Minutes of Proceedings of the Institution of Civil Engineers The true position of a slot is crucial for ensuring the proper functioning of mechanical assemblies It guarantees that the slot is aligned

In this example, the true position of the hole pattern has three datum features ; central hole B and

true grit redemption slot The feature axis would then have to lie inside of these cylinders BTW, it is perfectly OK to have a hole with a true position tol of at MMC to the

A position tolerance is the total permissible variation in the location of a feature about its exact true position Positional tolerances for cylindrical

true wallet slot The true position is calculated as twice the 3D distance between the measured and the nominal point This True Position value represents a

Once the feature control frame is assigned, an imaginary tolerance zone is defined and located about true position The datum features are identified by datum
