Aluminum is one of the most popular material choices for CNC machining projects because of its desirable physical properties. Not only is it strong and durable, making it ideal for making mechanical parts, but its oxidized outer layer resists corrosion from the elements. These advantages make aluminum parts common in all industries, even in the automotive, aerospace, healthcare, and consumer electronics sectors.

Aluminum also has some special advantages that can simplify and improve the CNC machining process. Unlike many other metals with similar material properties, aluminum has excellent machinability, and many grades of aluminum can be effectively penetrated by cutting tools, easily chipped, and relatively easy to form. Because of this, aluminum can be machined more than three times faster than iron or steel.

This article describes some of the main benefits of aluminum CNC machining and why it is one of our most widely requested prototyping and production processes. It also proposes alternatives to aluminum machining, as other metals and plastics offer similar benefits to aluminum in addition to their own unique advantages.

1.Benefits of Aluminum CNC Machining

1) Machinability

One of the main reasons engineers choose aluminum for machining parts is that the material is easy to machine. While this may seem more beneficial to the machinist who makes the part, it also has significant benefits for the business that orders the part and the end user who ultimately uses it.

Because aluminum breaks easily and is easy to shape. It can be cut quickly and accurately using CNC machines. This has some important consequences:

1. The short time of the machining operation makes the machining process cheaper because the machinist requires less labor and the machine itself requires less operating time;
2. Secondly, good machinability means less deformation of the part as the cutting tool passes through the workpiece. This allows the machine to meet tighter tolerances as low as ±0.025 mm, achieving higher accuracy and repeatability.

2) Corrosion resistance

Different grades of aluminum vary greatly in their corrosion resistance, that is, how well they can resist oxidation and chemical damage. Fortunately, some of the most popular CNC machining grades of aluminum have the strongest corrosion resistance. For example, has excellent corrosion resistance, as do other alloys lower in the strength range. Strong aluminum alloys may have poor corrosion resistance due to the presence of alloying copper.

3) Strength-to-weight ratio

Aluminum has desirable physical properties that make it ideal for machinery and parts. Two of the most important of these properties are high strength and light weight, both of which make the material ideal for critical components required by the aerospace and automotive industries. Aircraft fittings and automotive axles are two examples of materials that can be successfully machined with aluminum.

However, different grades of aluminum have different uses. General-purpose grades such as are used in a variety of parts due to their good strength-to-weight ratio, while high-strength grades such as may be more suitable for aerospace and marine applications.

4) Electrical conductivity

CNC machined aluminum parts are used in electrical components due to their electrical conductivity. While pure aluminum is not as conductive as copper, it has a conductivity of about 37.7 million Siemens/meter at room temperature. Alloys may have lower conductivity, but aluminum materials are significantly more conductive than materials such as stainless steel.

5) Anodizing potential

Machinery aluminum parts are particularly popular in the consumer electronics industry, not only for their strength and weight requirements, but also for their aesthetics. In addition to being easily painted and dyed, aluminum can also be anodized, a surface treatment process that thickens the protective oxide outer layer of a part.

The anodizing process is usually performed after machining is completed and involves passing an electric current through the part in an electrolytic acid tank, resulting in an aluminum piece that is more resistant to physical impact and corrosion. Importantly, anodizing makes it easier to add color to machined aluminum parts because the anodized outer layer is highly porous. The dye can pass through the porous parts of the outer layer, and because the dye is embedded in the hard exterior of the metal part, it is less likely to chip or flake off.

6) Recyclability

High recyclability makes aluminum a top choice for businesses that want to minimize their environmental impact or those that simply want to reduce material waste and recoup some of their expenses. Recyclable materials are particularly important in CNC machining, where cutting tools generate relatively high amounts of waste.

2.Alternatives to aluminum in CNC machining

Businesses may seek alternatives to aluminum for CNC machining for a variety of reasons. After all, aluminum has some drawbacks: its oxide coating can damage tools, and it's generally more expensive than alternatives like steel, in part because of the high energy costs of aluminum production. Here are some potential machining alternatives to aluminum, highlighting their differences and similarities to the popular silver-gray metal.

