On a manufactured part, in for rework and refurbish, a blend radius measurement is taken after removing a defect –often by grinding– and then refilling the material through an additive process, and then shaping, grinding, and polishing the new materials back down to the original surface height.
The Blend Radius measurement in this application checks how well the repair matches the surrounding original surface in height and shape. 4D InSpec’s three dimensional measurement is a great way to assess this interface between the old and new surfaces.
Feature analysis, a screen built into every 4D InSpec software package, helps to determine if a part is in specification or not, based on finding and quantifying surface features that fit within your custom parameters for height, depth, width, and so on.
