The symbol for surface roughness and machining parameters is included in the mechanical version of AutoCAD AutoCADu Mechanical. See the AMSURFSYM command (ribbon Annotations). To draw the surface symbol in a plain AutoCAD or AutoCAD LT you can use the dynamic block Roughness from the CAD Blocks library. It conforms to the ISO 1302 standard.
Finish Symbols: There are also symbols that are called ''finish symbols''. These symbols show the welder how to actually create the contour. Keep in mind the word ''finish''. The finish symbol reveals how to finish a weld. For example the following letters are used to convey this information on a symbol: C = chipping; M = Machining; G = Grinding

The THORS Engineering Drawings for Machining course introduces the learner to the unique features of a machining engineering print and offers insight into the finishing processes used to ...
Symbols Meaning (a) Basic Surface Texture Symbol. Surface may be produced by any method except when the bar or circle, (b) or (d), is specified. (b) that material must be provided for that purpose. Material Removal By Machining Is Required. The horizontal bar indicates that material removal by machining is required to produce the surface and (c)
Use this command to create surface texture symbols and place them on your drawing sheet or part. There are several types of symbols; Basic, Machining required and Machining prohibited and so on. The symbol can rest on an entity such as a line or be extended with a leader terminator. There are general and attribute options for each type.

roughness average values machining allowance basic surface texture symbol roughness average values (a). specify in microinches, micrometers, or roughness grade numbers. maximum and minimum roughness average values specify in microinches, micrometers, or roughness grade numbers. maximum waviness height rating (b) specify in inches or millimeters
Too little and you reduce the quality of your product. If you want the finish that''s cheap and cheerful to hit with most CNC machines, specify no finer than a 64 µ" finish. A 32 µ" finish won''t add much cost, and a 16 or even an 8 µ" finish can be done, but now you''ll be looking at increasing costs.
Position of Auxiliary Symbols for Surface Symbols An auxiliary symbol indicating a surface roughness value, cutoff value or reference length, machining method, grain direction, surface undulation, etc. is placed around the surface symbol as shown in Fig. 1. Fig. 1 Positions of Auxiliary Symbols a: Ra value b: Machining method
Symbols for Indicating Surface Finish. The quality of a surface finish on a metal surface produced by production method other than machining is shown on the drawing by a tick symbol as shown in figA. This basic symbol consists of two legs of unequal length.
Steel surface finishes are often an important aspect of custom machine parts. Sometimes steel surface finish is also referred to as surface texture or Surface Roughness. The surface finish of a machine part may be important to reduce friction with other machine parts or to improve the aesthetics of the part.

If you have not read "9 Basic Steps to Reading Welding Symbols" it may be worth taking a look before continuing with this post. The "9 Basic Steps to Reading Welding Symbols" focuses on fillet welds, but goes thru the basics of the welding symbol (arrow, reference .
Symbol (with top line) means: machining mandatory (surface roughness ). µm Symbol (with circle in the vee) means: machining prohibited (surface roughness ). milled µm METRIC SURFACE ROUGHNESS VALUES ARE INDICATED BY THE UNIT: MICROMETER ( ). SYMBOLS: There are a number of symbols in use, all of which have a specific meaning.
Special symbols are used on a drawing to specify where welds are to be located, ... finish by chipping, an M means machining, and a G indicates grinding. Figure 3 52 shows how contour and finish symbols are applied to a welding symbol.
A symbol that appears within the welding symbol that tells the welder how to complete the finished welded joint. Finish symbols indicate the need for processes like grinding, power brushing, or machining.
Honing is an abrasive machining process that produces a precision surface on a metal workpiece by scrubbing an abrasive stone against it along a controlled path. Honing is primarily used to improve the geometric form of a surface, but may also improve the surface texture.. Typical applications are the finishing of cylinders for internal combustion engines, air bearing spindles and gears.

Surface finish, also known as surface texture or surface topography, is the nature of a surface as defined by the three characteristics of lay, surface roughness, and waviness. It comprises the small, local deviations of a surface from the perfectly flat ideal (a true plane).. Surface texture is one of the important factors that control friction and transfer layer formation during sliding.
Since surface texture is dependent on manufacturing process, shaft drawings should designate "fine grinding" or "diamond grinding" in addition to the usual surface finish symbol (Figure 2). Avoid vendors who achieve the designated surface finish by filling in the .
