Let's Start Talking

It is well known that multidisciplinary teams bring products to market quicker and more efficiently. But what if the individual team members came from different countries or different backgrounds and all spoke a different language? One word comes to mind – chaos!

The same can be said of product development teams communicating design intent. When each team member views design intent differently due to gaps in knowledge and interpretation of GD&T - chaos ensues!

Most managers at all levels have lacked a core understanding of the business implications these subjects have on product development timelines, product reliability/risk and supplier/customer interactions. The incorrect assumption by most managers is that all of their applicable employees have the necessary skill sets to adequately perform their job tasks at an adequate level. The key question to all managers should be "where and how would their employees have acquired these fundamental skill sets?" GD&T and measurement are not subjects taught at most universities and colleges and are not focus subjects in mechanical engineering (ME) programs. At best the ME is barely introduced to GD&T and even less on measurement. If the ME is not getting adequately trained in these areas then where and how are the remaining disciplines being adequately trained (technicians, tool makers, drafters, designers, quality, statisticians, etc)?

When design intent is clearly communicated products come to market faster and more profitably. Only a cross functional training model can bridge the communication gap between management, R&D and commercialization. Once adopted and spoken by the entire organization GD&T will revolutionize how your teams communicate. Solution = Effective GD&T Training at all Levels!

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)

A Poster Paints a Thousand Words... Read about the History of the Chart here.
