Radial float refers to the allowable movement or tolerance in a radial direction, often specified in engineering blueprints. In this context, a notation like "RADIAL FLOAT - + 0.06" indicates a tolerance of plus or minus 0.06 units in the radius of a hole. This tolerance is crucial for ensuring proper fit and function in mechanical assemblies. Understanding radial float is essential for accurate interpretation of engineering designs. Properly applying this concept can significantly impact the performance of the final product.
