themes that united these various lines of business were the crafts of toolmaking and instrument-making, which have often overlapped technologically. In the decades after World War II, it also entered the heavy equipment industry with its acquisition of the Gradall brand.
Jeffboat was a shipyard in Jeffersonville, Indiana founded by James Howard in 1834, a builder of steamboats. The company was owned by the Howard family until it was sold leading up to World War II. Following the war, it became known as the Jeffersonville Boat and Machine Company and later changed its name to Jeffboat, the more commonly used short form of its name. The company was the largest inland shipbuilder in the United States and the second-largest builder of barges before it closed in 2018.
Oakley is a neighborhood in Cincinnati, Ohio, United States, that borders Pleasant Ridge, Madisonville, and Hyde Park. Oakley's business district, called Oakley Square, lies along Madison Road. Oakley is a primary thoroughfare and a major crosstown artery in Cincinnati.
Makino Milling Machine Co., Ltd., commonly known as Makino, is a machine tool builder with global sales and service, headquartered in Japan.
Pratt & Whitney Measurement Systems is an American multinational corporation that specializes in producing high-precision measuring instruments and systems.
Foundry Products Operations was a subsidiary operation of the Cincinnati Milling Machine Company (CMM), a company which no longer exists. Some parts of the company evolved into the present Milacron, Inc. and Cincinnati Machine. CMM relied heavily on castings for the manufacturing of its machine tool products. The castings were produced at Cincinnati foundries owned by CMM and at foundries independent of CMM, between 1907 and 1988.
Walter L. Rapp (1879–1974) was an architect in Cincinnati, Ohio. He was the "last member of an important Cincinnati architectural dynasty" and one of several prominent Ohio architects to graduate from Massachusetts Institute of Technology. He was part of Rapp & Son after 1901; Rapp, Zettel & Rapp from 1903–1912; Zettel & Rapp from 1913–1930 and Rapp & Meacham from 1931-1958 with Standish Meacham, Rapp's son-in-law. Rapp & Meacham were best known for their residential work, projects written about in a biography on W.L. Rapp authored by his daughter, "Mrs. Standish (Eleanor) Meacham".
Geier is a common surname in Germany and somewhat less common among German-American people. It is also found as a French surname, and as Russian surname. The latter probably is associated with German emigration to Russia in the 17th and 18th centuries. The surname Geier is often considered to be interchangeable with Geyer, although some sources ascribe a different origin and meaning to the two surnames. German migrants to English-speaking countries often Anglicize Geier as Geyer, though this change has become less common in recent years. Similarly, Geier has often been mistakenly changed to Geyer, and vice versa in legal papers such as birth certificates and migration documents, especially in areas where the name is uncommon, or one version is vastly prevalent.
A machine tool builder is a corporation or person that builds machine tools, usually for sale to manufacturers, who use them to manufacture products. A machine tool builder runs a machine factory, which is part of the machine industry.
The following is a timeline of the history of the city of Cincinnati, Ohio, USA.
Milling is the process of machining using rotary cutters to remove material by advancing a cutter into a workpiece. This may be done by varying directions on one or several axes, cutter head speed, and pressure. Milling covers a wide variety of different operations and machines, on scales from small individual parts to large, heavy-duty gang milling operations. It is one of the most commonly used processes for machining custom parts to precise tolerances.
Milacron is an American limited liability company that manufactures and distributes plastic processing equipment for fields such as injection molding and extrusion molding. Milacron is one of many operating companies that make up Hillenbrand, Inc. Hillenbrand acquired Milacron in November 2019.
The American Machinist is an American trade magazine of the international machinery industries and most especially their machining aspects. Published since 1877, it was a McGraw-Hill title for over a century before becoming a Penton title in 1988. In 2013 it transitioned from combined print/online publication to online-only.
Alfred W. Pettibone was one of the first Bellingham residents and pioneers who actively participated in the city's formation, in particular developing the merchandise trade and real estate businesses.
