Shinta The degree of how an object is exactly like a square shape is squareness. It has a correlation with straightness, perpendicularity, parallelism, and 90-degree angle. And we express squareness in a tolerance value. One of the prevalent shapes used as a reference for geometric conformity of squareness is a square tool. However, there are many … Read more
Among the tools available to measure an angle, a protractor (or engineering protractor) is a simple mathematical and geometrical instrument used for drawing, measuring, and plotting angles. Protractor has a scale that is graduated in angular unit degree, on its outer most circular edge and has a vertex mark right at its center of its … 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
Recognizing the feeler gauge types can help you decide which feeler gauge is best for you. There are several models of feeler gauges that you should know. Picking the right one can solve your job easier. There are straight, tapered, dual graduation, offset, strip, brass, and go-no-go models. 1. Straight Feeler Gauge This is the … 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
Square tools are easy to find in the workshop whether it is a machinist or woodworking workshop. It functions mainly to check the squareness, perpendicularity, and right angle (90-degree angles). Nowadays, squares are used for marking, scribing, framing, drawing, etc. That’s because the square helps scribe lines either perpendicular or parallel to the edge of … Read more
The surface plate serves as a baseline, a reference point, or a datum point for linear measurement and dimensional inspection of objects, mechanical parts, and industrial parts. It is commonly used in an inspection lab of a manufacturing site. It is a must for any metrology laboratory to have this tool that is used for … 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
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
