CNC Machining Overview

What’s CNC Machining?

CNC Machining, or Computer Numerical Control Machining, is a manufacturing technique where computer-controlled devices are used to remove layers from a material, creating detailed parts or components. Through a combination of tooling and precise machine movement, it produces parts to exact specifications.

What’s the CNC Machining Process?

The CNC machining process begins by designing a part in CAD software. This design is then converted into a set of machine commands using CAM software. The CNC machine reads these commands to precisely cut and shape the material, producing a finished part that matches the digital design.

Why Choose CNC Machining?

CNC Machining offers unparalleled precision and repeatability, making it a top choice for industries requiring intricate parts. Its ability to handle a variety of materials, from metals to plastics, combined with fast production times and consistent quality, makes it an essential method in modern manufacturing.

What’s the Difference Between 3D Printing and CNC Machining?

3D printing is an additive manufacturing method, building parts by depositing material layer by layer. In contrast, CNC machining is a subtractive method, starting with a solid block of material and removing sections until the desired part is achieved. While 3D printing is often favored for complex geometries and rapid prototyping, CNC machining excels in durability, precision, and material versatility.

What services does RapidDirect provide in sheet metal fabrication?

RapidDirect offers a comprehensive range of services including cutting, bending, punching, welding, and assembling. Our state-of-the-art machinery ensures precision and high-quality finishes for all projects.

Sheet metal fabrication tolerances refer to the acceptable deviations for features of sheet metal parts required for accurate and consistent installation and integration.

For sheet metal parts, ISO 2768-mk is usually used to ensure proper control of the elements of geometry and size. The following will show you 7 tolerance standards range of linear and angular dimensions, flatness & straightness, cylindricity, and circularity.

K factor is the sheet metal process is the ratio of neutral axis to material thickness. This value changes with respect to the various physical properties and thickness of materials used.

Every aspect of a sheet metal fabrication project comes with an associated cost — the design, possible prototype, finishing processes, and others. Asides from the process itself, materials also cost money. To learn some tips for reducing custom sheet metal fabrication costs,

AL Aluminum accommodates both small and large production runs, from single prototypes to mass production, with no strict minimum order quantity.
