CNC Machining Copper: Benefits, Drawbacks, and Properties Explained

CNC Machining Copper: Benefits, Drawbacks, and Properties Explained

Have you recently come up with a product design that features metals or metal alloys? If so, you’re likely looking for an ideal manufacturing technology to fabricate your parts accurately and precisely while meeting the required tolerance requirements.

CNC machines are among the most in-demand manufacturing technologies for metals today primarily because of their high accuracy, precision, and compatibility with a broad range of metals and metal alloys.

However, when it comes to CNC machining copper, there are several things you must keep at the back of your mind. First, you need to understand that pure copper in itself is challenging to manufacture due to its high ductility and high cold workability. Second, a ton of copper-based alloys now exist that offer similar (or even better) properties than pure copper and are relatively easy to fabricate using CNC machines.

You will have no problem choosing an ideal copper alloy for your design requirements as long as you understand the properties, benefits, and drawbacks of each of these alloys.

This article presents five common copper alloys, including their properties, benefits, drawbacks, and applications. But before we delve right into it, let’s take a look at two things you must consider when CNC machining pure copper.

Copper CNC Machining: 2 Things to Consider

Copper CNC Machining

No. 1 Choose the Right Machining Tool Material

Because pure copper is very soft, it typically causes high tool wear and poor chip formation during machining. With copper CNC machining, there is also the possibility of formation of built-up edge—which happens when part of the copper workpiece breaks away and is pressure welded to the cutting tool, causing poor surface finish of the machined copper parts.

We would advise you to use cutting tools made of high-speed steel (HSS) to machine copper as they are generally known to mitigate these challenges. Also, you must sharpen your cutting tools to a good cutting edge before CNC machining copper.

No. 2 Specify the Right Feed Rate

Feed rate describes the rate at which the CNC cutting tool is fed (or advanced) against the workpiece. We recommend low to moderate feed rates for CNC machining copper since high feed rates are generally known to cause high temperatures, making copper much more difficult to machine with precision.

But if your product demands that you use high feed rates, then be sure to use cutting fluids (or coolants) to get rid of the heat.

CNC Machining Brass: What are the Best Alloys, and What Else Should You Know?

CNC Machining Brass: What are the Best Alloys, and What Else Should You Know?

Are you looking for a material with good mechanical properties, strong corrosion resistance, good malleability, high conductivity, and even good acoustic characteristics? If so, you should consider brass because this remarkable metal has all those properties in one.

Brass is an alloy of copper and zinc, the proportions of which can be varied to achieve different properties for the overall alloy. For that reason, brass is widely used in various industries and for applications ranging from musical and electrical to germicidal and antimicrobial.

This article will not only introduce you to the pros and cons of brass as a CNC machining material, but it will also help you to determine the best brass grades for use in your next project.

Brass in CNC Machining: Advantages and Drawbacks

machining brass

As we mentioned before, brass provides advantageous properties that make it an ideal option for a variety of applications. Why is that? When it comes to CNC machining, there are a few fundamental properties that make this material phenomenal.

The first one is the overall machinability. In simple terms, this property refers to how easy it is for the material to be machined. Brass is one of the easiest materials to machine. While many consider free machining steels the comparison baseline for machinability, brass alloys generally have better machinability.

The strength and hardness properties of brass are also useful for a wide range of applications. Although brass has good strength, it is relatively soft compared to other materials such as steel alloys and titanium and is generally weaker than them.

However, this contributes in part to its much better machinability over those materials. So for applications that do not require the very high strength and hardness of steels or titanium, brass can be a worthwhile materials selection.

Brass alloys exhibit the same favorable strength and hardness characteristics you would expect from various aluminum alloys. They also boast remarkable corrosion resistance, especially when alloyed with small amounts of aluminum.

While they do see use in some electronics — thanks to good overall conductivity — one of the significant considerations for brass over aluminum tends to be how visually appealing brass is without the need for additional coatings.

Best Brass Grades for CNC Machining

Brass, in its simplest form, is a combination of copper and zinc. However, alloying brass with combinations of other metals such as tin, aluminum, lead, and iron can produce brass alloys with unique characteristics.

