Performing a Datum Alignment using Control X Before the scan of a manufactured part can be inspected using Control X, it must first be  aligned to its nominal CAD model.  The nominal CAD model represents the ‘perfect’ shape.  Once aligned, all of the Control X inspection functions, including Color maps, Whisker plots, 2D and 3D dimensions, Geometry Deviation, 2D Twist Analysis and more can all take place. Consider the water pump cover shown below, prior [...]

Let’s say that this water pump cover needs to lie flat against its mating surface to within a specific GD&T Flatness Callout. We’ve seen, in the past, that Control X can check for GD&T Callout information and return pass/fail conditions.  But we can also use Control X to determine the amount that a part is in or out of a ‘Flatness’ spec by turning on a localized color map that we call a ‘Fitting Deviation’.
