Core Capabilities

  • 2. Root Sum Squared (RSS) Analysis

    Recognizing that it is statistically improbable for every part to be at its worst-case limit simultaneously, engineers use the RSS method. This assumes a normal distribution (bell curve) of manufacturing variations. Principle: Assumes all dimensions in the assembly are

    • Principle: Assumes all dimensions in the assembly are simultaneously at their worst possible extreme limits (e.g., all parts are at maximum material condition or all at minimum).
    • Formula: $T_assembly = \sum |t_i|$
    • Result: A guaranteed 100% assembly rate, but often leads to overly tight, expensive manufacturing tolerances.
    • Application: Critical safety components (e.g., aerospace, medical devices) where failure is non-negotiable.