1) Metals

'Steel and stainless steel

Better than aluminum:

1. Strength
2. Temperature resistance

Worse than aluminum:

1. Machinability
2. Weight

Steel and stainless steel are widely used materials in CNC machining. Due to its high strength, steel tends to be better suited for high-stress applications and those that require strong welds. Steel can withstand extremely high temperatures, and stainless steel can be heat treated to enhance its corrosion resistance.

However, despite the careful engineering of machining steel to improve machinability, aluminum remains the more machinable of the two materials. Steel is also heavier and harder than aluminum, which may or may not be ideal depending on the application. If high-temperature resistance is the main consideration and weight is not, then steel may be a good alternative to aluminum.

'Titanium

Better than aluminum: Strength-to-weight ratio

Worse than aluminum: Cost

Titanium can be used as a like-for-like substitute for aluminum because its main advantage is its excellent strength-to-weight ratio'one of aluminum's main advantages. Titanium weighs similarly to aluminum but is nearly twice as strong. Like aluminum, titanium also has strong corrosion resistance.

These advantages are reflected in the higher price of titanium alloys. While titanium alloys are an excellent choice for manufacturing parts such as aircraft components and medical devices, their cost can be too high. When lightweighting is the main consideration and there is some flexibility in the manufacturing budget, machining titanium is a suitable substitute for aluminum.

'Magnesium

Better than aluminum:

1. Machinability
2. Weight

Worse than aluminum:

1. Machinability
2. Corrosion resistance

Although not the most commonly machined material, the lightweight metal magnesium has many of the advantages of ordinary aluminum alloys. In fact, magnesium is one of the easiest metals to machine today, making the machining process fast and efficient. What is a potential disadvantage for machine shops? Magnesium chips are highly flammable, and water further exacerbates their hazards, which means that machinists must be careful when removing debris.

' Brass

Better than aluminum: Some aesthetic applications

Worse than aluminum: Cost

Brass is a golden-looking metal that is highly machinable and slightly more expensive than aluminum. Brass is often used to make components such as valves and nozzles, as well as structural components, and is highly machinable and suitable for large-volume orders.

' Copper

Better than aluminum: Electrical conductivity

Worse than aluminum: Machinability

Copper shares a variety of material properties with aluminum. However, copper's excellent electrical conductivity makes it an ideal material for a variety of electrical applications. While pure copper is difficult to machine, many copper alloys have machinability similar to commonly used aluminum grades.

2) Engineering Thermoplastics

' POM (Polyoxymethylene)

Better than aluminum:

1. Electrical insulation
2. Low friction

Worse than aluminum:

1. Strength
2. Heat resistance

CNC machining projects don't have to be limited to metals. In fact, depending on the application, a variety of engineering thermoplastics can match or even surpass some of the advantages of aluminum. Since aluminum is favored for its excellent machinability, a viable plastic alternative is POM (Delrin), which, like aluminum, is very suitable for processing.

POM has a low melting point, but as a plastic, its strength is very high. At the same time, as an electrical insulator, POM is very suitable for manufacturing parts such as electronic housings, and is also suitable for manufacturing mechanical parts. However, given that its insulating properties are very different from aluminum, it should only be used as a like-for-like substitute in situations where thermal and electrical conductivity are not important.

'PTFE (Teflon)

Better than aluminum:

1. Electrical insulation
2. Very low friction

Worse than aluminum: Strength

Like POM, PTFE (Teflon) is a highly machinable thermoplastic and an excellent electrical insulator. However, unlike POM, PTFE is also resistant to high temperatures (up to 260°C), making it a viable aluminum substitute in high-temperature applications. In addition, its high chemical resistance makes PTFE (Teflon) a popular processing material for food industry parts.

' Peep

Better than aluminum: Medical uses

Worse than aluminum:

1. Processability
2. Cost

Although PEEK is more difficult to process than the first two thermoplastics, its high strength and thermal stability up to 260°C make it a real alternative to aluminum. Therefore, PEEK is popular for processing parts such as valves, bearings, pumps and nozzles, proving its metal-like performance.

