The ability of a material to resist permanent indentation is known as hardness. It is an empirical test, rather than material property. In order to define different hardness values for the same piece of material, there are several types of hardness tests. The outcome of each test should have a label identifying the method used, as it is dependent on it. There is no intrinsic significance of hardness value or number, hence it cannot be used directly like tensile test value. The value is only useful for comparing different treatments or materials.

The world of industrial maintenance is hectic, demanding and intensive. Even when working in the world of metrology, it can be hard to understand the differences between alignment, balancing and vibration. In this post, we will provide you an in-depth overview of each term and what role they play to ensure the health of your equipment.

Torque is a type of force that tends to cause rotation. It is one of the most important mechanical quantities in many industrial applications. Precise measurement of the torque on rotating sections, placing high demand on test bench users and manufacturers. There are a couple of ways to determine torque:

CT scanning technology can inspect the interior structure of the injection forged, molded or cast parts made from composites, polymers, plastic and metal products, without causing any damage to the objects. Seeing through a solid object was once a fantasy, but the technology of computed tomography imaging has made it possible. It is now being used in various industrial metrology settings for packaging integrity and product evaluation.

It can be a daunting task to choose the right inspection system for your application. Three types of inspection systems are generally employed for industrial applications. Let us a take a look at each one of them, along with their merits and demerits.

Strain measurement is capable of resolving one PPM (one part in a million) or more. This is because of the exacting controls and standards under which each strain gage is manufactured. Some of the principal measurement errors arise from the manner in which the strain gage sensor is installed and measurement is taken. Let us take a look at some of these.

The science of measurement is known as metrology and the application of its principles plays a pivotal role throughout production process in CNC machining. This is done to make sure that each and every part is machined to the right shape and size.  Measuring dimensions of a CNC machine part with tight tolerances can be difficult. Depending on the quality, quantity and the type of work they do, there are distinct set of metrology tools in every CNC machine shop. Here are a few you should have, if you are an owner.
