Interference fits, also known as press fits or friction fits, are fastenings between two parts in which the inner component is larger than the outer component. Achieving an interference fit requires applying force during assembly. After the parts are joined, the mating surfaces will feel pressure due to friction, and deformation of the completed assembly will be observed. Force fits are designed to maintain a controlled pressure between mating parts, and are used w… WebMar 23, 2024 · Tolerances Question 12. Download Solution PDF.
