Direct part marking (DPM) is a process to permanently mark parts with product information including serial numbers, part numbers, date codes, and barcodes. This is done to allow the tracking of parts through the full life cycle .
Means that a feature of size is at the limit of its size tolerance in the direction that leaves the most material on the part. Thus an internal feature of size (e.g., a hole) at its smallest diameter, or an external feature of size (e.g., a flange) at its biggest thickness. The GD&T symbol for MMC is a circled M.
In such cases, the main message is padded with 0 bits in the beginning. These bits are not included in the check word calculation and should be skipped during decoding. The total matrix capacity for a full symbol can be calculated as (112+16*L)*L for a full Aztec code and (88+16*L)*L for a compact Aztec code, where L is the symbol size in ...
Data Matrix Symbol: There are a number of protocols that can be used for measuring the print quality of a data matrix symbol, at the supplier's discretion. This includes ISO/IEC 15415, AIM DPM-1-2006, or SAE AS9132. If a data matrix symbol is ever found to be erroneous, unreadable, or otherwise unacceptable, two diagonal lines should be used to ...
Total face width is the actual dimension of a gear blank including the portion that exceeds the effective face width, or as in double helical gears where the total face width includes any distance or gap separating right hand and left hand helices. For a cylindrical gear, effective face width is the portion that contacts the mating teeth.
A Data Matrix on a Mini PCI card, encoding the serial number 15C06E115AZC72983004. The most popular application for Data Matrix is marking small items, due to the code's ability to encode fifty characters in a symbol that is readable at 2 or 3 mm 2 (0.003 or 0.005 sq in) and the fact that the code can be read with only a 20% contrast ratio.

The symbol has a code point in Unicode at U+2300 ⌀ DIAMETER SIGN, in the Miscellaneous Technical set. It should not be confused with several other characters (such as U+00D8 Ø LATIN CAPITAL LETTER O WITH STROKE or U+2205 ∅ EMPTY SET) that resemble it but have unrelated meanings. [5] It has the compose sequence Composedi. [6]
