The Basic Overview of How CNC Machining Works
1. Design: A part is first designed using computer-aided design (CAD) software. This digital blueprint outlines the dimensions and specifications of the final product.
2. Programming: The CAD design is then translated into a machine-readable format using computer-aided manufacturing (CAM) software. This program generates a set of instructions, known as G-code, which tells the CNC machine how to move and operate.
3. Machining: The CNC machine uses the G-code to control its movements. This could involve cutting, drilling, milling, or turning operations. The machine's tools follow the precise paths and specifications dictated by the program to produce the part.
4. Finishing: After the initial machining, the part might undergo additional finishing processes such as sanding, polishing, or coating to achieve the final desired quality and appearance.
