Chamfer Mill
A chamfer ( ) is a transitional edge between two faces of an object. Sometimes defined as a form of bevel, it is often created at a 45° angle between two adjoining right-angled faces. Chamfers are frequently used in machining, carpentry, furniture, concrete formwork, mirrors, and to facilitate assembly of many mechanical engineering designs. Terminology In materials and manufacturing, a ''chamfer'' is used to "ease" otherwise sharp edges, both for safety and to prevent damage to the edges; it may also be a primarily decorative feature. In general terms it may be regarded as a type of ''bevel'', and the terms are often used interchangeably. However, in machining, only the term chamfer is used for the specific technique, practice, and result. In carpentry, a lark's tongue is a chamfer which ends short of the end of a piece in a gradual outward curve, leaving the remainder of the edge as a right angle. Chamfers may be formed in either inside or outside adjoining faces of an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Larks Tongue
Larks are passerine birds of the family Alaudidae. Larks have a cosmopolitan distribution with the largest number of species occurring in Africa. Only a single species, the horned lark, occurs in North America, and only Horsfield's bush lark occurs in Australia. Habitats vary widely, but many species live in drier regions. When the word "lark" is used without specification, it often refers to the Eurasian skylark ''(Alauda arvensis)''. Taxonomy and systematics The family Alaudidae was introduced in 1825 by the Irish zoologist Nicholas Aylward Vigors as a subfamily Alaudina of the finch family Fringillidae. Larks are a well-defined family, partly because of the shape of their . They have multiple scutes on the hind side of their tarsi, rather than the single plate found in most songbirds. They also lack a pessulus, the bony central structure in the syrinx of songbirds. They were long placed at or near the beginning of the songbirds or oscines (now often called Passeri), just ...

Cube
A cube or regular hexahedron is a three-dimensional space, three-dimensional solid object in geometry, which is bounded by six congruent square (geometry), square faces, a type of polyhedron. It has twelve congruent edges and eight vertices. It is a type of parallelepiped, with pairs of parallel opposite faces, and more specifically a rhombohedron, with congruent edges, and a rectangular cuboid, with right angles between pairs of intersecting faces and pairs of intersecting edges. It is an example of many classes of polyhedra: Platonic solid, regular polyhedron, parallelohedron, zonohedron, and plesiohedron. The dual polyhedron of a cube is the regular octahedron. The cube can be represented in many ways, one of which is the graph known as the cubical graph. It can be constructed by using the Cartesian product of graphs. The cube is the three-dimensional hypercube, a family of polytopes also including the two-dimensional square and four-dimensional tesseract. A cube with 1, unit s ...

Passeig De Gràcia
Passeig de Gràcia () is one of the major avenues in Barcelona (Catalonia, Spain) and one of its most important shopping and business areas, containing several of the city's most celebrated pieces of architecture. It is located in the central part of Eixample, stretching from Plaça Catalunya to Carrer Gran de Gràcia. Passeig de Gràcia is regarded as the most expensive street in Barcelona and in Spain. History Formerly known as Camí de Jesús ("Jesus Road"), the Passeig de Gràcia was originally little more than a quasi-rural lane surrounded by gardens joining Barcelona and Gràcia, which was then still a separate town. This was still the case at the time of the first urbanisation project in 1821, which was devised by the Trienio Liberal, liberal city council, and led by Ramon Plana. This project had to be cancelled due to the epidemics that were raging in Barcelona at the time. After the demise of the liberal government with the return of Absolutism (European history), Abs ...

Eixample
The Eixample (, ) is a district of Barcelona between the old city (Ciutat Vella) and what were once surrounding small towns (Sants, Gràcia, Sant Andreu, etc.), constructed in the 19th and early 20th centuries. Its population was 262,000 at the last census (2005). Architecture and design The Eixample is characterized by long straight streets, a strict grid pattern crossed by wide avenues, and square blocks with chamfer#architecture, chamfered corners (named ''illes'' in Catalan, ''manzanas'' in Spanish). This was a visionary, pioneering design by Ildefons Cerdà, who considered traffic and transport along with sunlight and ventilation in coming up with his characteristic octagonal blocks, where the streets broaden at every intersection making for greater visibility, better ventilation and (today) some short-term parking areas. It also provided an area for horse-drawn wagons and carriages to easily turn around. The grid pattern remains as a hallmark of Barcelona, but many ...

Curb (road)
A curb (American English) or kerb (British English) is the edge where a raised sidewalk/pavement or road median, road median/central reservation meets a street/other roadway. History Although curbs have been used throughout modern history, and indeed were present in ancient Pompeii, their widespread construction and use only began in the 18th century, as a part of the various movements towards city beautification that were attempted in the period. A series of Paving Acts in the 18th century, especially the 1766 Paving and Lighting Act, authorized the City of London Corporation to create footways along the streets of London, pave them with Purbeck stone (the thoroughfare in the middle was generally cobblestone) and raise them above street level with curbs forming the separation. The corporation was also made responsible for the regular upkeep of the roads, including their cleaning and repair, for which they charged a tax from 1766. Previously, small wooden bollards had been ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

City Block
A city block, residential block, urban block, or simply block is a central element of urban planning and urban design. In a city with a grid system, the block is the smallest group of buildings that is surrounded by streets. City blocks are the space for buildings within the street pattern of a city, and form the basic unit of a city's urban fabric. City blocks may be subdivided into any number of smaller land lots usually in private ownership, though in some cases, it may be other forms of tenure. City blocks are usually built-up to varying degrees and thus form the physical containers, or "streetwalls," of public spaces. Most cities are composed of a greater or lesser variety of sizes and shapes of an urban block. For example, many pre-industrial cores of cities in Europe, Asia, and the Middle East tend to have irregularly shaped street patterns and urban blocks, while cities based on grids have much more regular arrangements. By extension, the word "block" is an important in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
