Mar 31, 2018· Surface Finish can be said as the surface texture or surface topography. In Mechanical Engineering Surface finish and the surface roughness, both are referred to same. Surface Roughness is finely spaced surface irregularities. Lay is simply the pattern directions which are produced from the different operations.
Surface roughness, also called surface texture or finish, is a trait of any surface. The design engineer usually specifies the required surface roughness of a flange sealing surface to ensure proper function of the flange in the joint. Surface roughness is usually specified with a "check mark" symbol on a drawing as shown in the figure below.
May 16, 2012· Jeff, I''m not at work now and don''t have SW here so I can''t check other options, but I know that if you choose the bevel weld symbol then you have options to add finish annotations, and grind is one of them.
Surface Roughness symbol in drawing Surface roughness symbol is given to convey manufacturing process related information only. Unless written specifically on the symbol, they do not carry the surface texture type ( plated / milled / cold drawn). These symbols are given irrespective of material and its surface condition.
Introduction Dimensions – the sizes and geometric features of a component specified on the part drawing. How well the parts of a product fits together. Tolerance – Allowable variation in dimension. Surface – affects product performance, esthetic and ''wear''
Click the Annotate tab Symbols panel Surface Texture. Select an object to attach the surface texture symbol to. If you attached the symbol to a line, in the drawing area, specify the start point for the leader. If you attached the object to an arc, circle, ellipse or spline, skip to the next step. Specify one or more points to define the vertices of the leader, and then press ENTER.
Graphical Symbols For Surface Texture The above slide shows the conventional method of indicating a surface finish requirement on a technical drawing, implying to someone measuring the surface that a maximum Ra value of µm is allowed. The symbol would also indicate the maximum allowable surface finish to the person producing the surface.

All surfaces requiring finishes produced by grinding, lapping or superfinishing techniques should be noted, and the final surface designated using ANSI/ASME, Surface Texture and ANSI/ASME, Surface Texture Symbols. The digits shown in the surface texture symbol indicate average surface texture.
Surface grinding is the most common of the grinding operations. It is a finishing process that uses a rotating abrasive wheel to smooth the flat surface of metallic or nonmetallic materials to give them a more refined look by removing the oxide layer and impurities on work piece surfaces.

As for machining to iron and steel castings, the surface finish smooth degree is also an important requirement. The following is the conversion chart is from dandong foundry, for Ra (um), Ra (micro inch), Rz (um), RMS and finish degree in China and USA, including the related finish methods.
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 manufacture the specified machined component.
Surface Finish Symbols, Callouts, and Standards. In the United States, surface finish is usually specified using the ASME standard. The rest of the world commonly uses International Organization for Standardization (ISO) 1302. Callouts and symbols used for different surface finishes can be slightly different, so we''ll look at a couple.

Jul 17, 2008· When we introduced Custom Symbols, which must have been 4 or 5 releases ago, we included a set of basic Finish Symbols under the category ''Unigraphics Symbols''. Also as part of our PMI imitative we include the ability to add Finish Symbols to your model which can later be inherited onto your drawings if desired. John R. Baker,

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
