Dr. HetlandWho Benefits from GD&T?

Design Engineers must not only be knowledgeable of the fundamental principles of geometric dimensioning and tolerancing, but must also be proficient in advanced applications and analysis.

Manufacturing Engineers also need the fundamental knowledge to clearly understand what the designer is trying to say by the engineering drawing. To be efficient, they also must have a high level of competency in applications and analysis to establish process controls that will ensure conformance to engineering requirements, but do it at the least amount of cost.

Metrology Engineers, like the manufacturing engineers, need the same broad base of knowledge, except in this case, the metrology engineers need to have a clear understanding of how to approach the dimensional metrology aspects from both a "proof of compliance" as well as "manufacturing process feedback" perspective.

Focuses on you...

Public Seminars provide a well balanced overview designed to lay the foundation of implementing GD&T. IIGDT Consulting Services builds on that foundation by designing custom courses based on your production. While attending these courses, your employees will received detailed instruction and demonstrations using your drawings, CAD Models and production.

Dr. HetlandProject Specific...

These challenges can bog down the manufacturing process and lead to erroneous solutions. Dr. Hetland has worked in virtually every manufacturing environment throughout the world. This experience brings to your manufacturing department knowledge on spotting areas for improvement in interpreting and applying GD&T.

Dr. HetlandAdvanced Consulting Services...

Proper implementation of GD&T starts at the design phase. The GD&T specifications found on many drawings are often ambiguous and confusing.

GD&T Chart per ASME Y14.5M-2009

IIGDT has released a new GD&T Symbol Chart supporting the ASME Y14.5-2009 standard. Since the original chart was issued based on the 1994 standard several changes have been implemented. In addition, the IIGDT chart provides clear and descriptive explanations for all symbols.

New for this year is the expanded use of 3D profile shown being applied to CAD models to demonstrate the effective use and interpretation of Profile call-outs.

Developed by Dr. Greg Hetland, this guide has been widely used in industry and can be found in many companies across the world.

Size: 24" (610 mm) x 36" (914 mm)
