Direct part marked symbols
The Axicon 12800 and Axicon 12900 are designed to read direct part marked (DPM)
2D symbols that are often etched or dot peened onto metallic surfaces. These
symbols can be verified in accordance with ISO/IEC 15415 or ISO/IEC TR 29158
(formerly known as the AIM Quality Guideline for Direct Park Marking). This second
approach allows for the angle of illumination to be changed, so the user can select
angles of 45º, 30º, or 90º, and also whether the 30º illumination should be on all
four sides or only two sides.
The Axicon 12800 is designed to read symbols on the same plane as its base, while
the Axicon 12900 has an adjustable height. This means that the Axicon 12900 can
be used to read DPM symbols marked on more unusually shaped objects or where
the marking is slightly recessed. The appropriate buttons to change the angle of
illumination appear at the top of the main command window, to the right of the
green x icon.
You should first try to see if you can obtain an acceptable pass grade by using the
ISO/IEC 15415 standard, and then if not, by using the ISO/IEC TR 29158 (AIM-DPM)
approach. The 2D configuration settings will need to be changed to allow for the
AIM-DPM approach and for any other requirements such as those for the USA’s
Department of Defense’s MIL 130 standard.
If you are verifying 2D symbols produced on highly reflective surfaces, you will have
to try out these options to see if you can obtain a suitable pass grade.
The tabs in the main window provide the same type of information as they do for
the Axicon 12600 and 12700.
