Is the engineering tolerance for gap a summative value?

Engineering tolerance for gaps relates to the acceptable limits within which a part can be manufactured and still function effectively within an assembly. Tolerance is typically defined as the allowable variation in a physical dimension, which can include both the gap and the fit between parts.

When a tolerance is specified, it often summarizes the permissible limits for manufacturing deviations, thus reflecting a summative value. Engineers use these tolerances to ensure that components fit properly and operate as intended without excessive interference or gap that could lead to performance issues.

In this context, the idea of a summative tolerance indicates that it encompasses both the upper and lower limits that dictate the acceptable range for gaps between components. This ensures that despite production variations, the integrity and function of the assembly are maintained.