But the main problem is the price. As a high-performance polymer, PEEK is one of the more expensive processable thermoplastics, so it is only suitable for processing projects where common materials such as aluminum cannot be used.

' Anti-lock brake system

Better than aluminum: Thermal shock resistance

Worse than aluminum: Strength

ABS is commonly used as an injection molding material and has also been used as 3D printing filament in recent years. Although ABS has little in common with aluminum, it is still a versatile and lightweight CNC processing material with above-average impact strength.

'More

Most of the other machinable plastics are very different from aluminum, including PC, ABS+PC, PP, PS, PMMA (acrylic), PAGF30, PCGF30, DHPE, HDPE, and PPS.

Alternatives to specific aluminum grades

3.Combining CNC machining with other processes

If aluminum remains the material of choice for a project, CNC machining can be combined with other manufacturing processes to create more complex, higher-performance aluminum parts. Doing so maximizes the functionality of aluminum while gaining the benefits of multiple production processes. In addition to being an integrated manufacturing process, CNC machining can also be used to improve or modify parts made using other machinery. Extrusion, casting, and forging processes can all be complemented with machining processes to create better aluminum parts.

1) Aluminum Extrusion + CNC Machining

Extrusion is the process of forcing molten material through holes in a die to produce elongated parts with continuous contours. While aluminum extrusion is an effective way to produce functional parts with high-quality surface finishes and complex cross-sections, it is limited in scope because these cross-sections must remain consistent throughout the part.

Unless, of course, the part is modified after extrusion. Since aluminum extrusions tend to involve forgeable, ductile, and machinable aluminum grades such as and , the extruded parts can then be post-processed'cut in a variety of ways using a CNC machining center. Combining aluminum extrusion and CNC machining is an excellent way to produce resilient parts with complex cross-sections and irregular geometries.

2) Die Casting + CNC Machining

Die casting is a manufacturing process in which molten metal is forced into a die cavity at high pressure. Since the required tool steel molds are expensive to manufacture, it is often used to produce parts in large quantities. Along with steel, magnesium, and zinc, aluminum is one of the most popular metals for pressure die casting, and die-cast aluminum parts often have excellent surface finish and dimensional consistency.

These advantages can be combined with those of CNC machining. By die casting aluminum parts and then using a machining center for further cutting, parts with smooth surfaces and more complex geometries can be produced that would not be possible using either process alone. If reducing costs is more important than ensuring high precision or creating thin walls, gravity die casting can be used instead of pressure die casting.

3) Investment Casting + CNC Machining

Investment casting is a metal casting process that uses wax patterns to make metal parts. Like other casting processes, the process produces parts with excellent surface finish and high dimensional accuracy. The process also has unique advantages: it can be used to make more complex parts than die casting, and the parts have no parting lines. Aluminum alloys are common materials for investment casting, and cast aluminum parts can be post-processed for refinement.

4) Forging + CNC Machining

Many machinable aluminum alloys are also suitable for the ancient forging process, which involves shaping the metal through compressive forces. (This usually requires hitting the metal with a hammer.) For example, aluminum is suitable for hot forging with closed dies ' a common process for producing automotive and industrial parts.

Forged aluminum parts can be post-processed with CNC machining centers. This is advantageous compared to pure machining, because forged parts are generally stronger than fully cast or fully machined parts. However, post-machining allows more complex geometries to be created without completely compromising the integrity of the part.

Benefits of Aluminum that Make it Ideal for CNC Machining

CNC Aluminum Machining Milling

Aluminum alloys offer varying properties that make them ideal for CNC machining applications. This section discusses the benefits of aluminum in CNC machining:

Strength-to-Weight Ratio

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.

Machinability

It is easier to form and machine aluminum alloys than other metals. You can use machine tools to easily and quickly cut aluminum since it is soft and chips easily. Aluminum alloys are less expensive and require minimal power to machine.

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.

Corrosion Resistance

Aluminum exhibits natural corrosion resistance in different atmospheric conditions. However, you can anodize your aluminum machined parts to enhance these properties. Also, it would help to understand different aluminum grades have varying resistance to corrosion. Nevertheless, the most widely used CNC machined grades have excellent corrosion resistance.

