What does the acronym FN represent in machining?

• A. Force fit
• B. Free normal
• C. Finished number
• D. Fixed net

Answer: (A)

In machining, the acronym FN stands for "Force fit." This term refers to a method of joining two components together such that they are held in place by high levels of friction and interlocking surfaces, eliminating the need for additional securing means like bolts or welds. A force fit is particularly useful in applications where components need a robust connection capable of withstanding significant stress without the risk of loosening over time. Understanding force fit is crucial in machining as it relates to the precision and accuracy of component assembly. When parts are designed to fit tightly together, engineers must consider tolerances, material properties, and manufacturing processes to ensure that the force fit achieves the intended mechanical performance. The other options, while related to machining terms, do not accurately represent the acronym FN specifically. Each has its own context in the engineering and manufacturing fields, but they do not align with the common usage of FN in the context of machining practices.
