Scale Used In Engineering Drawing

Then consider the reduction scale ratios in required format 1 2 1 5 etc.

Scale used in engineering drawing.

Multiply the measurement on the drawing with the denominator. Find an even whole number dimension on the drawing and check it with the scale. 1 60 is normally used only to show large areas of a project. Changes will be only at the point of drawing.

1 20 and 1 40 scales are used for working plans. Graphical scales are used in survey maps. An engineering drawing is a type of technical drawing that is used to convey information about an object. 1 20 1 50 or 1 100 si units or.

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. But the change is while representing the drawing on a sheet. 1 4 or 1 8 imperial units us scales.

More than one scale may be used on a drawing. 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. 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.

Blueprint drawings are typically drawn in. Where the denominator is the number after the colon. You can use this technique to check if you have the scale set correctly for your printed drawings. We use the enlarged scales for very small objects.

Engineers typically use this scale for drafting and blueprint creation. No changes in dimensions. To scale a si 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.

In this case all the scales used on the drawing should be indicated. These is used to locate a huge drawing in a particular sheet. The graphical scale is drawn on the drawing. The engineer s scale came into existence when machining parts required a greater precision than the usual binary fractionalization.

Check the drawing scale in the example at the left the scale is 1 1 0 use a engineering scale. This is the same drawing of the v block but at a scale of 1 2.
