KEYNOTE PRESENTATION: The GD&T Measurement Conundrum
We all want to measure “right,” but sometimes measuring “wrong” is the best decision to make. Modern measuring equipment and sophisticated software provide significant benefits in versatility and automation, but with great flexibility comes great responsibility in implementation. Equipment like coordinate measuring machines (CMMs) provide seemingly endless options for any specific measuring task. The CMM user needs to understand design intent (GD&T), software options and their machine limitations to determine the optimal measuring approach. In many cases, the “theoretically correct” method does not provide the best overall solution. This presentation will use a variety of measurement examples to highlight the GD&T Measurement Conundrum and present best practice strategies when using modern measuring instruments.
