Hole Basis System and Shaft Basis system – In the Machine design process there are different components are mated together to make the machine. These components will have a different function. Base on their type of functions there must be the type of fits between the two mating components should be determined. How actually can a […]
Metrology is a science of measurement. It meant to understand the units of each quantity and the realisation of the units and calibration. In each country, they follow different unit systems, among them, the Metric system is the predominant system in the world. In this article, we have listed all the different Metrology topics that we have discussed so far.
Based upon the field of application Metrology can be further divided into
- Industrial metrology
- Scientific or Fundamental metrology
- Legal metrology
see what are these different metrology types here.
Types of Fits In Engineering-In mechanical engineering, Mating of two components is to be determined based on the function of the two components. Even though the fasteners make them tight but tightness between the two surfaces may be needed high in some applications wherein other applications it is not required to be that much tight. So […]
In mechanical engineering System of limits or Limit System is a concept of controlling the sizes of machine elements while manufacturing of each component. Because taking exact dimensions is an ideal condition but in practical(Manufacturing/Measuring) methods, it is not possible. So limit system enables how much amount of deviation is acceptable. How do we apply the limit system […]
Topic: What is Interchangeability in Machine Design? | interchangeable parts | In Machine Design Interchangeability represents to the interchangeable parts. So what are the Interchangeable parts? A machine is a combination of several components. If any of the components is failed or broken then the part needed to be replaced with the new component. This new component should be […]
Topic: What are the different Flatness testing methods for Surface Plates? The surface plate is a massive solid structure, highly rigid in design which is having a true flatness of the surface. In metrology, the Surface plate is used as a measuring base or a datum surface for testing of flatness of surfaces. Surface plate forms the […]
