Nominal Actual Comparison

Nominal Actual Comparison can be used to assess the accuracy, deviation, and tolerance of an object, and identify any errors or defects in its manufacturing process.

Nominal Actual Comparison

Nominal Actual Comparison is a method of comparing the nominal dimensions of an object, such as its design specifications or CAD model, with its actual dimensions, obtained from CT scanning or other measurement techniques. Nominal actual comparison can be used to assess the accuracy, deviation, and tolerance of an object, and identify any errors or defects in its manufacturing process.

Visualising a Nominal Actual Comparison

Most commonly a 3D compare is displayed as a colour map where the colours represent the magnitude of deviation between the reference and measured objects. A colour scale between red and blue is usually used where green lies in the middle identifying areas where there is minimal deviation.

The comparison can also be visualised in 2D where a coloured whisker plot is used.
