In woodworking, to measure the dimensions of different parts which are to be crafted or joined together, different tools are used. To check of the two meeting surfaces whether they are perpendicular to each other, squares are used. These square tools commonly consist of two blades that are fixed perpendicular to each other. The angle … Read more
There are several reasons why the depth micrometer is superior to the depth caliper. But, vice versa, there are also several points that the depth caliper is better than a depth micrometer. On another page, we discuss the difference between a micrometer and a caliper. But, it seems not a complete comparison, not specifically comparing … Read more
The reliability of handheld tools like calipers is frequently required in many areas that need higher accuracy and precision such as in engineering, metrology, manufacturing, quality control, 3D printing, etc. However, behind its advantage, these measuring tools are important to keep them well maintained to give accurate readings with extended life. The care includes regular … Read more
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
The handling and general storage of measuring tools and equipment are important for maintaining their accuracy. It includes the feeler gauge, a simple tool that comes commonly in a set consisting of several blades of different thicknesses. According to the ISO 17025 standards, the feeler gauge equipment in laboratories and industries is to be kept … Read more
Dial indicator is a precision measuring tool that has many functions. Its application is to measure tolerance, allowance (including clearance), circular runout, total runout, straightness, flatness, parallelism, perpendicularity, squareness, circularity, cylindricity, levelness, etc. Therefore, this instrument is easily found in the workshop and becomes a critical part to monitor the quality of product dimensions and any … Read more
As we know that dial indicator is one of the most important measuring apparatuses in mechanical industries. We apply this precision instrument to check the runout between the workpiece surface and axis of rotation, clearances (distance between two surfaces), straightness, and many other tests. Every dial indicator component has its own importance. But the most … Read more
Cosine error occurs in the dial indicator when the direction of measurement of an object is at a certain angle (not as it should be) against the tip of the dial indicator. As the angle increases, the value of cosine error also increases. This error is small in value but it’s considerable when we want … 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
Caliper is one of the most common inspection tools, hand tools, and measurement equipment in workshops. This tool should provide accurate reading and help provide accurate measurement for the dimensional measurements of any parts, components, and products being manufactured, fabricated, and hand-made. During the frequent use of this measuring instrument, it might easily wear. If … Read more
