What is fractional tolerance?

Answer 1

Fractional tolerance refers to the allowable variation in a measurement or dimension relative to its nominal value, expressed as a fraction of that nominal value. It is commonly used in engineering and manufacturing to ensure that parts fit together correctly and function as intended, even with slight variations in size. This concept helps in maintaining quality control by setting acceptable limits on deviations from specified dimensions. Essentially, it quantifies how much a dimension can vary while still being considered acceptable.
