We regularly update articles related to the manufacturing industry.
OEM stands for Original Equipment Manufacturer, and ODM means Original Design Manufacturer. OEM focuses on producing items based on a buyer’s design. ODM, on the other hand, develops products from its designs and sells them under another company’s brand. Both approaches help businesses bring ideas to market, but differ in control, cost, and flexibility.
Offset machining is making small changes to the tool’s position in a CNC machine to improve how a part is made. These changes, or “offsets,” adjust the path or depth of the cutting tool during the machining process. They are applied through the machine’s control system, without changing the original G-code program.
Subcontract machining is when a company outsources part of its manufacturing work to an external machine shop. These shops focus on cutting, shaping, and finishing metal or plastic parts to precise specifications.
Brushed aluminum has been mechanically polished to create a dull, consistent grain. This grain runs in a single direction, making the surface matte. The brushing removes small imperfections and gives the metal a sleek, modern look.
Tool steel machining means cutting, drilling, or shaping tool steel into a specific part. This can be done with CNC machines or by hand. Tool steel is a carbon and alloy steel made to be very hard and resistant to wear. It can also keep a sharp edge. Common grades include D2, O1, A2, and M2.
Titanium stamping is the process of pressing flat titanium sheets or coils into specific shapes using dies and high-force presses. The stamping process can include steps like deep drawing, blanking, bending, embossing, or piercing, each helping shape the metal into the final part.
True Position is the exact location of a feature, such as a hole, pin, or slot, as defined concerning datums. Simply, it tells us where a feature should be placed on a part. Instead of focusing on the exact X and Y values, it defines a zone—usually a circle or cylinder—within which the center of the feature must fall.
ABS plastic machining is the process of shaping ABS (Acrylonitrile Butadiene Styrene) into finished parts using tools like mills, drills, and lathes. ABS is a thermoplastic. It is strong, impact-resistant, and lightweight. It comes in sheets, rods, or blocks. You can cut, drill, or turn it into parts with basic machining tools.
Backstep welding is a method where the welder works in short sections, moving in the opposite direction of the overall weld path. For example, if the finished weld runs from left to right, each small segment is welded from right to left. The new bead overlaps slightly with the previous one.
When picking a material for CNC milling, you need to know your design’s needs, the part’s job, and your budget. Think about strength, machinability, cost, and how the part will be used. Then match those needs to what each metal or plastic can do. Good material choices save you time, money, and trouble.
Thread tapping is cutting threads inside a hole using a tap. The tap has cutting edges shaped to match the thread profile. As it turns into a drilled hole, it removes grooves to form a threaded path.
Spring steel stamping is a process that uses a press and a matched die set to cut and shape thin sheets or strips of spring steel. The die applies controlled pressure and movement to form the material. This process can perform several operations, including blanking, piercing, bending, coining, embossing, and drawing.
Blow molding is a plastic-forming method. It starts with melting plastic and forming it into a hollow tube called a parison. This parison is then placed in a mold. Compressed air is then blown into the parison. The air pushes the plastic outward, and it takes the shape of the mold. Once cooled, the mold opens, and the part is removed.
Taper turning is the process of cutting a surface that gradually changes in diameter along the length of a round workpiece. It forms a cone-like shape using a lathe. The taper can be on the outside (external) or inside (internal) of the part. The angle and length of the taper are based on what the part is used for.
Circular runout controls variation at each circular cross-section. Total runout controls the entire surface across the length. Circular runout focuses on roundness at one spot. Total runout adds straightness and taper checks across the whole feature.
Sheet metal drawings are technical documents that show a part’s size, shape, and key features. They often list material type, thickness, and finish requirements. Depending on the project, these drawings can be in 2D or 3D. They provide precise cutting, bending, welding, and finishing instructions.
