The accuracy and precision of 5-axis milling is second to none. You can cut a workpiece in just a single setup. This feature eliminates the need for manual repositioning and adjusting the surface to be machined. Furthermore, 5-axis milling fabricates parts exactly to specifications which is essential in new product development. These parts have a smooth cut edge and superior finishes that may not need further processing and surface treatment.
- Ease of Customization and Personalization
5-axis milling is perfect for new products that come with customized and personalized details. You can use it to create products tailored to different clients’ needs. It is fast and can cut logos, texts, images, and engravings with ease. This allows you to meet various customers’ requirements and specifications. Hence, you are sure of more sales and stay competitive in the market.
Importance of 5-Axis CNC Milling from Prototype to Production for New Product Development
The journey in new product development can be a bumpy one if you do not employ advanced manufacturing techniques. From prototyping to full production, 5-axis milling allows for the creation of precise and accurate components. Let’s explore how the capabilities of 5-axis CNC are beneficial in the different stages of new product development.
- Prototyping
Prototyping is the first stage when developing a new product. It involves creating a physical representation of the design and bringing it to life. This mock looks like and functions the same way as the intended product. With 5-axis milling, you can check if an idea works and how practicable a new design is.
The final step in prototyping is reviewing the design in detail to catch errors. You do this by presenting the physical product to important stakeholders and getting their feedback. You then iterate quickly using a milling machine till an optimal product is produced.
- Engineering Validation Testing (EVT)
EVT comes right after prototype production and focuses on the engineering and technical aspects. The prototype contains all the essential features needed to work perfectly. The main aim is to test the design and be sure all parts of the prototype function as they should in the real world.
This engineering prototype acts as a demonstrator that helps to identify shortcomings and flaws easily. Note that EVT is not a one-time thing and can take an average of 5 weeks. You continue to make changes till you meet all your product requirements. 5-axis milling provides a means of carrying out this detailed analysis and testing with ease.
- Design Validation Testing (DVT)
In this stage, you validate and finalize the product design. 5-axis milling plays a huge role in DVT as you can seamlessly machine complex geometries for performance evaluation. The stakeholders you focus on here are the customers themselves.
DVT ensures that the product functions not only as intended but also meets customers’ expectations in terms of aesthetics and appearance. It makes sure that the products are safe and reliable and that customers have a good experience using them. When carrying out DVT, you are looking at the entire product rather than individual parts.
- Production Validation Testing (PVT)
This is the third and final validation phase in product development. Here, you are assessing the CNC milling process itself and all the tools you use. 5-axis milling comes with a high speed and does not sacrifice quality which makes it perfect.
What you do in PVT is fine-tuning and modifying production parameters before mass production begins. The goal is to ensure that the machine and tooling can consistently produce high-quality parts on a large scale. PVT can take up to 3 weeks and you may need to produce up to 10% of the first order to make a decision.
- Full Production
After completing the PVT stage, you can start mass-producing and supplying the products to your customers. At this point, you have validated the product and optimized the CNC milling process for large-volume manufacturing. 5-axis milling ensures consistency in every batch and you can produce hundreds and thousands of high-quality parts.
After manufacturing begins, you should give room for continuous improvement. This is because not every flaw may have been detected during product development. Hence, you should continuously analyze data and make changes to improve product quality.
Challenges and Considerations of Using 5-Axis CNC Milling in Product Development
Though 5-axis CNC milling seems like the messiah when moving from prototyping to large-scale manufacturing, there are some challenges you may encounter. The following are some shortcomings of 5-axis milling in product development.
- Cost
The cost of 5-axis CNC milling can be on the high side especially if you are just starting. It may be expensive to purchase the tools and software you need to make accurate products. Furthermore, some projects may need customized jigs and fixtures to guide the cutting tool and secure the workpiece. These high upfront costs can be a barrier for small businesses.
- Programming Complexity
5-axis milling machines are more complex to program when compared to conventional machines. This machine moves along different linear and rotational axes which makes programming tasky. It requires accurate calculations to avoid collision and interference. All these potentially raise costs and overall expenses.
- Operator Skill Level
To use 5-axis CNC milling for new product development, you must have adequate skill and expertise. You should understand the machine’s capabilities, material compatibility, and tooling requirements. Operating a 5-axis CNC milling machine requires experience so you can interpret and troubleshoot the CAM software output.
Conclusion
