What is the CNC Machining?

CNC (Computer Numerical Control) Machining is a manufacturing process that uses computer numerical control technology to control machine tools for precision machining. Pre-written CNC programs control tool movements and cutting, able to create complex geometry from metal, plastic, and wood. Aluminum profile manufacturers often use CNC machining to produce high-precision and intricate parts.

What are the Steps in the CNC Machining Process?

Every step in the CNC machining process is crucial to producing high-precision, intricate components. Shall we continue with more details?

Computer-Aided Design (CAD)

CNC machining starts with creating a 3D model using CAD software. Customers provide product design files (CAD drawings), and engineers use those to generate numerical control programs that define the part’s geometry and machining path.

Computer-Aided Manufacturing (CAM)

After the design is complete, CAM software (Mastercam or Fusion 360) converts CAD files into machine code (G-code) that the CNC machine can understand. This code includes tool movement paths, speeds, feed rates, and cutting depths.

Choose the Right Tools and Materials

Based on design and material, the right tool types and materials are selected. Common tools are milling cutters, turning tools, and drill bits, and materials are aluminum, steel, stainless steel, and plastics.

Machining Operations

CNC machines run the program automatically. Common CNC machining operations are:

• Milling: Rotating tools cut material, good for planes, slots, holes, and complex shapes.
• Turning: Rotating the workpiece while cutting tools shape surfaces, good for round or cylindrical parts.
• Drilling: Drilling holes in material surfaces.
• Tapping: Threading pre-drilled holes.
• Cutting: Precision cutting with saws or cutting tools.
• Electrical Discharge Machining (EDM): Cutting through complex or hard material with electrical sparks.

Inspection

After machining, inspection equipment (CMM) checks part dimensions, surface roughness, and other criteria to ensure design requirements are met.
