In Metrology, The angular measurements are frequently necessary for manufacturing industries. Vernier Bevel protractor is one of the angular measuring instrument used for close tolerances. We are going to discuss the construction and the working principle of the Vernier Bevel protractor in this article. Vernier Bevel Protractor Bevel Protractors are the Angular measuring devices. Vernier Bevel […]
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.
Angle is a measurement that we can measure between the two line which meets at one point. Angular measurements are playing a very crucial role in measurements. The best example is that the Ships and the Aeroplanes will navigate with the help of The precise angular directions of the landing area. Let’s discuss Angular Measuring Instruments. […]
In Mechanical Engineering Surface finish and the surface roughness, both are referred to same. But In general Surface finish referred as the overall texture of the surface and it is a combination of three factors. Those are surface roughness, Surface waviness, Lay. Little Confusion? Let’s get into the topic Make it Clear. We produce Machine elements […]
In machine Design, each machine member will be mated with another machine member with the defined fit. There are the different type of fits available. They are Clearance Interference, Transition fits. These fits are controlled with some Tolerances and allowances according to some Standards. Actually, these tolerances values can be calculated. According to Indian Standard […]
Fundamental Deviation of shaft and holes– Fundamental deviation is an allowance rather than tolerance. The allowance is simply the deviation between the hole minimum diameter to the shaft maximum diameter. Where the tolerance refer to either hole (Max. dia of hole-Min. Dia. of the hole) or shaft (Max. Dia. of the shaft- Min. Dia. of […]
