Q:Information: - A lathe is a tool that rotates the workpiece on its axis to perform various operations such as cutting, sanding, knurling, drilling, or deformation, facing, turning, with tools that are applied to the workpiece to create an object with symmetry about an axis of rotation. - Cutting is the separation of a physical object, into two or more portions, through the application of an acutely directed force. - Turning is a machining process in which a cutting tool, typically a non-rotary tool bit, describes a helix toolpath by moving more or less linearly while the workpiece rotates. The tool's axes of movement may be literally a straight line, or they may be along some set of curves or angles, but they are essentially linear (in the non mathematical sense). Usually the term "turning" is reserved for the generation of "external" surfaces by this cutting action, whereas this same essential cutting action when applied to "internal" surfaces (that is, holes, of one kind or another) is called "boring". Thus the phrase "turning and boring" categorizes the larger family of (essentially similar) processes. The cutting of faces on the workpiece (that is, surfaces perpendicular to its rotating axis), whether with a turning or boring tool, is called "facing", and may be lumped into either category as a subset. - Knurling is a manufacturing process, typically conducted on a lathe, whereby a pattern of straight, angled or crossed lines is cut or rolled into the material. - St. Martin's Lane is a street in Covent Garden in Central London, which runs from the church of St. Martin-in-the-Fields, after which it is named, near Trafalgar Square northwards to Long Acre. At its northern end, it becomes Monmouth Street. St. Martin's Lane and Monmouth Street together form the B404. - Drury Lane is a street on the eastern boundary of the Covent Garden area of London, running between Aldwych and High Holborn. The northern part is in the borough of Camden and the southern part in the City of Westminster. - Long Acre is a street in the City of Westminster in central London. It runs from St. Martin's Lane, at its western end, to Drury Lane in the east. The street was completed in the early 17th century and was once known for its coach-makers, and later for its car dealers. - Central London is the innermost part of London, England. There is no official definition of its area but its characteristics are understood to include a high density built environment, high land values, an elevated daytime population and a concentration of regionally, nationally and internationally significant organisations and facilities. Over time a number of definitions have been used to define the scope of central London for statistics, urban planning and local government. - The City of Westminster is an Inner London borough which also holds city status. It occupies much of the central area of Greater London including most of the West End. It is to the west of and adjoining the ancient City of London, directly to the east of the Royal Borough of Kensington and Chelsea, and its southern boundary is the River Thames. It was created with the 1965 establishment of Greater London. Upon creation, Westminster was awarded city status, which had been previously held by the smaller Metropolitan Borough of Westminster. - Drilling is a cutting process that uses a drill bit to cut a hole of circular cross-section in solid materials. The drill bit is usually a rotary cutting tool, often multipoint. The bit is pressed against the workpiece and rotated at rates from hundreds to thousands of revolutions per minute. This forces the cutting edge against the workpiece, cutting off chips (swarf) from the hole as it is drilled. - A tool is any physical item that can be used to achieve a goal, especially if the item is not consumed in the process. Tool use by humans dates back millions of years, and other animals are also known to employ simple tools. - The Holtzapffel dynasty of tool and lathe makers was founded in Long Acre , London by a Strasbourg - born turner , Jean - Jacques Holtzapffel , in 1794 . The firm specialized in lathes for ornamental turning but also made a name for its high - quality edge and boring tools .
