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
Do you want to check how straight or flat a surface is in either vertical (plumb) or horizontal (level) planes? Also maybe you’ve been asked to test both but are unsure where to start? Take it easy because this article is about to discuss being plumb vs. being level. And hopefully, it will help shed some … Read more
Are you struggling to decide which one to buy among the protractor, inclinometer, and angle cube? Is it a little confusing in what situation they are excellent? In other words, in what application are each of them used to? What is actually a protractor? Why are many tools named protractors? Does it go the same … Read more
Maybe, you need to check how square an object is but are not sure how to do that. If you need an object to be square, accurate and uniform, it is essential to know how this can be checked and even measured accurately. This article will inform you briefly on how to measure squareness with … Read more
Do you want to check how square a block is but are not sure what squareness exactly is? Maybe, you also want to know how to express the degree of squareness in number. Aside from that, you are wondering whether there is something exist a perfect square. We will be discussing about them all here. … Read more
Tolerance and allowance may be frequently understood as the same thing for some people. This is not weird because these two terms have a great relation in defining the limits of a dimension. Basically, tolerance and allowance are used to describe the limits of an object dimension so that the dimension is acceptable for mechanical … Read more
Gauge blocks are a set of precision-cut stable metal blocks of different thicknesses used as a length standard. They usually come in a set, but you could also find them individually. Measuring instruments such as micrometers, digital calipers, vernier calipers, dial calipers, height gauge, dial indicators, and test indicators use gauge blocks for inspection and … Read more
Communication is an activity that everyone does daily. To communicate is to send (transmit) or receive the data (information) between two or more sides. In the electronic world, communication is done in certain ways. The protocol regulates it. A protocol consists of a set of rules that ensure a secure and reliable communication process. In … Read more
Calibration is to find out the measurement error. According to the measurement error that is observed, verification is to decide whether it is within the tolerance (permissible error) or not. Then, validation is to make sure it measures what it’s meant to. In some cases, verification and validation overlap. Calibration According to NIST, calibration is … Read more
Gauge blocks or slip gauges or Jo-blocks are used for calibration, inspection, and verification. They function as standards. According to its grade level, they can be a reference or working standard. Therefore, you could find gauge blocks in the area of the workshop and calibration lab. The role of gauge blocks is highly vital in … Read more