Even in small proportions (<0.05%), the addition of those elements can also result in enhanced properties. For instance, a small amount of tin provides a brass alloy with exceptional resistance to seawater corrosion.

Aluminum for CNC Machining: Know the Benefits, Drawbacks, and Alloys

Aluminum for CNC Machining: Know the Benefits, Drawbacks, and Alloys

What makes CNC machines so unique and widely used in a broad range of industries?

Product designers looking to turn their product idea into reality often ask this question. And the answer goes beyond the high accuracy and precision that CNC machines offer.

Without a doubt, accuracy and precision are essential criteria when choosing any machining technology. But what sets CNC machines apart from other machining technologies is their compatibility with a broad range of engineering materials, including aluminum.

But just because CNC machines simplify aluminum machining, it doesn’t mean fabricating aluminum parts is any less complex than it used to be. There are many aluminum grades (or alloys) available in the market today, and the success of your project will depend on you choosing the most suitable aluminum alloy for your project.

This article presents seven aluminum grades commonly available in the market today, including their properties, advantages, and suitability for different design requirements. It will serve as a guide to help you make the right choice for your project.

Some Benefits and Drawbacks of Aluminum for CNC Machining

cnc machining aluminum

Here are some of the benefits of aluminum for CNC machining.

  1. Good Machinability: Aluminum is easier to machine than many other metals. It chips easily, making it easy for CNC machine operators to create complex parts quickly and accurately.
  2. High corrosion resistance: Aluminum develops a thin hard film of oxide (aluminum oxide) when exposed to air or other oxidizing agents. This oxide makes aluminum corrosion-resistant and prevents chemical damage.
  3. High strength-to-weight ratio: Given its high strength, aluminum is remarkably light. As such, you can make aluminum parts thicker and stronger while still reducing weight in applications that require lightweight materials.
  4. Recyclability: Aluminum has high recyclability, making it perfect for businesses looking to mitigate the material wastage challenge of CNC machining.
  5. Custom Finishing: Aluminum offers a wide range of surface finishing options, including anodizing and painting, to give your parts the perfect custom look (Related Post: Why Choose an Anodized Finish for Aluminum?)

Like with many other engineering materials, aluminum has its drawbacks. Here are the disadvantages of aluminum for CNC machining:

  1. Machining Difficulty: Aluminum can be difficult to machine due to its relatively low melting temperature, and its oxide coating can sometimes damage tooling.
  2. Cost: The energy costs involved in machining aluminum parts are somewhat high, making them more expensive.

What Type of Steel is Best for Your CNC Machined Part?

What Type of Steel is Best for Your CNC Machined Part?

As you may have realized, CNC machining is an exceptionally versatile way to manufacture your steel part. However, you may be wondering what type of steel is the best option for your project and how you can tell if you are choosing the correct one.

This article will explain the properties you must consider for your steel machined part and our top 10 types of steel for CNC machining to give you some excellent options for your next project. This way, you can be sure to get the best results.

The Benefits of Steel and its Challenges for CNC Machining

Benefits of Steel and its Challenges for CNC Machining

While the CNC machining process can produce high-quality and precise parts from many materials, those materials with poor machinability often produce unsatisfactory results. When it comes to the wide variety of steel alloys available on the market, you’ll find a large number of steel alloys with good machinability. In fact, the AISI machinability rating is generally determined relative to B1112 alloy steel.

As we’ve explained previously, to determine a material’s machinability, you should, at a minimum, consider the material’s hardness, allowable heat inputs, and the desired surface finish to assess if it is a suitable material for CNC machining.

Hardness is a key indicator of machinability, and if the material is too hard or too soft, it can cause delays, extra labor time, or even require special equipment. Many of the steels you would consider for your projects are not free machining steels. So they will typically exhibit a higher hardness than free machining steel and feature a machinability rating below 100%.

