Result Interpretation

ISO 14405-1 Plug Gauge Functional Size (Effective Diameter) Calculator computes Effective diameter (functional size) in m using the defined engineering formula and the input values provided. Effective diameter (functional size) is expressed in m. No universal acceptance threshold is defined by this calculator.

Worked Example

Verified calculation

Given:

  • Maximum measured diameter = 0.01
  • Minimum measured diameter = 0.009992
  • Roundness deviation (Rt) = 1.2E-6

Expected Result:

  • Effective diameter (functional size) = 0.0099919105006335

Engineering Interpretation:

Under the given input conditions, the calculated result is: Effective diameter (functional size) = 0.0099919105006335 m.

The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from deterministically validated test cases.

Formula / Method

functional size = maximum measured diameter - (2 * sqrt(pow(maximum measured diameter - minimum measured diameter, 2) + pow(Rt, 2)) / 2)
