Aluminum CNC machining helps to meet the stringent quality standards for precision and reliability in the aerospace industry. CNC-machined aluminum parts play pivotal roles in producing aero-structures like wing panels and fuselage sections.

To sum up this tip: Don’t remove large amounts of material after hitting final dimensions; titanium warps like crazy. Do your roughing first, and creep up on tight tolerances.

You might already be familiar with some of these challenges, especially if you’ve dealt with thin aluminum or stainless steel. For titanium, though, expect even more warping.

Aluminum 1xxx alloys comprise the highest pure aluminum content, with about 99% aluminum by weight. There is no particular alloying element; most of these alloys are almost pure aluminum. For instance, aluminum 1199 contains 99.99% aluminum by weight, which is ideal for making foil. Although these grades are the softest, you can harden them to make them stronger when continuously deformed.

Thin titanium parts usually need to be roughed on both sides, then unclamped, then finished. Creep up on finished dimensions to ensure that you can hold tight tolerances.

CNC machining processes create constant chip load, considered waste materials since it’s a subtractive process. However, aluminum is highly recyclable; as a result, it requires cost, effort, and minimal energy to recycle.

Aluminum CNC machining is amongst the top machining operations in terms of frequency of execution due to the material’s remarkable machinability. Manufacturers rely on aluminum CNC machining to make different precision aluminum parts that meet the intended applications’ requirements. The process involves using CNC routers to shape aluminum material into preferred shapes and dimensions.

Heat doesn’t dissipate quickly with titanium. Actually, compared to most other metals, titanium is a thermal insulator more that a conductor.

Besides, high-end audio equipment such as amplifiers, headphones, and speaker enclosures often house aluminum CNC machined parts. Aluminum is commonly used in this application since it can dampen vibrations. Also, aluminum CNC machined parts offer the desired strength and can dissipate heat in devices like cameras.

More importantly, use tools with sharp cutting edges and right rake angles to reduce friction. You can also check the cutting tools frequently for signs of wear and replace worn tools immediately to prevent workpiece damage.

The presence of silicon in some aluminum alloys may make aluminum machining abrasive. As a result, you may experience rapid tool wear and consistent tool changes during aluminum CNC machining.

Common problems include chipping and notch wear at the “skin” of the cut. Insert geometry and grade can have a huge impact on tool life and process stability. For example, consider using a WNMG instead of a CNMG insert.

Aluminum CNC machining is a widely embraced product manufacturing process thanks to the unequaled potential of aluminum alloys. The alloys of aluminum have further improved aluminum’s characteristics and properties, making CNC aluminum machining an ideal manufacturing process.

Tools also don’t like being buried in corners. Even for turning, programming an arc interpolation and using a tool with a smaller nose radius will likely give better tool life than burying the tool fully at a step. This is especially critical for finishing toolpaths.

Tooling reps are usually always wanting to show off their latest and greatest for carbide grades for titanium. I’d highly recommend grabbing all the freebies they’re willing to hand out to test out whether they actually make a difference.

Aluminum is about one-third of steel’s density, making it a relatively light metal. Aluminum exhibits remarkably high strength even though has low weight. Hence, this high strength-to-weight ratio makes aluminum ideal for CNC machining automotive and aerospace applications.

The 3xxx series of aluminum has manganese as its principal alloying element. However, you can harden these aluminum alloys to achieve desirable hardness levels since these grades of aluminum cannot be heat-treated. For instance, the aluminum 3004 contains magnesium, and it is among the commonly used aluminum alloys in making beverage cans. Similarly, the 3003 is a general-purpose alloy with vast applications.

Silicon is the major alloying element of the 4000 series of aluminum. The silicon content results in a low melting point of 4xxx aluminum grades. Aluminum 4047 is perfect for sheet and cladding in construction, while aluminum 4043 is ideal as filler rod material for welding 6000 series alloys.

The excellent machinability of aluminum alloys helps mitigate deformation risks during machining. Hence, it ensures higher accuracy in machining custom aluminum parts since CNC machines can easily achieve tight tolerances.

CNC milling is an automated process that often fabricates aluminum parts by rotating a multi-point cutting tool along its axis while the workpiece remains fixed along its axis. The CNC router gradually removes material from the aluminum workpiece at a controlled pace, which can occur along multiple axes. You can achieve high tolerances when milling aluminum.

I really like using rebar for making all kinds of industrial-looking welding projects. It's also useful for things like reinforcing concrete, surprisingly. There are also a lot of different tools...

Aluminum alloys in this category exhibit lower corrosion resistance. Nevertheless, aluminum 2024 comprises manganese and magnesium, making it corrosion-resistant. Hence, it is a commonly used material in aerospace CNC machining.

CNC drilling is a common technique used in creating holes in aluminum workpieces. It involves using a multi-point rotating cutting tool of a specific size to move in a straight line perpendicular to the material that needs drilling. This process is suitable for machining products that require assembly or accommodate screws and bolts.

Lots of tooling manufacturers will showcase their own studies on how much they’ve been able to improve tool life and efficiency with the latest and greatest. To be honest, it’s kind of hard to separate what’s just marketing from what’s legit.

Pro Tip: Using a finishing tool with a small nose radius (like around .008″) might mean a longer finishing cycle, but the lighter cutting pressure and lower heat could mean less warping on precision finishing cuts.

However, the abrasive nature of aluminum may result in more frequent tool changes, which may increase tooling costs. Conversely, steel is more ductile and requires more time and effort to machine, thereby increasing operating costs. In addition, machining steel typically increases tool wear and energy consumption. Despite these challenges, the longevity and durability of steel may be necessary in some applications.
