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

  1. How to insure interchangeability of mating parts.
  2. How to make additional quality and productivity improvements.
  3. How to bid contracts with increased confidence.
  4. 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

Your instructors

Joseph Gladkowski is the senior faculty person for the Machine Tool Technology Program at Joliet Junior College and has taught college classes since 1995. He has 26 years of hands-on experience as a tool and die maker, with a concentrated interest in die making and mold making. Joe has an A.A. from Joliet Junior College and a B.A. from Lewis University.

Mathew Higgins is a Joliet Junior College faculty member who retired from Caterpillar after 31 years of experience. He was a machinist for twenty of those years, worked as a manufacturing engineer designing fixtures and tools, as a tool analyst, and as a senior numerical control programmer. He knows the real-world demands made on operators and has years of experience training operators. Matt served on CAT recertification teams and customer certification teams. Prior to joining the JJC faculty, he worked for MTH Tool (Plano), a manufacturer of turbine pumps, designing flow layouts. Matt received an A.A.S. degree in Supervision.
