WebRoundness = (Dmax - Dmin) / 2 Dmax: Maximum value Dmin: Minimum value DISADVANTAGES There is a limit to the accuracy of the measurement, as the value is an average of two-point measurements. Additionally, an error may occur due to the differences in how the micrometer measurement terminal is placed on the target. WebThe meaning of CYLINDRICITY is the quality or state of being cylindrical.

WebCylindricity. is the 3D version of roundness. It assesses how closely an object comes to a perfect cylinder, meaning that it is not only round, but also straight along its axis. The simplest example that demonstrates the need for cylindricity is a pin which is required to pass completely through a bore with a tight diametral tolerance. WebThe equivalent designations for the analysis of cylindricity are LSCY, MZCY, MCCY and MICY. Minimum Zone Reference Circles (MZCI) Defined as two concentric circles positioned to enclose the measured profile such that their radial departure is a minimum. The roundness value is then given as the radial separation. V RONt (MZCI) P P to V WebPut the stylus on the measurement point on the datum circle, and then put the stylus on the measurement point on the target circle to measure the concentricity. The stylus only comes into light contact with the surface and does not scratch the target. Measurement screen a Datum circle b Target circle c Concentricity measurement result poolware cloud login
