When it comes to the axis of a circular or cylindrical object, you will find these two terms “coaxiality” and “concentricity”. If you are an engineer, you denenitely have to know about them. For those who are looking to find how they differ, this post may help you a little bit Coaxiality The coaxiality is … Read more
Wondering how roundness and circularity are different? Or both are actually the same? How to express them in terms of tolerance? We’ll be discussing it here. Roundness In simple words, the term roundness is defined as a value that is used to compute the errors that appear in a perfect circle. In other words, roundness … Read more
Both repeatability and reproducibility are important in measurement and research. If you are the operator of a particular precision measuring instrument, you have to know these two terms. Your instrument has to be repeatable. It means you take several readings and you get the same readings. If there is a variation, then you have to … Read more
You may be hiking and seeing the altitude reading on your altimeter device. But somehow, the term elevation pops up in your mind, and you realize that they are almost the same and do not know how to distinguish them. If you are wondering what actually altitude and elevation mean, then this page may help … Read more
Flatness and surface profile lie in two different fundamentals of GD&T (out of a total of four) namely, flatness is categorized as “form”, while the surface profile is categorized as a feature of “profile”. All “form” features are used for individual features; which is why they don’t require a datum for their complete definition. The … Read more
Sometimes, it’s not easy to differentiate between squareness, perpendicularity, and parallelism. They are almost the same and have a close correlation. Even, squareness and perpendicularity are frequently used interchangeably while in fact, they are actually different. On this great occasion, we are glad to present an article that covers the explanation of these terms. Differences … Read more
Are you building a flat and level desk for your project? Do you need a flat floor but have a little slope on it? Or need a flat floor with a perfect level? Do you want to build a kitchen cabinet that is flat and level? The two terms flat and level are considered the … Read more
In physics, we frequently come across confusing terms, which may require further attention to understand for some people. Some of those terms are distance and displacement. Actually, these two terms are used to express length. But in physics, it’s too rough to say length. Therefore, the term “length” needs to be detailed. In our life, … Read more
A spectrum analyzer and a network analyzer are both important pieces of testing equipment and instrument for an engineer. Although they sound similar, however, they pose some major differences. In this article, you will be having a close look at how each device works and what differentiates them from each other. What is a Spectrum … Read more
In engineering, the requirement to know what to measure on a day-to-day basis is essential. You have to know what to check for all shapes, sizes, and axes, including spherical or cylindrical. While doing those jobs, it means you are going to measure runout and total runout. It is usually noted for parts or components … Read more
