Advanced Blueprint Reading: Geometric Dimensioning and Tolerancing
Registration Information
Geometric Dimensioning and Tolerancing – INDT 1160
Friday, April 25, 2008 8:00am-4:00pm $295
Seminar Location: Seminar is held at Joliet Junior College’s Main Campus, Room C-1006, 1215 Houbolt Road, Joliet, Illinois.
Seminar Description: GD&T is an information packed seminar that will provide you with knowledge of tolerancing tools and techniques.
Geometric dimensioning and tolerancing (GD&T) is used to express engineering configuration from the designer to the manufacturer using a mechanical drawing. When properly specified, the system provides a uniform understanding and interpretation among all persons exposed to the drawing. In 1966 the Department of Defense, industry and educational institutions adopted a common American standard dealing with geometric dimensioning and tolerancing, ANSI/ASME Y14.5M. The problem experienced with this standard is a failure to educate adequately the drawing originators, manufacturers, and quality control personnel in its correct use.
You must be familiar with blueprint reading basics and the use of gauges for measurement.
You will learn
- How to insure interchangeability of mating parts.
- How to make additional quality and productivity improvements.
- How to bid contracts with increased confidence.
- How to interpret and apply ANSI Y14.5M-1982 and ASME Y14.5M-1994 standards.
Who will benefit
- Inspectors
- Supervisors
- Quality assurance personnel
- Engineers
- Drafting personnel
- Tool & die makers & machinists
