Gauge blocks come with a purpose to serve as a reference standard for length. We use them whether in lab or workshop. Dimensional measuring instruments such as micrometers (outside, inside, and depth micrometers), calipers (both the vernier, dial, and digital caliper models), indicators (both dial and dial test indicator), and height gauge benefit from these … 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
A try square is one of the woodworking square models (combination square, speed square, etc) that you have to own in your toolbox. Whether in woodworking or carpentry projects, you will find this tool very helpful to generate a neat working result. The primary function of a try square is to check whether an object’s … 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
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
Learning about how to read a dial caliper is about learning how to read its main and dial scale. The main scale is linear like the ruler, while the dial/secondary scale is circular. Simply, if you ask how to read dial caliper, you have to master these two scales. There is an imperial or metric … Read more
Reading a digital caliper is easier compared to reading a vernier caliper or dial caliper. It automatically displays the reading on the LCD screen. So, there is no need to calculate the main and the secondary scale. It requires less time and effort to read the measurements. Although it’s easier, when it comes to how … Read more
Reading vernier caliper takes more steps than reading dial caliper or reading digital caliper. The users have to manually calculate both the scales (the main scale and the vernier scale). Vernier scale calculation, especially, is the contrasting thing when compared to reading those two types of caliper. Your eyes have to be careful when deciding … 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
