The Ins and Outs of CNC Machining and What You Need to Know

CNC machining specialists can produce a variety of metal goods and parts by using a complex and detailed process. Understanding the ins and outs of this process will make it easier for you to decide if it is right for your needs or if you need a different option for your facility, so keep reading to learn more.

CNC Machining Definition

Computer Numerical Control (CNC) is a subtractive manufacturing process that uses computer controls and programs to create various tools and parts carefully. The earliest CNC machines in the 1940s and 1950s used punch tape, but modern machines utilize more complex and detailed programs to produce extensive products that meet various safety and stability guidelines.

The CNC Machining Process

CNC machining specialists utilize multiple steps to produce parts. They start by using CAD (computer-aided drafting) programs to create a design. When finished, this design is converted into a CNC program that is fed into the machine. These designs use both 2D vectors or a 3D solid part design to create the completed part. The machine then crafts the part with G-code and M-code (two common programming languages) dictating the tooling actions and how the part is cut and created for your needs.

Common Types of CNC Machining

CNC machining comes in multiple types. The first is CNC drilling. This process uses multi-point drill bits to create holes throughout the piece. The bit feeds perpendicularly to the surface, creating vertical holes throughout the machine. Other elements include counterboring, countersinking, tapping, and reaming. These steps help to create holes of various sizes and shapes.

CNC milling uses rotating multi-point tools to remove material from the piece carefully. The part is fed to the mill in the same direction as the cut, creating shallow and flat surfaces or deep cavities. CNC turning uses a single-point tool to remove material from a part. Think of this process as if you’re working a lathe, as it operates on the same basic principle.

By understanding these steps, you can identify CNC machining specialists who you can trust to handle your needs. Talk with these experts about which machining option works the best for your business. They’ll examine your part needs, talk with you about the various processes available, and create a plan that makes the most sense for your needs. In this way, you can avoid unnecessary costs and expenses. Learn more by contacting Dexter Design today.

How Precision Manufacturing With CNC Mills Can Give You a Competitive Edge

If you’re in the market for true precision manufacturing, CNC Mills can give you an edge over your competitors. With ISO9001:2015/AS9100D CERTIFIED manufacturing, CNC mills provide consistent, high-quality pieces suited to a variety of needs.

But before we get ahead of ourselves, we have to answer a basic question.

What is a CNC Machine?

CNC (Computer Numerical Control) machines are used to create a surface from a piece of stock. This piece is cut to exact specifications so that component pieces with different tolerances can be produced. More precise than manual machining, CNC Mills can cut in 3 dimensions which makes them an excellent tool for precision manufacturing.

Why Are CNC Mills Used?

The accuracy of CNC Machining Advancements ensures a consistently high-quality product. This increased production speed and efficiency is a huge plus when it comes to existing in a competitive market. Since CNC Mills have the ability to cut in 3 dimensions, they are an impressive competitive choice and have the ability to replicate a needed part as many times as necessary with little to no variation.

The tight tolerances and high degree of complexity CNC machines are capable of make them a favorite of precision machinists in all levels of the industry. Tailored for high productivity and optimum performance, these machines can work tirelessly to transform raw materials into the needed sizes and shapes with no errors in production.

CNC mills operate by using rotating multipoint cutting tools and computer controls to shave away bits of metal, wood, glass, plastic, and other materials to create a custom-designed piece or part. This versatile and high-precision way of machining has become a favorite of the industry and adopting CNC mills or CNC milled parts into your workflow can really give your projects a competitive edge in the marketplace.

When Should CNC Manufacturing Be Used?

Precision CNC manufacturing is suitable for a wide variety of materials including metal, glass, plastic, and wood. This kind of versatility makes it a great choice for any business looking for precision-made, error-free parts. Pieces and parts can be made and remade to the same standard for as long as necessary. The result of this is a more reliable final product and a consistency of product across multiple lines or locations.

The bottom line is that precision manufacturing with CNC mills turns out a high-quality and consistent part, which in turn makes for a more consistent and reliable final product.

5 Design Mistakes to Avoid When CNC Machining

CNC machining is a versatile, state-of-the-art manufacturing process for prototypes and end-use products. The technology for computer numerical control or CNC dates back to the 1940s, when the first numerical control (NC) emerged. The early machinery utilized a punching tape that was common in telecommunications. These systems were replaced by analog computing technologies before automated systems set in.

The perspective of rapid prototyping has changed over the years, with CAD designers attempting to keep up with the changes within CNC machining and other prototyping technologies. As such, CNC machining design errors are common. Here are five design mistakes that you should avoid when working with a local machine shop:

1. Overcomplicating the Design

Unnecessary design features can complicate your CNC machining process. Not all features produced from a CAD template may be ideal for the CNC machine process. As a designer, you may need to aim for the fewest cutting and milling requirements to minimize the overall cost of producing your product. The introduction of small pockets and unnecessary aesthetic features can complicate the precision manufacturing process requiring multiple setups by the CNC machining specialists.

2. Requesting Detailed Texts

The CNC mills at our native-owned machine shop are perfectly capable of engraving text, logos, or symbols onto your prototype product. The result of the precision manufacturing process can be eye-pleasing. However, the process may take longer, wasting colossal amounts of time and funds. Detailed engravings or raised texts can significantly spike your prototyping budget. You can utilize alternative processes such as laser marking to work out your aesthetic detailing.

3. Failing to Factor in The Width to Height Ratio

Most product designers wish to have the lightest product in the market, often coming up with thin prototype designs. Your workpiece properties are key aspects that may affect the outcome of the process alongside CNC machining expertise. Extremely thin walls may snap off or distort the machining process. The increased vibration and lowered stiffness may also impact the accuracy at the thin-walled section. Maintaining appropriate wall height to thickness ratio as well as wall height to length ratio can help stabilize your workpiece under the CNC mills.

4. Switching Up Prototyping Processes

Prototyping technologies are rapidly evolving, availing product designers with a range of options to actualize their designs. Most research and design teams often incorporate multiple technologies from their early prototyping to end-product manufacturing. However, most designers often fail to adequately plan for the transitions through the different design stages. This results in challenges of trying to tweak the CNC mills to match the early product design made through a 3D printer.

5. Incorporating Deep Cavities

A full-service CNC machine shop may have different mills with various head drill bits. The cutting edges are of finite length, limiting the depths to which accurate cavities can be achieved. Deeper cavities may have our minority-owned machine shop creating adjustments to accommodate the pockets of space required to avoid damaging the product edges. This may result in an expensive prototyping and end-product manufacturing process.

CNC machining boasts of precision manufacturing that appeals to most research and design teams. However, design errors by your CAD team can result in a mismatch with the CNC machine settings that can create a setback for your product development.
