Scale Used In Engineering Drawing

But the change is while representing the drawing on a sheet.

Scale used in engineering drawing.

We use the enlarged scales for very small objects. Find an even whole number dimension on the drawing and check it with the scale. When the drawing ages the engineer s scale shrinks and may not give accurate results. The number 1 means 1 graduation of 1 inch represents 1 foot.

Engineers typically use this scale for drafting and blueprint creation. This is the same drawing of the v block but at a scale of 1 2. 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. The graphical scale is drawn on the drawing.

You can use this technique to check if you have the scale set correctly for your printed drawings. 1 4 or 1 8 imperial units us scales. No changes in dimensions. Hence graphical scale is used as the drawing shrinks the scale will also shrink.

An engineering scale also known as an engineer s scale is actually a type of ruler that produces ratio drawings. An engineering drawing is a type of technical drawing that is used to convey information about an object. To scale a si drawing. 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. Graphical scales are used in survey maps. These is used to locate a huge drawing in a particular sheet. Then consider the reduction scale ratios in required format 1 2 1 5 etc.

Where the denominator is the number after the colon. 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. Example blueprint drawing scale 1 50. 1 20 and 1 40 scales are used for working plans.

The engineer s scale came into existence when machining parts required a greater precision than the usual binary fractionalization. Changes will be only at the point of drawing. Multiply the measurement on the drawing with the denominator. 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.

More than one scale may be used on a drawing. 1 60 is normally used only to show large areas of a project.
