Here are some key steps involved in CNC milling aluminum:

Designing the part: Use CAD/CAM software to design the part or import a pre-designed model.

Material selection: Choose the appropriate grade of aluminum based on the specific requirements of the part, such as strength, weight, conductivity, or corrosion resistance.

Fixturing: Secure the aluminum block to the CNC milling machine using clamps or a vise to ensure stability during the machining process.

Tool selection: Select the proper cutting tools based on the part's geometry, desired surface finish, and material properties. Common tool types for aluminum milling include end mills, ball mills, and face mills.

Machine setup: Input the part specifications and cutting parameters into the CNC machine's control software, such as feed rate, spindle speed, and depth of cut.

Machining: The CNC machine will move the cutting tools along the programmed tool paths to remove material from the aluminum block, creating the desired shape or part.

Quality control: Inspect the machined part for dimensional accuracy, surface finish, and other quality criteria using measurement tools such as calipers, micrometers, or coordinate measuring machines (CMM).

Finishing operations: Depending on the application and part requirements, additional post-machining processes may be performed, such as deburring, polishing, or anodizing.

Overall, CNC milling aluminum offers precision, efficiency, and repeatability, making it a popular choice for manufacturing high-quality aluminum parts.
