OVERVIEW

From basic blueprint reading to advanced dimensional metrology and measurement uncertainty, this series provides comprehensive knowledge for practitioners and decision makers: machinists, inspectors, engineers, managers and corporate executives.

Our customers face increasing demands for highly sophisticated mechanical parts and assemblies, at lower cost. It is important to understand how mechanical designers define tolerances, and the implications to manufacturing and metrology. Indicate Technologies Inc. has partnered with the International Institute of GD&T to present a seminar series that explores the implications of GD&T as it applies to all manufacturing and design disciplines. 

Participants will gain critical insight from both technical and management perspectives that will allow them to intelligently balance design complexity and cost pressures.

The 8 seminars have been organized into 8 Educational Tracks based on Job Function.  See the Job Function Chart for the seminars that apply to your role in your department.
