Scale Used In Engineering Drawing

An engineering scale also known as an engineer s scale is actually a type of ruler that produces ratio drawings.

Scale used in engineering drawing.

An engineering drawing is a type of technical drawing that is used to convey information about an object. 1 20 and 1 40 scales are used for working plans. No changes in dimensions. The graphical scale is drawn on the drawing.

Example blueprint drawing scale 1 50. For example with an engineering scale it is possible to manually create a drawing that is ten times larger or ten times smaller than the original that the engineer is drawing from. To scale a si drawing. In this case all the scales used on the drawing should be indicated.

When the drawing ages the engineer s scale shrinks and may not give accurate results. Engineers typically use this scale for drafting and blueprint creation. The engineer s scale came into existence when machining parts required a greater precision than the usual binary fractionalization. Hence graphical scale is used as the drawing shrinks the scale will also shrink.

We use the enlarged scales for very small objects. Multiply the measurement on the drawing with the denominator. Typically in civil engineering applications 1 10 1 10 is used exclusively for detail drawings. Changes will be only at the point of drawing.

Where the denominator is the number after the colon. Find an even whole number dimension on the drawing and check it with the scale. Check the drawing scale in the example at the left the scale is 1 1 0 use a engineering scale. Blueprint drawings are typically drawn in.

1 20 1 50 or 1 100 si units or. The number 1 means 1 graduation of 1 inch represents 1 foot. More than one scale may be used on a drawing. These is used to locate a huge drawing in a particular sheet.

A common use is to specify the geometry necessary for the construction of a component and is called a detail drawing usually a number of drawings are necessary to completely specify even a simple component. This is the same drawing of the v block but at a scale of 1 2. 1 4 or 1 8 imperial units us scales. Graphical scales are used in survey maps.

1 60 is normally used only to show large areas of a project. But the change is while representing the drawing on a sheet.
