Circularity vs roundness
WebJun 2, 2008 · Roundness compares measured data with a computer-generated reference circle. Roundness systems have four methods for comparing the measured data to a reference circle for evaluation. It is important to note the reference circle used should be related to the function of the finished component. WebCirc.(circularity): 4π*area/perimeter^2. A value of 1.0 indicates a perfect circle. As the value approaches 0.0, it indicates an increasingly elongated shape. Values may not be valid for very small particles. AR(aspect ratio): major_axis/minor_axis. Enable "Fit Ellipse" in Analyze>Set Measurementsto have the major and minor axis displayed.
