ToleranciaSzabály

ToleranciaSzabály, often translated as "Tolerance Rule" or "Rule of Tolerance," refers to a fundamental principle in various fields, particularly in the context of measurement, manufacturing, and engineering. It defines the permissible variation in a dimension, property, or characteristic of a manufactured part or system. This variation is crucial because achieving absolute precision is often impractical and prohibitively expensive. Therefore, a tolerance is established to ensure that a component will still function as intended and be interchangeable with other components produced within the same specified range.

The concept of ToleranciaSzabály is applied across a wide spectrum of applications. In mechanical engineering, it dictates the acceptable deviations in lengths, diameters, angles, and other geometric features of parts like screws, gears, and engine components. In electronics, it can refer to the acceptable variance in resistance values, capacitance, or voltage output of components. The setting of appropriate tolerance values is a complex process that considers the function of the part, the manufacturing capabilities, the cost implications, and the potential impact of deviations on the overall performance and safety of the product.

ToleranciaSzabály is typically expressed using numerical limits, such as a nominal value with an upper and lower deviation, or as a range. For example, a shaft might be specified as 10 mm ± 0.1 mm, meaning its diameter can range from 9.9 mm to 10.1 mm. This principle is foundational to mass production and the concept of interchangeable parts, enabling assembly lines and ensuring that products can be repaired or replaced without needing custom-fitting.
