CNC prototyping uses computer-controlled machines to make precise prototypes from digital designs. These machines carve out shapes from materials like plastic, metal, or wood based on the design. Starting with a digital model, the CNC machine follows exact instructions to create the prototype, ensuring high accuracy and intricate details.
Unlike traditional prototyping methods, CNC rapid prototyping allows for iterations within days. This process speeds up product development by allowing quick testing and adjustments before making the final product. Industries like automotive, aerospace, medical and electronics use CNC prototyping to test concepts, refine designs, and ensure quality before mass production. It’s a vital step that brings ideas to life, improving products and meeting high standards.
CNC parts could cost from as low as $100, or as high as $1000 or more. The price depends on the material, tolerance, machining hours, geometrical complexity, part size or quantity.
The two primary CNC machining processes are CNC turning and CNC milling.
Many industries rely on CNC machining for high-precision parts and prototypes, including:
For features left unspecified, standard tolerances are used. The standard machining tolerance is ISO 2768 Fine (F) for metals and Medium (M) for plastics. Tighter tolerances are available on request.
What is 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. The CNC machine reads these commands to precisely cut and shape the material, producing a finished part that matches the digital design.
What are the advantages of 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 is 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.
