How CNC Prototype Machining is Used in Different Industries?

In all the industries where precision machining is demanded, CNC prototype machining can be used. A functional prototype is mostly used in these industries to check how well the original product performs. Due to these functional prototypes, prototype CNC machining is mostly a top priority because it offers a pre-judging on the part’s strength, mechanical stability, or other characteristics. But these facilities are not offered by other prototyping methods and therefore, a compelling option for the following crucial industries.

Aerospace Industry

The aerospace industry is one of the most crucial industries where the tiniest error may lead to unimaginable devastating damage to aircraft or human lives. So, there is no room for any error in this industry and requires an extremely higher degree of precision. Therefore, this industry uses CNC prototype machining for pre-judging and testing of different aircraft parts.

Prototyping assists in testing the functionality of different parts before fitting into an expensive aircraft. CNC machining is widely used in the aerospace industry for making different aircraft parts such as engines, avionics, sensors, airframe, connectors, etc.  If you want to know more about this industry, click here to see the Importance of CNC Machining in the Aerospace Industry.

Defense Industry

The defense industry is probably the most crucial in the world as it is responsible for the country’s sovereignty and guarantees its citizens their freedom. In the defense industry, war aircraft and ammunitions require design confirmation and testing before going into the field. So, a trusted method is utilized for prototyping, and CNC machining prototypes fulfill this need tremendously. Different high-precision plane parts, transportation components, communication components, ammunition, etc. are produced using CNC machining.

Medical Industry

As medical science is evolving rapidly and with this revolution, medicine is also evolving expeditiously. This evolution in medicine requires a highly rising demand for new medical equipment. Therefore, medical companies need satisfaction regarding the new products that can cure the disease for which it is manufactured. So, they require a prototype that can make sure everything will be perfect as desired. Because it involves the risk of human lives and the company’s reputation too. Here, CNC prototype machining is responsible for making medical equipment. Orthotic devices, safe enclosures, implants, MRI machines, research equipment, etc. are made using CNC machining.

Automotive Industry

Well, CNC prototype machining is playing a great role here in the automotive industry too. As automobile corporate giants keep on developing and changing their automotive designs continuously. But they are pretty much concerned about their every new design because ordering a mass production before testing it can cause them a substantial amount of money if not worked properly. Their market repute can also get hurt.

CNC prototype machining is responsible for developing automotive prototypes as per exact specifications. CNC prototype machining is also used in manufacturing other transportation parts like shipping vessels, transport trucks, and many more.

Advantages of Prototype CNC Machining

1.Cost-Efficient

If you are required quality prototypes quickly at a reasonable price then CNC machining prototype services are the most feasible option for you. Your specified prototype manufacturing will start after designing CAD, generating CAM code and finally, the machine will be set up to perform machining operation. It is not like other prototyping methods where you are required few days to get your samples like the injection molding method. CNC machining prototype services are cost-efficient.

  • High-Precision  

CNC prototype machining offers a high precision part manufacturing that is becoming very crucial and demanding for numerous industries. A three-dimensional computer-aided design is created that tells what the finished part or component will look and function like. Then a code is generated accordingly in terms of prototype specifications and feed to the machine. This is all the process that makes CNC machining high precision.

  • From Prototype to Production

While manufacturing the prototype, all the work has already been completed. It just requires the customer’s satisfaction who wants to test the functionality of the part or use the prototype to pitch the product to a potential investor. Once this all is done then it only requires a few more days to manufacture the whole order and consignment will be ready to ship depending on the quantity only.

  • Material Friendly

Another benefit of CNC prototype machining for specimen manufacturing over other methods is that the manufacturer can use a variety of materials as demanded by the customer. In any case, if you need a prototype made of plastic or metal, do not worry it can be accommodated in CNC machining.




    Disadvantages of Prototype CNC Machining

    1. Expensive than 3D Printing

    Greater human supervision, large power supply consumption, and expensive raw materials make CNC prototype machining more expensive as compared to 3D printing. Whereas, 3D printing requires less human supervision and electricity consumption. The raw materials that 3D printout use is much cheaper than the expensive ones used in CNC machining. As this method is expensive, therefore, many engineers are forced to go for other prototyping processes. Although it offers great benefits for some fresh and small startups it may be quite expensive.

    • Some Geometrical Restrictions

    Despite offering a large degree of geometrical flexibility by 4-axis and 5-axis machining centers but still these machines have some limitations. For a prototype with some complex internal geometric specifications, CNC prototype machining is not suitable as it is restricted by cutting tool angles. In this case, additive manufacturing processes will be a better choice.

    Remember 3D printed prototypes are no exception and they also have their limitations. But a 3D digital design that is manufactured using a 3D printer may be impossible to fabricate using any of the production equipment like machining centers, injection molding equipment, etc. Geometrical flexibility for prototypes is only helpful if that flexibility can be replicated on the final part.

    • Waste Material

    As CNC machining is a subtractive process and by applying drilling, lathing, grinding, milling, and routing, a large percentage of the raw material is removed. As this removed part cannot be utilized again so it has to be scrapped. Due to the increased material usage and wastage, the CNC prototype machining process becomes hazardous for the environment. As the scrapped parts are mostly recycled making this method environmentally unfriendly.

    Conclusion

    Prototyping is very suitable to test your part before investing in mass production. There are many methods for prototype manufacturing but CNC prototype machining offers a great package with high precision production, faster manufacturing, material friendly characteristics, prototype leads to production without wasting time, and many more.
