Most manufactured products typically consist of multiple components assembled in specified configurations. Such components have specifications for important dimensional characteristics to ensure adequate performance once assembled. The specifications are typically given as tolerances within which components must be produced. Consequently, parts produced outside the specifications are rejected and not used in the assembled product. As dimensional variation is to be expected in produced components, it may accumulate, or stack up, to cause unwanted variation in the assembled product. When this happens, additional costs in scrap and rework would result and may extend to warranty charges and customer dissatisfaction should unacceptable products find their way to the customer. In this paper, issues resulting from tolerance stack-up in capstone production will be addressed. The questions this paper will attempt to answer are: (1) Are students aware of the impact of tolerance stack-up in product development, and (2) What can be done to minimize the potential effects of tolerance stack-up before product launch.
