You should note that an abbreviation can have different meanings in different categories. Other international engineering standards include ISO, AS (Australia), AFNOR (France), USA (AISI, ASTM, AMS, ANSI, and SAE), AFNOR (France), UNI (Italy), KS (Korea), Germany (DIN and WR), JIS (Japan), SS (Sweden), and BS (UK).

ASME handles some specific ones related to mechanical engineering. In the United States, the majority of these terms follow Norms ANSI or ASA. So make sure you understand them well! Are Engineering Drawing Abbreviations and Symbols Standardized?Īs with other engineering terms, abbreviations and symbols are subject to standardization. One typo can lead to serious consequences like making something too heavy. To further aid comprehension of what is on paper, abbreviations and symbols must be accurate.

When well used, they result in clean and uncluttered images, allowing the viewer to grasp all important aspects of your design. They should provide all the necessary information to produce a CNC milling part without a hassle.īecause there is no room on your image for text, symbols & abbreviations are relatively less overwhelming. The abbreviations and symbols used must be concise. The design of an engineering drawing is critical. Benefits of Using Abbreviations and Symbols in Engineering Drawings We have prepared an extensive list of engineering drawings abbreviations and symbols for you to reference. If you have found it tough to interpret CNC designs, we’ve got your back! While you may understand the basic terms such as KG and CM, it becomes more difficult when you come across terms such as CYL and EQUI SP. This is where the meanings behind these various pieces come in handy!

Phantom Line: Light, Broken line made up of a series of one long and two short dashes.CNC design is an integral part of CAD/CAM technology. Long break Line: Ruled, light line with freehand zigzags. shows a short break or show partial section. Short Break Line: Heavy, irregular line drawn freehand. Indicates location and extent of a surface area. Section Lines: series of solid or solid and broken lines arranged in a specific pattern.Ĭhain Line: Heavy, broken line made up of a series of long and short dashes alternately spaced. Indicates imaginary cut made through object Indicates imaginary cuts made through objectĪlternate Cutting plane line: solid heavy line or a series of long dashes with arrowheads placed at right angles.

Arrowheads are placed at right angles to the cutting plane line. Preferred Cutting Plane Line: Heavy broken line made up of a series of one long and two small dashes alternately spaced. Leader: Fine, straight line with an arrowhead or round solid dot at one end that is usually drawn at an angle which is used to point directly to a surface for dimensioning or adding a note. Hidden Lines: Broken line of medium thickness that shows edges of an object or outlines not visible to the eyeĬenter Line: Broken line made up of short and long dashes alternately spaced that show the center of circles, arcs, and symmetrical objects.Įxtension Line: Extension lines are fine lines that extend from the object with slight break between the show dimensioning points.ĭimension Line: fine lines with arrowheads, unbroken except where the dimension is placed that show distance given by the dimensions. Object Lines: Represents a thick solid line that shows the visible shape of an object or part.
