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
A T-square is a type of square tool to scribe a perpendicular line on a working surface (wood, paper, etc) that starts from its surface edge (not the corner). Although it’s a square tool, its main purpose is not for checking the workpiece’s corner like the try square and speed square do. This tool is … Read more
One thing you have to always keep in mind when using a dial indicator is the angle that it shapes to the surface must be 90°. In other words, the plunger and the surface being measured must be perpendicular. This angle is important in order to obtain correct measurement results and prevent cosine error. Though … Read more
A digital indicator is the electronic type of dial indicator. This model is excellent in terms of speed. Instead of reading the two scales, a digital indicator allows you to read the reading instantly on the screen which lets you quickly know the measurement result. You don’t need to manually read the smaller and the … Read more
Dial bore gauge allows you to measure the internal diameter of a cylinder hole with better speed and accuracy compared to the telescopic model. As the name suggests, it comes with a dial indicator to display the reading in real-time. The long shaft lets you reach the internal diameter down the deeper area. Since it’s … Read more
An altimeter is an instrument to measure altitude; the vertical distance between the altimeter and mean sea level. Please remember that altitude, elevation, and height are different. Altimeters can come in a watch (altimeter watch). This model is appropriate to use for hiking, mountain climbing, etc. This watch can be also equipped with a GPS … Read more
Accuracy and simplicity are two priority things in metalworking. And that’s why designers and engineers use varieties of measuring tools in workshops. There are a lot of tools we might need to design our complete model. And thus, we are here to summarize each of the tools we might need in metalworking workshops. In each … Read more
Vernier caliper is the type of caliper that makes use of a vernier scale to display the reading. This vernier scale can provide you with a resolution of .001″ (0.02 mm). It is common to find a vernier caliper with a 6″ measuring range. But you can also find the longer ones such as 8″, … Read more
