Here are the steps involved in CNC machining aluminum:

Design: The first step is to create a CAD (Computer-Aided Design) model of the desired part. This design serves as the blueprint for the CNC machine to follow.

Programming: Once the design is complete, the next step is to program the CNC machine. This involves converting the CAD model into machine-readable code, which determines the toolpath and coordinates for the machine to follow.

Set up the machine: The aluminum block or sheet is securely mounted on the CNC machine's table or chuck. The cutting tools are also installed and properly aligned.

Machining process: The CNC machine is started, and the programmed code is executed. The cutting tools rotate at high speeds and move along the programmed path, removing aluminum material to create the desired shape.

Tool changes: Depending on the complexity of the part, multiple cutting tools may be required. The CNC machine automatically changes the tools as needed during the machining process.

Finishing touches: Once the initial machining is complete, additional processes like sanding, deburring, or polishing may be done to achieve the desired surface finish.

Quality control: The final part is inspected for dimensional accuracy and quality. Measurements are taken using precision measuring tools to ensure it meets the specified tolerances.

Advantages of CNC machining aluminum include its low weight, high strength, corrosion resistance, and good thermal conductivity. It is commonly used in various industries, including automotive, aerospace, electronics, and more.