Electrical Conductivity

Pure aluminum possesses electrical conductivity of about 37.7 million Siemens per meter at room temperature. Aluminum alloys provide electrical conductivity for their parts, making them applicable for electrical components, even though they may exhibit lower conductivities than pure aluminum. However, aluminum alloys would be unsuitable if electrical conductivity is not a primary requirement of your machined part.

Custom Finishing

Aluminum machined parts are compatible with extensive surface finishes such as chromate conversion coating, anodizing, powder coating, and painting to achieve the preferred custom appearance for your project.

Recyclability

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.

Moreover, this attribute makes aluminum suitable for manufacturers who want to recover expenditure or lower material wastage. Likewise, the recyclability of aluminum makes it a more environmentally friendly metal to machine.

Generally, pure aluminum material contains 99 to 99.6% aluminum elements, with other alloying elements, including zinc, magnesium, silicon, manganese, and copper, making up the remaining percent. This section discusses the common aluminum alloys based on the primary alloying element:

Series

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 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.

Series

The main alloying element of the 2xxx series of aluminum is copper. These are heat-treatable aluminum alloys made almost as hard and strong as steel with precipitation hardening. This heat treatment process increases yield strength in these aluminum alloys by heating the aluminum material to make precipitates of the other metals emerge from the metal.

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

Series

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 contains magnesium, and it is among the commonly used aluminum alloys in making beverage cans. Similarly, the is a general-purpose alloy with vast applications.

Hence, the aluminum is the most popular aluminum alloy in aerospace applications. It also has aerospace-grade strength, which makes it ideal for making complex parts.

Cost of Aluminum CNC Machining

The cost of CNC machining of aluminum consists of the following major aspects.

• Raw material prices
• Machining hours
• labor costs
• tool wear and tear
• product complexity

The cost of aluminum has a definite advantage over CNC machining of other metals such as steel. Aluminum's raw material costs are typically lower than steel, which is reflected in the overall price. Aluminum is softer, making it easier and quicker to machining'typically taking only 1/2 to 1/4 the time required for steel parts. This efficiency cuts labor costs and accelerates production.

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.

Common Aluminum CNC Machining Techniques

Milled Machining Aluminum Part

This section discusses the different machining processes for aluminum alloys.

CNC Milling

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.

CNC Drilling

CNC Milled Aluminum Prototype

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.

CNC Turning

Aluminum CNC turning involves rotating the workpiece while the single-point cutting tool remains stationary along its axis. Either the cutting tool or the workpiece performs the feed motion against the other, depending on the machine to remove the material. The raw material rotates at high speed while the turning center removes material to create the desired shape.

Key Challenges in Aluminum CNC Machining

Manufacturers and product engineers often encounter setbacks in aluminum CNC machining regardless of its remarkable machinability. This section discusses some of these challenges along with possible solutions:

Aluminum's Malleability

Aluminum's high malleability can result in complications like poor surface finish, burrs, and chip formation during aluminum CNC machining. Built-up edges often occur as the material sticks to the cutting tool. Consequently, it results in reduced tool life.

Solution: You must use the right cutting tools specifically designed for machining aluminum, including carbide or polycrystalline diamond (PCD) tools. You can also use cutting fluids to efficiently dissipate heat and reduce friction, ensuring superior surface finishes. You may need to secure the aluminum workpiece to minimize deflection and chatter during machining.

Thermal Issues During Machining

Aluminum alloys dissipate heat faster during CNC machining because of their high thermal conductivity. Consequently, this can lead to workpiece thermal deformation, low machining accuracy, and tool wear.

Solution: Use a high-pressure coolant system in aluminum CNC machining to mitigate overheating. Likewise, you can reduce cutting speed to ensure low heat generation, preventing the thermal expansion of the workpiece.

Wear and Tear of Machining Tools

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.

Solution: It is advisable to use high-quality tools with extraordinary hardness and toughness to mitigate frequent tool changes while increasing productivity. Also, coatings such as TiAlN (Titanium Aluminum Nitride) or TiCN (Titanium Carbo-Nitride) ensure improved tool life in high-temperature operations.

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.
