Roundness is the measure of how closely the shape of an object approaches that of a mathematically perfect circle. Roundness applies in two dimensions, such as the cross sectional circles along a cylindrical object such as a shaft or a cylindrical roller for a bearing. In geometric dimensioning and tolerancing, control of a cylinder can also include its fidelity to the longitudinal axis, yielding cylindricity. The analogue of roundness in three dimensions (that is, for spheres) is s… WebRoundness can be measured in various ways but principally a pin is used which follows the internal diameter of a hole or the external diameter of a shaft when the workpiece rotates. The pin senses the variations in shape and a polar diagram can be drawn and studied ( Figure 15.36 ). Sign in to download full-size image Figure 15.36.
