Scale Used In Engineering Drawing

Find an even whole number dimension on the drawing and check it with the scale.

Scale used in engineering drawing.

Then consider the reduction scale ratios in required format 1 2 1 5 etc. The engineer s scale came into existence when machining parts required a greater precision than the usual binary fractionalization. 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. You can use this technique to check if you have the scale set correctly for your printed drawings.

Hence graphical scale is used as the drawing shrinks the scale will also shrink. But the change is while representing the drawing on a sheet. To scale a si drawing. 1 4 or 1 8 imperial units us scales.

The number 1 means 1 graduation of 1 inch represents 1 foot. 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. Engineers typically use this scale for drafting and blueprint creation.

Multiply the measurement on the drawing with the denominator. When the drawing ages the engineer s scale shrinks and may not give accurate results. Where the denominator is the number after the colon. An engineering drawing is a type of technical drawing that is used to convey information about an object.

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. We use the enlarged scales for very small objects. 1 20 and 1 40 scales are used for working plans.

More than one scale may be used on a drawing. Typically in civil engineering applications 1 10 1 10 is used exclusively for detail drawings. In this case all the scales used on the drawing should be indicated. Graphical scales are used in survey maps.

No changes in dimensions. Check the drawing scale in the example at the left the scale is 1 1 0 use a engineering scale. 1 20 1 50 or 1 100 si units or. This is the same drawing of the v block but at a scale of 1 2.

Changes will be only at the point of drawing. Blueprint drawings are typically drawn in.
