Featured in this issue: New B-17 Revision , DataMan 7500 Handheld Verifier , and Reading vs. Verification - - AIAG B-17 Revision: 2D Direct Parts Marking Guideline The AIAG (Automotive Industry Action Group) has recently revised its B-17 Guideline which provides guidance for the marking, reading and verification of Data Matrix and/or QR Code symbols marked directly on parts using laser, dot peen, inkjet or other DPM technologies. In its newest version, B-17 incorporates the AIM (Association for Automatic Identification and Mobility) DPM (Direct Part Mark) Quality Guideline DPM-1-2006. The AIM DPM guideline is built upon the concepts developed in the ISO 15415 specification but adds key lighting requirements, a defined auto-exposure routine to handle different part surface reflectance and a much more reliable method of determining the "global threshold" of a code to differentiate between light cells and dark cells. As a result of the release of the B-17 Guideline, the automotive industry has implemented a standard to determine true code quality for contract compliance between the supplier and end customer.

AIAG B-17 Revision:
2D Direct Parts Marking Guideline

The AIAG (Automotive Industry Action Group) has recently revised its B-17 Guideline which provides guidance for the marking, reading and verification of Data Matrix and/or QR Code symbols marked
directly on parts using laser, dot peen, inkjet or other DPM technologies.

In its newest version, B-17 incorporates the AIM (Association for Automatic Identification and Mobility) DPM (Direct Part Mark) Quality Guideline DPM-1-2006.



The AIM DPM guideline is built upon the concepts developed in the ISO 15415 specification but adds key lighting requirements, a defined auto-exposure routine to handle different part surface reflectance and a much more reliable method of determining the "global threshold" of a code to differentiate between light cells and dark cells.

As a result of the release of the B-17 Guideline, the automotive industry has implemented a standard to determine true code quality for contract compliance between the supplier and end customer.
DataMan 7500V Offers High-Reliability Portable Verification

The DataMan series offers the only handheld verifier on the market. Portable verifiers enable manufacturers to perform verification on the factory floor, rather than at a remote or fixed verification station.

AIM DPM, ISO 15415, and AIAG B-17 compliance… software, integrated lighting and fixed optics allow code reading compliance.

Fully integrated design… lighting, camera, processor, and communications—all in an industrial housing. 

Certified calibration… verifiers include a certified and traceable calibration target for establishing AIM DPM reflectance values.
 
Reliable and consistent... industry-leading DataMan readers also provide intuitive software for effortless setup.

Reading or Verification? What's the difference?

The purpose of reading is to locate and decode a mark as quickly and reliably as possible in order to output the data. A good reader can handle variations in marking method, surface texture, etc., and can read at very low resolution.

Verification, however, is the process of inspecting and documenting whether a mark conforms to industry and internationally accepted standards. Once inspected, the verifier will output a grade of the code's quality. Verification systems require higher resolution of the code (5-10 pixels per cell) and all environmental variables, including lighting and part positioning, must be controlled so all mark attributes can be measured.
Reading or Verification? What's the difference?

 

Cognex recommends that you verify codes immediately after marking and before parts enter the downstream manufacturing process in order to prevent no reads. Some industries, such as the U.S. Department of Defense and automotive industry, require that marks pass verification inspection to mark quality standards such as AIM DPM as part of vendor contract compliance for part delivery.

As shown in the screenshot above, easy-to-use software provides detailed metric results as well as graphical image feedback when the "AIM DPM compliant verification" feature is enabled for your DataMan verifier.
