Designers can incorporate different CNC machining materials depending on their application. It is crucial for business owners to write down all the specifications of their end-products before starting the production process.
Although CNC machining can involve a variety of materials in production, designers should pitch the best material that will promote product efficacy, thus customer satisfaction.
Some of the most crucial factors manufacturers should consider in the production process include durability and suitability. Business owners should make all product information accessible by manufacturers to improve production outcomes.
Qualities of an Ideal CNC Machining Material
You can implement a few guidelines in your CNC machining processes, specifically CNC mold material choice that is crucial for product structure and function. For example:
Water contributes to corrosion. You should consider the material’s resistance to water, especially if your part will have exposure to moisture—for example, metals rust when in water.
Therefore, considering the resistance of a material to fresh and salty water is crucial in the design process. It would help if you also thought about a material’s ability to absorb moisture. Certain plastics can take in water leading to part failure.
Strength is a crucial component to consider. Product engineers need to consider all aspects regarding material strength. Although various elements make up the strength of a material, comprehensively analyzing all features ensures optimal product efficacy. The most crucial ways product engineers evaluate strength include:
Before settling on a material, determine its reaction in pulling force. Tensile strength means a material’s ability to resist pull force. The amount of tensile strength you need will depend on the function you want your part to perform.
Some materials adopt a new shape, especially upon loading weight. Product engineers should consider the material’s ability to adapt to the original form after stretching upon load removal.
Compression or load-bearing:
A constant force can be overwhelming, especially if the material lacks enough compressive or load-bearing ability. Choose a strong material to withstand continuous weight if required for your application.
Tearing is a possibility in operation. The inky way to prevent this fate from occurring and thus hindering a part’s performance is to select a material that is resistant to tearing.
Product designers should consult online material data that contains crucial technical information like material strength and thus determine if a certain material is ideal for the specific function you desire due to its tolerance limits.
Heat is another crucial factor to consider when selecting a material for your part. Product designers should detect any cooling and heating cycles that the resulting part will experience as it functions and thus settles on a thermally stable material.
The effects of heat on certain materials can be destructive. For example, thermal degradation occurs when certain plastics operate in hot environments, thus leading to critical part failure. The straightforward way to select an ideal material is to compare its melting point and expected working conditions and determine thermal stability to support functioning.
4. Corrosion resistance
Although most people determine corrosion resistance by considering a material’s interaction with water, this is not the only cause of corrosion. Corrosion may be an adverse chemical reaction that occurs on your part upon exposure to foreign substances like acids.
There are relevant material data sheets all over the internet to help you predict expected outcomes upon exposing your metal or plastic to different chemical substances.
Product designers usually require materials that machine quickly, especially during the production process. This factor mainly affects metals and carbon fiber more than plastics.
If material is extremely tough, it might take longer for cuttings tools to shape the material into the perfect tool. Engineers should consider the efficacy required in longer production lines and choose easily malleable materials but strong enough to support product function.
Consider your machine and what materials it would best handle, fast and efficiently, without damage.
Product designers are finding ways to maneuver out of paying high production costs. However, opting for cheaper materials is not the best way to save on cists because cheap may mean low quality and thus less predictability on product function.
It would be best to conduct thorough research on materials and providers to find them a trusted place to purchase your materials. You should always put outcomes ahead and consider the factors mentioned above before looking at the material cost.
Quality materials may not come cheap. However, affordable options can provide the efficacy you desire, especially during part performance.
The above factors are the main things to consider when selecting a material for the CNC machining process of producing parts. Consult a trusted CNC machining provider to understand your material options and how they can promote durability, flexibility, and improved performance during functioning.
