Machine Drawing Question papers

About Machine Drawing : Machine drawings are graphic representations of any part or any assembly of parts which we see all around us. Some of the examples are——-electric fan, switch, gear box, grinder, boiler, valves, electric motor, water pump, printer, car, airoplane, ship etc. Machine drawings give complete information about a part or a component or a group of components working as one unit. This information is in the form of material, measurements, manufacturing process, machining or finishing process, precision required etc. The machine drawings are PRIMARILY used in manufacturing activities. All or part of this information is used for designing a part, its manufacturing, its machining and finishing and also in positioning correctly in the final assembly to obtain the desirable or predetermined performance. The information given by the machine drawings is needed for setting tools, inspection and quality control, sales and service. In advance methods, the machine drawings are translated into / interpreted by digital signals and electronic circuits, leading to higher levels of automation.

More About Machine Drawing :

Technical drawing, drafting or drawing, is the act and discipline of composingdrawings that visually communicate how something functions or is constructed.

Technical drawing is essential for communicating ideas in industry and engineering. To make the drawings easier to understand, people use familiar symbols,perspectives, units of measurement, notation systems, visual styles, and page layout. Together, such conventions constitute a visual language and help to ensure that the drawing is unambiguous and relatively easy to understand. Many of the symbols and principles of technical drawing are codified in an international standard called ISO 128.

The need for precise communication in the preparation of a functional document distinguishes technical drawing from the expressive drawing of the visual arts. Artistic drawings are subjectively interpreted; their meanings are multiply determined. Technical drawings are understood to have one intended meaning.

A drafter, draftsperson, or draughtsman is a person who makes a drawing (technical or expressive). A professional drafter who makes technical drawings is sometimes called a drafting technician.

The art and design that goes into making buildings is known as “architecture”. To communicate all aspects of the shape or design, detail drawings are used. In this field, the term plan is often used when referring to the full section view of these drawings as viewed from three feet above finished floor to show the locations of doorways, windows, stairwells, etc. Architectural drawings describe and document an architect’s design.

Engineering can be a very broad term. It stems from the Latin ingenerare, meaning “to create”. Because this could apply to everything that humans create, it is given a narrower definition in the context of technical drawing. Engineering drawings generally deal with mechanical engineered items, such as manufactured parts and equipment.

Engineering drawings are usually created in accordance with standardized conventions for layout, nomenclature, interpretation, appearance (such as typefaces and line styles), size, etc.

Its purpose is to accurately and unambiguously capture all the geometric features of a product or a component. The end goal of an engineering drawing is to convey all the required information that will allow a manufacturer to produce that component.
