UNIDIMENSIONAL TOLERANCE CALCULATION METHODOLOGY
Keywords:
Tolerance Calculation (TA), Stack-up, Geometric Dimensioning & Tolerances (GD&T), cost optimization, assembly reliability.Abstract
This paper presents an effective and accessible methodology for tolerance analysis designed to support engineers in the industrial manufacturing domain. Product functionality and long-term performance are directly determined by the management of component dimensions and their cumulative effect, known as tolerance stack-up. In Industrial Engineering, there is a constant trade-off: tight tolerances increase production costs (e.g., higher scrap and inspection time), while loose tolerances introduce a high risk of assembly failure and reduced product reliability. Therefore, the efficient and accurate assignment of tolerances is essential for process optimization and maintaining product quality.
