Scale Used In Engineering Drawing

Check the drawing scale in the example at the left the scale is 1 1 0 use a engineering scale.

Scale used in engineering drawing.

1 20 and 1 40 scales are used for working plans. These is used to locate a huge drawing in a particular sheet. 1 4 or 1 8 imperial units us scales. When the drawing ages the engineer s scale shrinks and may not give accurate results.

The engineer s scale came into existence when machining parts required a greater precision than the usual binary fractionalization. To scale a si drawing. Then consider the reduction scale ratios in required format 1 2 1 5 etc. We use the enlarged scales for very small objects.

Increasing the drawing scale even more to 1 5 it becomes quite obvious how much extra area are displayed but again the cost is details that can be seen. Hence graphical scale is used as the drawing shrinks the scale will also shrink. Changes will be only at the point of drawing. No changes in dimensions.

Where the denominator is the number after the colon. The number 1 means 1 graduation of 1 inch represents 1 foot. But the change is while representing the drawing on a sheet. This is the same drawing of the v block but at a scale of 1 2.

Find an even whole number dimension on the drawing and check it with the scale. Engineers typically use this scale for drafting and blueprint creation. Graphical scales are used in survey maps. More than one scale may be used on a drawing.

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. An engineering scale also known as an engineer s scale is actually a type of ruler that produces ratio drawings. The graphical scale is drawn on the drawing. In this case all the scales used on the drawing should be indicated.

1 20 1 50 or 1 100 si units or. Typically in civil engineering applications 1 10 1 10 is used exclusively for detail drawings. 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. An engineering drawing is a type of technical drawing that is used to convey information about an object.

1 60 is normally used only to show large areas of a project. Blueprint drawings are typically drawn in.
