The Journey of Precision Products: Design, Machining, and Delivery

5 minutes, 12 seconds Read

Take a minute to look around you. It is more than likely that you are looking at or even using a precision product right now. Many vital automobile parts, smartphone components, and medical devices are all examples of precision products made from metals, plastics, and other materials. 

CNC machining, or Custom Numerical Control machining, is a form of industrial manufacturing and the current gold standard for modern precision products. A unique code for each product is generated before production which directs the machine to move tools, spin drills, and perform other actions. This computer-automated process allows manufacturers to not only save on production time and reduce waste, but also ensure products are made to precise design specifications and standards that are simply not possible without such technology. 

The impacts that precision products have on our lives are immeasurable. While we may take them for granted, the journey of precision products from design to delivery is the lifework of many skilled professionals. Understanding the process that goes into manufacturing precision products is beneficial for optimizing product development and production for your own projects.

The Benefits of CNC for Precision Product Manufacturing 

One of the biggest benefits of CNC manufacturing is its precision. Even the steadiest human hand is no match for the poise of a machine. CNC machining eliminates the risk of human error, physical or otherwise, in the precision product manufacturing process. 

CNC machines are also exceptionally efficient. They can often complete manufacturing tasks in a fraction of the time that it would otherwise take. This means a faster turnaround, which is especially important in industries such as the medical and defense fields. 

Another benefit is the variety of materials available for CNC manufacturing. Common precision product materials like metals, plastics, and various phenolic materials are all compatible with CNC machinery. The more available materials, the more possibilities for innovation and advancement. 

The CNC Machining Process

Producing a precision product, whether it be an automotive brake caliper, wind turbine blade, surgical scissors, or any other of the endless manufacturing possibilities offered by CNC machinery, all begins with an idea. Here is how that idea for a precision product comes to life through CNC machining.

Product Design

The first step in the precision product manufacturing process is the design. This involves the creation of a 2D or 3D model by using Computer-aided Design (CAD) software. Many companies have in-house design teams responsible for creating design models. High-speed digital design services are also available for a wide range of industries. 

Industry experts believe that up to 70% of product costs are accrued during early-stage design. Design for Manufacturing, or DFM, is a strategy used by many precision product manufacturers to help ensure maximum accuracy for the production phase. Taking the necessary pre-production steps during design is essential for the success of any manufacturing project. This is especially relevant for projects involving CNC machinery, where precision is the name of the game.

Preparing for Production

Once a product has a CAD file made, the next step is to convert that design into a CNC-compatible format. This is essential, as CNC machines are unable to interpret CAD coding. Various software programs are available to bridge the gap between the CAD file and the operating language of CNC machines, known as G-code. 

A precision product is made when a CNC machine uses a unique G-code to direct the movements of its tools. The G-code is essentially a roadmap for the manufacturing process from the machine’s perspective. An experienced machinist will be able to help you be sure your product’s G-code is accurately dialed in before production. 

Precision Product Production

Final production is the next step in the process. Depending on the specifications of the precision product being manufactured, CNC machines can operate by either milling or turning. The exact machine type and production method used are determined by the production material being used and the specific details of each individual product. As the G-code is read, linear transducers and more specialized equipment such as motion potentiometers allow the machine to move along its axis and take the actions necessary to carve out the product. 

The CNC manufacturing process is completed 100% by computer. However, CNC machines are operated by highly-trained workers who are responsible for carefully inspecting products and maintaining machinery when necessary. Once a product has completed the manufacturing process and inspection, it is ready to be delivered to the customer. 

This process for some products can be completed in just a few minutes. Larger products may take a few hours or more. The relatively quick turnaround offered by CNC machines makes them the optimal choice for so many precision product projects. 

Putting Your Precision Product to the Test

Alpha testing can only get you so far. Once your precision product has been manufactured, it is time to put it to the test with real-world applications. This beta testing phase is essential for the successful launch of a precision product. 

Extensive testing, while having costs associated with the process, can end up saving time and money in the long run. The last thing you want is to invest your time and money during the manufacturing process only to learn that the finished product is not suitable for your needs. Working with a manufacturer that offers sample product runs or one that does not require a volume minimum can be very beneficial during this process.

Explore the Endless Potential of Precision Products 

Milling, turning, and other production methods that are at the foundation of the precision products manufacturing industry are not new concepts. The rise of technology and computers has just revolutionized the process and created a whole new world of manufacturing potential. If you can dream it, you can create it with CNC manufacturing. 

Be it aerospace, medical technology, electronics, agriculture, or carpentry, precision products are everywhere. Advances in CNC manufacturing are what have allowed these industries to grow and maintain the highest performance standards in regard to their equipment and tools.
