Do you need to see the Drill and Tab chart right now? Jump to Tab Drill Chart. Taps are cutting tools used by machinists to cut or form screw threads. The first recorded use of taps in metalworking is placed sometime in the 18th century, while the British engineer and industrialist Joseph Clement popularised the …

As the name suggests magnetic bearings use magnetic levitation to support the rotating shafts, without directly contacting them, thus there is no friction. As we all know, less friction means less energy wasted and greater overall efficiency. The very first patent relating to the magnetic suspension of rotating elements was submitted in the 1940s. However, …

In simple terms, the melting point of steel for example, is the temperature when it starts to change from a solid state to a liquid. At this specific melting point temperature both phases of the substance exist in equilibrium. Therefore, further heating needs to be passed through the substance to complete the transition from solid …
The Taylor Functions are series of sum terms that concern the values of the derivatives of a given function at a given point, so they are a part of Calculus. They are a clever practical way to expand and simplify complicated and transcendental functions into computable polynomials. The number of the sum terms that are …

The surface roughness chart is a concept that expresses the amount and extent of deviation of a surface from being perfectly flat. As it is practically impossible to manufacture a completely flat surface on the microscopic level, every surface has a certain value of roughness that can be measured with the use of a profilometer. …
Defining and understanding the basic structural concepts of engineering and how they are expressed in physics and mathematics is a key aspect for students. This enables them to enter the realms of structure design and development on the right foot. The purpose of this quick guide is to provide a generic yet helpful description of …

Any mechanical design engineer who designs enclosures MUST have a firm grasp of IP ratings. IP stands for “Ingress Protection” and is a standard protection marking for casings and enclosures of electrical and electronic products. It helps to classify them according to their degree of protection against solids and liquids. The standard IP ratings were …

The harmonic drive is a type of gear arrangement often referred to as a strain wave gear because of the way it works. It is a kind of reduction gear mechanism consisting of a minimum of three main components. These components interact in a way that allows for very high precision reduction ratios that would …

The centrifugal clutch is a clutch that bases its operation on the principle of centrifugal force generation. It is generally considered one of the smoothest types of clutches as it engages the load to the engine gradually, allowing the engine to reach its optimal torque range before it has to carry any loads. This is …

It is the 6061 aluminum properties that make it one of the most widely used aluminum alloys, being applied in various fields since 1935. A member of the “6000” alloy series, it typically consists of 97.1% aluminium, 1% magnesium, 0.7% iron, 0.5% silicon, 0.3% copper, 0.2% chromium, 0.1% zinc, 0.05% manganese, and 0.05% titanium. 6061 Aluminum …
A profilometer is a highly specialised meteorological measurement device that is used for the determination of the roughness of a surface. As a measurement instrument, the profilometer is very precise as it is expected to have the capacity to identify and quantify very small-scale surface features. The roughness of a surface is categorised in grades …
Compression springs are mechanical devices that are specifically designed to be induced to axial compression loads. They can usually also be extended as well as rotated up to a point. In general, compression springs can store mechanical energy when a compression load is applied to them. They will return back to their original shape and …

Pipes are extensively used in mechanical engineering, from the Oil & Gas industry and their offshore rigs to the more simplistic home tap water networks, these hollow sections made of metal or plastics are essential for a very wide spectrum of applications. Before we head into the details of their standardization, it is important to …
Thermal engineering is one of the most fundamental areas of mechanical and chemical engineering, with the study of heat transfer being one of the most significant disciplines. Heat is energy, so heat transfer is practically energy transfer that takes place in small scale but affects large systems such as renewable energy harvesting units, industrial cooling …
While there are many materials which are tough and long-lasting and others which are malleable it is difficult to find materials which have all of these characteristics. This is why maraging steel is so important in the world of mechanical engineering and why it plays a major role in our everyday lives. What is Maraging …
Transparent wood is a type of a composite material that has the potential to revolutionise the fields of construction and the manufacturing of various products. It combines the benefits of wood as a material and the achievement of making it opaque. For now, transparent wood remains under development but advancements in the science of materials suggest that …