While hardness generally directly correlates with machinability, the impacts of heat input can be more challenging to determine. Some materials behave differently at high temperatures, and some can even melt. The high heat inputs from machining can affect the microstructure of some materials more than others. For instance, Grade 17-4 stainless steel may need to be solution heat treated after machining to maintain certain desirable properties.

Finally, while higher hardnesses and different sensitivities to heat effects impact the machinability of steel alloys, they can exhibit excellent surface finishes. While this does depend on the grade, materials that exhibit a suitable machinability index generally also exhibit a good surface finish, which can often be further enhanced by a polishing treatment, either chemical or physical.

What is CNC Machining? Understand This Fascinating Manufacturing Process

What is CNC Machining? Understand This Fascinating Manufacturing Process

Take a look around, identifying and naming all the products in your surroundings, including phones, tablets, laptops, wrist watches, vehicles, and desks. Most, if not all of these items, are end products of CNC machining.

CNC machining is a manufacturing process that uses computerized instructions (or a computer program) to accurately and precisely create the parts you need.

The computerized nature—coupled with the high accuracy, precision, and broad range of material compatibility—of CNC machining make it one of the most in-demand manufacturing processes today. For example, Tech Giant Apple had to ditch conventional machining and rely on this technology to manufacture the unibody outer shell of the MacBook.

Do you want to learn about how CNC machines work, the machining process, and the different types of machines available today? You’re in the right place!

What is CNC, and How Do CNC Machines Work?

CNC stands for Computer Numerical Control; this is simply a method for automating the control of machine tools.

Computer numerical control machines rely on computer instructions and a CAM (computer-aided manufacturing) program to control, automate and monitor machine tools’ movement to create the desired part.

Look at it this way. A CNC machine takes a stock piece of material (for example, an aluminum block) and transforms it into a finished product through controlled material removal processes.

Let’s break the CNC machining process down even further.

The CNC Machining Process Explained

We can break the machining process down into four distinct steps:

#1 Create Your 2D and 3D Designs

2D and 3D Designs

The first step of the CNC machining process is to create the 2D and 3D drawings of your part using computer-aided design (CAD) or computer-aided manufacturing (CAM) software like SolidWorks and Autodesk Inventor. When creating your 2D and 3D drawings, you must specify all important dimensions, features with tolerances, and surfaces with specific surface finishing requirements.

The goal is to make an accurate representation of the part (or product) you’re looking to create.

#2 Generate the Toolpath

A toolpath is a series of coordinate locations (or the path through space) that a CNC cutting tool will follow during the machining process to produce the desired geometry of the workpiece.

To help better understand “toolpath” in CNC machining, let’s consider the image below where we have a block whose features reside on the XY plane. To create the desired part (a block with two cuboid cavities), you must first position your cutting tool to make cuts along the Z-axis before moving along the XY plane.

A CNC machined block with simple features

CAM software typically has functionalities that allow you to define your machining strategy, including the types of cutting tools to use, feed rates, and cutting tool speed, among others. Once you’ve generated the toolpath and defined your machining strategy, proceed to the next step of the process.

#3 Convert your Machining Parameters into CNC-compatible File

The final step you need to take on the CAM software is to convert your machining strategy into what is called the G-code. A G-code is a computer language that a CNC machine can understand and execute; it tells the machine precisely what steps to execute to make your part.

After generating the G-code, export it to the CNC machine.

#4 Execute the Machining Operation

This is the phase where you insert the workpiece into the CNC machine and install all the cutting tools required for the machining operation. Once these steps have been completed, initiate the machining program and watch the machine create the part you need autonomously.

Types of CNC Machines

CNC machines come in several types, with each type having its functions and machining capability.

CNC Machines

CNC milling machines (or CNC mills) allow you to produce flat, helical, and contoured surfaces of various configurations. In contrast, CNC lathes are better suited for machining cylindrical shapes; they allow you to perform turning operations, including taper turning, drilling, knurling, grooving, and parting operations.

CNC plasma cutters, laser cutting machines, and electric discharge machines (EDM) have similar functions and machining capabilities. However, they differ in their modes of operations and their cutting mechanism. For more information, take a look at our article about the different types of CNC machines.
