By: SANS Machining In this article, we will discuss different types of coordination in engineering. After reading this article, you will understand what fits are and the types of fits used in mechanical engineering. What Is An Engineering Fit? Engineering fit is a mechanical assembly in which two mating components are permanently or temporarily connected together. The term 'fit' refers to the amount of mechanical clearance or physical contact between mating components. Fits are based on shafts or holes. The hole is whether the internal feature of the part is cylindrical, while the axis is whether the external feature of the part is cylindrical. For hole based systems, the size of the hole remains unchanged while changing the axis to determine fit. On the contrary, it applies to shaft based systems where the shaft size remains unchanged, and the hole size will change to determine the fit. Please note that CNC turning services (https://www.sansmachining.com/ If the part fits closely and the joint can bear the load, it is a interference fit. On the other hand, the characteristic of transitional fit is that the joint bears sufficient force to maintain contact but cannot withstand high loads. The third type, clearance fit, has a small gap between the mating components that allows them to rotate or slide freely. Types Of Fits There are various types of commonly used combinations in engineering applications. Choosing the appropriate fit for a specific application depends on the required accuracy and the magnitude of the force or load to be applied. Clearance Fit Clearance fit allows for loose fit, where free movement is important and requires a certain amount of clearance. We see that the gap fit requirement elements should be able to slide in and out without obstacles, and can be loosely guided for alignment without requiring strict accuracy. Examples of clearance fits may include bolts/shaft holes, where one component can freely slide through another feature. Due to this clearance, the parts in the clearance fit have a certain degree of freedom (motion). For example, the pin and frame in the pivot joint use a clearance fit, allowing the two components to move independently of each other while maintaining locking in place.
