IIGDT Newsletter November 2018
Leadership starts at the Executive level

Understanding business implications starts at the executive level and driving leadership practices must be embraced and led by example.

Understanding the proper interpretation or intent of GD&T is not equally shared in all disciplines of the process chain. This starts at management and moves down through design, engineering, manufacturing to inspection. We all assume we know GD&T, but the doors of knowledge are closed through non-participation and assumptions.

8-TracksToday our education system fails to address this important aspect of the full system. Many engineers come out of school knowing how to use the latest software and tools, but not the fundamental knowledge GD&T addresses.

Education in manufacturing no longer addresses GD&T period: Inspectors often take a quick one-day course and they are expected to be masters of the GD&T universe: Very disheartening.

When the entire process incorporates a full understanding of GD&T your engineering design group specs products that can be manufactured, assembled and inspected as intended. There will be no ambiguity only true clarity.

8-TracksThe benefit is increased quality, reduced manufacturing costs and most important, providing the customer a product to be proud of.

IIGDT has developed a training track to address weak points in the process chain. We call it Eight tracks to GD&T expertise. IIGDT has developed a relationship chart showing by job responsibility the recommended level of training provided (click on the chart at the right to see full size).

Eight Tracks to GD&T Expertise by Department & Job Function

Each track is designed to aid all management levels in determining which GD&T and measurement courses are essential for each technical and non-technical discipline including managers and executives.

These tracks form an educational path based on the business function you are involved in. Not all of the tracks apply to all of the job functions and no job function has all eight tracks. Each track is made up of one or more courses that are intended to define the minimum level of expertise a particular job function needs to optimally perform their job.

Precision Ground Flatstones

Precision Ground Flatstones

Use these flatstones to improve precision ground surfaces or repair surfaces by removing swelling, dents and nicks.

These stones have been ground flat on both faces with a diamond wheel. The long sides are ground perpendicular to allow stoning up to a shoulder. The ends are unground. The stones are used to remove the swellings which surround the inevitable tiny nicks and dents found on any machined surface. They are much like gage block stones, but with a more aggressive cutting action.

The stone’s porous structure allows asperities to penetrate far enough to be trimmed off. When the raised area is reduced in height to about ten microinches, the force is spread out between two relatively large flat surfaces, and cutting activity substantially stops.
