Geometric Dimensioning and Tolerancing with Y14.5M-1994

Geometric Dimensioning and Tolerancing
with Y14.5-2009

Geometric Dimensioning and Tolerancing (GDT) was developed as an international language to communicate exactly how a part should be made to achieve the required functionality. When properly applied, GDT is a powerful tool for achieving quality and for reducing costs in design, manufacturing, and inspection.

The American Society of Mechanical Engineers (ASME) document Y14.5-2009 Dimensioning and Tolerancing is the current US standard on this language. Our On-Site Seminar Geometric Dimensioning and Tolerancing with Y14.5-2009, provides in-depth information on the use and interpretation of this important standard.

The Seminar is designed for presentation to a mixed audience of Engineering, Manufacturing, Purchasing, and Quality Department personnel. The program can be customized to meet the specific needs of:

• Engineering, Manufacturing, Purchasing,
or Quality Managers
• Design, Manufacturing, or Production
Engineers
• Part Programmers
• Fixture Designers
• Production Supervisors, Setup Personnel,
or Machine Operators
• Quality Engineers, Gage Designers, or
Inspectors

Geometric Dimensioning and Tolerancing with Y14.5-2009 consists of 14 instructional units and requires approximately 32 to 40 hours for presentation. Participants receive a Seminar Binder containing copies of all presentation materials, copies of selected illustrations, reprints of key articles and technical papers, and additional materials. Various presentation schedules are available to meet your specific requirements.

Please contact us to learn how you can put the power of Geometric Dimensioning and Tolerancing to work for your company.
