A Quick Guide to Selecting CNC Machining Materials

2022-09-14 17:17:25

CNC machining is a broad term for a range of machining applications involving the production of various components using a CNC-controlled machine. "CNC" stands for Computer Numerical Controlled machines, which allow the machine to execute numerous functions with minimum human control. With a number of motors and drive mechanisms, the CNC controller moves and controls the machine axes while carrying out the pre-programmed motions.

CNC machining is used in a wide range of industries, including aerospace, medical, oil & gas, hydraulics, automotive, and weapons for a variety of applications. Metal, plastics, glass, composites, and wood are just a few of the materials that can be CNC machined to create finished components and parts. So, If you want to use CNC machining services to manufacture some machine parts and tools, you won't be dissatisfied with the results if you use the right material.

CNC materials have evolved to fulfill the needs of consumers, engineers, contractors, and other industries in order to offer solutions for particular applications. Having a range of materials to pick from is a luxury, but it can also be confusing if you don't first examine your needs and assess your application requirements.

Choosing the right material for CNC machining is the difference between the success and failure of your industrial applications. Asking the following questions helps you narrow down the list of available materials for your specific application:

How will you use the part?

A number of items can be made using similar materials and have different capabilities. Also, not every material withstands all kinds of industrial settings and environments. This is why it is critical to consider the working condition and environment where the parts will be used when choosing CNC machining materials. So, consider the outcomes of your product when you begin your material search.

Where the parts will be used indoors or outdoors?

The indoor and outdoor habitats are significantly dissimilar; one is often far more controlled while the other is fully dependent on the weather. For instance, you must account for moisture in outdoor settings when choosing materials for CNC machining. To preserve a component's integrity over time, your material must be able to withstand the impacts of corrosion, such as rusting.

What is the operating temperature?

As part of the manufacturing process, take into account the operating temperature the component will need to tolerate after it is installed. Make sure the material you select has a melting point lower than the operating temperature. Additionally, be sure the material can withstand any changes in operating temperature.

When CNC machining materials, it's equally crucial to understand the operating temperature so that you can ensure that the heat that occurs from the cutting and shaping of the component won't cause it to deform.

What Is the Stress Load of the Material?

Certain materials may get strained or even break under high-stress loads. Make sure you've taken the material's stress load into account when choosing the right material for your part. Your part's material must be able to resist loads and prevent deformation if it will be subjected to excessive stress.

What are your overall project costs?

Light-weight, high-strength materials are typically the most expensive ones. Selecting a component that satisfies your strength profile, temperature constraints, and fitting requirements is the best strategy for choosing a cost-effective component. It will be simpler to concentrate on those important components if your materials are subject to more stringent criteria or limitations. Getting quotes for different materials to make your component can help you decide what fits your budget while meeting all your requirements.

Although a CNC machine can work with a range of materials, metals, foams, plastics, and wood are the most commonly utilized materials.
