 Machine readable
identification holds the key to manufacturing efficiency
Machine readable
identification is fast becoming a trend throughout many
industry sectors and is used to automatically
identify a variety of products. Manufacturers are marking
parts with machine-readable, permanent two-dimensional (2D)
data matrix codes that are placed directly on the part itself.
Then the part can be tracked throughout its entire life cycle,
including manufacturing and supply chain operations. This
is called Direct Part Mark Identification (DPMI), or Auto-ID.
Established industry DPMI specifications and 2D marking guidelines
are listed in the table below.
DPMI
enables many tangible benefits for manufacturers. This
practice:
• Improves manufacturing process performance
• Identifies quality defects through in-service tracking
• Eliminates manual part data entry errors
• Supports data logging and automated data collection
• Increase yields, and
• As a result, reduces the direct and indirect costs of manufacturing.
Many
manufacturers rely on Auto-ID as well to track high-value
parts to prevent theft or counterfeiting, identify parts
for maintenance and returns, and to resolve warranty
issues and liability claims.

The
two-dimensional 2D Data Matrix code consists of an arrangement
of small dots or squares, marked as either
a square or rectangle. Invented by RVSI Acuity CiMatrix,
the Data Matrix Code is a digital
2D, machine readable symbology that is capable
of storing large amounts of information within a small
physical space. This code has been adopted by many industries,
including aerospace, automotive, and electronic, as the
best symbology for reliable, direct part marking. Compared
to linear barcodes, Data Matrix encodes much more data – 25
to 100 times more information – into a smaller area,
allowing code placement on a wide range of product configurations.
Data Matrix requires less contrast (as low as 20%) between
the code and the marking surface than linear barcodes.
This allows the code to be marked on difficult surfaces
of metal, non-metallic, and plastic components. Built-in
error correction allows the encoded information to be captured
even if the Data Matrix symbol is somewhat degraded.
DAPRA
Marking Systems offers a wide variety of marking
systems to encode 2D symbols directly on parts.
These include dot
peen and laser marking systems. In addition, DAPRA
Marking Systems supplies both fixed-station and
hand-held data
matrix readers and verifiers from Cognex and Microscan.
