Mainstream Hardness Scales and Their Conversion
Hardness is a measure of a material’s resistance to localized plastic deformation, such as a dent or a scratch. Unlike properties such as mass or length, hardness is not a fundamental property but is defined by the method of measurement. Consequently, there are numerous hardness scales, each suitable for different materials and applications. Direct conversion […]
Profile Milling
If you want to create complex shapes on your workpiece material, then profile milling would be your go-to. This is because it uses a tool that has multiple cutting edges, which can cut the material along the side or angle according to your desired pattern. Also it has ball tip that moves around to smooth […]
The Yield of a Metal Component
The “yield” of a metal component is a fundamental mechanical property that defines the transition point from elastic to plastic deformation. Understanding this point is critical in engineering design, material selection, and failure prevention. 1. Fundamental Concept: The Stress-Strain Curve The yield behavior of a metal is most clearly understood from its Engineering Stress-Strain Curve, obtained from a […]
Angle (Angular) Milling
On the other hand, in angle milling, you use the specialized milling cutters like tapered one that are flare or cone-shaped but can be adjusted to the desired angle. So, here, you would actually place such cutter at a specific angle relative to the workpiece (not parallel, not perpendicular). So, when the cutter rotates, it […]
Chrome Plating
Chrome plating, also known as chromium plating, is an electroplating process that involves applying a thin layer of chromium onto a metal or plastic object. The result is a surface that is highly valued for its aesthetic appeal, hardness, and corrosion resistance. There are two primary types of chrome plating: Decorative Chrome (Nickel-Chrome): A thin, bright, […]
Slot Milling
As the name suggests, you can use the slot milling operation to carve a channel of any size in the material, which you say like grooves or slots. You can do this job with a slot cutter, which basically looks like a circular saw blade, allowing you to cut the sides of material from the […]
A Comprehensive Guide to 3D Printing Materials
The world of 3D printing has evolved far beyond basic plastics. The choice of material is now critical, as it directly impacts the strength, flexibility, appearance, and functionality of a printed object. Materials are generally categorized by the printing process they are designed for. Here’s a detailed breakdown. 1. Fused Deposition Modeling (FDM) Materials FDM […]
End Milling
End milling is the most versatile milling operation among all, as the cutter used has actually cutting edges on both ends or sides. Thus, you can use it to produce pockets, slots, or even contours in the workpieces. Well! You can imagine it like a drilling machine, but the difference is that a drilling machine […]
Peripheral (or Plain) Milling
If we talk about the peripheral milling, then you can say it’s the opposite of the face milling. This is because, unlike face milling, here the cutter is placed in an axis parallel to the workpiece. As a result when the cutter rotates then it would actually remove material from the sides or edges of […]
Reduction of Area (RA): A Measure of Material Ductility
The Reduction of Area (RA) is a fundamental, quantitative measure of ductility obtained from a tensile test on a material specimen. It expresses the extent to which a material can plastically deform (i.e., stretch) in a localized region before it fractures. 1. Definition Reduction of Area is defined as the percentage decrease in the cross-sectional area of a tensile […]
