22、 parts marking performed in using “Data Matrix symbology“ used within the aerospace industry. The ISO/IEC 16022 specifies general requirements (data character encodation, error correction rules, decoding algorithm, etc.). In addition to ISO/IEC 16022 specification, part identification with such symb
23、ology is subject to the following requirements to ensure electronic reading of the symbol. The marking processes covered by this standard are as follows: Dot peening Laser Electro-chemical etching Further marking processes will be included if required. This standard does not specify information to b
24、e encoded Unless specified otherwise in the contractual business relationship, the company responsible for the design of the part shall determine the location of the Data Matrix Marking. Symbol position should allow optimum illumination from all sides for readability. 1.2 Convention The following co
25、nventions are used in this standard: The words “shall” and “must” indicate mandatory requirements. The word “should” indicates requirements with some flexibility allowed in compliance methodology. Producers choosing other approaches to satisfy a “should” must be able to show that their approach meet
26、s the intent of the requirement of this standard. The words “typical”, “example”, “for reference” or “e.g.” indicate suggestions given for guidance only.

29、 BSI5 3 Marking requirements 3.1 General requirements Rows and columns: Rows and columns connected with Data Matrix symbology shall conform to ECC200 in the ISO/IEC 16022 Square versus rectangle: Matrix may be square or rectangular within ECC200 requirements. Square is preferred for easier reading.
30、Quiet zone: The quiet zone (margin) around the matrix shall be equal to or greater than one (1) module size. Round surface: If the marking is made on round/curved surface, the symbol coverage shall be equal to or less than 16 % of the diameter (or 5 % of circumference). Symbol size: To facilitate el
31、ectronic reading of symbol, the overall symbol size should be less than one 25,4 mm (1.000 inch), outside dimension, longest side. Irrespective of matrix size used, the requirements included in this standard shall be applied. Angular distortion of the symbol: Angular deviation of 90-degree axes betw
32、een row and column shall not exceed 7 degrees (see Figure 1 below). Figure 1 Angle of distortion EN 9132:2006Licensed Copy: Wang Bin, na, Thu Aug 24 02:39:06 BST 2006, Uncontrolled Copy, (c) BSI6 3.2 Dot peening 3.2.1 Description of process Dot-peen marking technology typically produces round indent
33、ations on a parts surface with a pneumatically or electromechanically driven pin, otherwise known as a stylus. Critical to the readability of dot-peen marked symbols are the indented dots shape, size, and spacing. The dot size and appearance are determined mostly by the stylus cone angle, marking fo
34、rce, and material hardness. The indented dot created should be suitable to trap or reflect light and large enough to be distinguishable from the parts surface roughness. It should also have spacing wide enough to accommodate varying module sizes, placement, and illumination. The issues involved in m
35、arking and reading dot-peen-marked symbols on metals are different than symbols printed on paper. The first fundamental difference is that the contrast between dark and light fields is created by artificial illumination of the symbol. Therefore, the modules shape, size, spacing, and part surface fin
36、ish can all affect symbol readability. The key to a successful dot-peen marking and reading project is to control the variables affecting the consistency of the process. Symbol reading verification systems can provide feedback of the process parameters to some extent. Marking system operating and ma
37、intenance procedures must be established to help ensure consistent symbol quality. Regular maintenance schedules should be established to check for issues such as stylus wear. Additional processes, like machining dedicated surfaces, may be necessary to improve the symbol readability. Cleaning the pa
38、rt surfaces prior to marking with an abrasive pad to remove coatings, rust, and discoloration, or using an air knife to blow away excess machining fluids, debris, or oil can also increase the symbol readability. 3.2.2 Instructions for determination of marking parameters Determine minimum module size
39、 according to the surfacetexture. See Table 1, Figure 2 (inch) or Figure 3 (mm). Calculate dot size with regard to the above minimum modulesize in choosing stylus angle (60, 90 or 120) depending on maximum depth allowed by Engineering Design requirements.See Table 2 for the optimum dot size. Determi
40、ne matrix size depending on the information coded inthe matrix. (Reference tables in Annex A for minimum matrixsize based on available marking area).

45、surface texture (m) Data capacity: For information, tables in Annex A for Dot Peening show the symbol size and the data capacity compared to the nominal module size and the number of rows and columns relative to surface texture. These tables are based on practical testing. Data Matrix symbol quality
46、 requirements: Below are the symbol quality requirements of the Data Matrix and marking equipment but these may vary according to the design requirements and responsibility. Dot depth is subject to Engineering Design requirements. The Dot depth is based upon the requirements for process, environment
47、 survivability and other material considerations. Stylus radius is also an Engineering Design requirement. The maximum tolerance shall not exceed 10 % of the Stylus radius. Surface colour and colour consistency may be specified as an Engineering Design requirement. In order to maximize readability,
48、variation in surface colour should be minimized. Stylus cone angle (Ref in Annex B) is an Engineering Design requirement. The cone angles permitted are 60, 90 and 120. The tolerance on the cone angle shall be 2. For general quality of mark and stylus life, stylus cone angle of 120 is preferred. Styl
49、us point finish shall be polished. Surface texture shall not exceed 32 inch or 0,8 m. Guidance instructions for grinding are given in Annex B. Stylus point concentricity should be 0,04 mm (0.0016“) total indicator reading, or 0,02 mm (0.0008“) radial point displacement. Point concentricity is referenced to stylus centerline. Hand held grinding of stylus points is not permitted. Dot size shall not exceed 105 % of the nominal module size and shall not be less than 60 % of the nominal module
