Ce este prototipul rapid al pieselor cnc : (Ghidul de prelucrare CNC 2020?)

Ce este prototipul rapid al pieselor cnc?
Un prototipul rapid al pieselor cnc  este primul pas pentru validarea capacității unui produs. Este cel mai direct și mai eficient mod de a identifica defectele, imperfecțiunile și defectele produselor de proiectare și, astfel, de a îmbunătăți în mod intenționat defectele până când acestea pot găsi un defect în produse.

Rapid prototyping is a specialized technique for producing high quality physical models. The prototype is very useful for improving product design as it can be used for full production or engineering testing. The goal of rapid prototyping is fast and cost effective without investing in metal molds.

Nowadays rapid prototyping is booming in the industry and it is not for less, it saves thousands of bucks in design failures or testing of final parts and is not as expensive as companies think.

CNC rapid prototype

With the help of prototipul rapid al pieselor cnc, computer-aided numerical control, machine tools in a company are electronically controlled. This is an enormous relief for the industry, as fewer human resources have to be relied on. Similarly, errors are minimized and time is saved.

CNC production is related to rapid prototyping as follows: If larger models are required as a prototype, CNC machines are used for this, as these are equipped with the advantages mentioned. At the end you get a CNC rapid prototype. This is extremely important for the later series production, as readjustments are still possible.

The advantages of the cnc parts rapid prototype

More and more companies that want to produce in large numbers are turning to 3D printing. The positive aspects of this are obvious:

• The process is extremely quick and saves an enormous amount of time.
• Using the finished prototipul rapid al pieselor cnc, you can later see exactly where possible defects exist. These are eradicated before a whole range of these products hit the market.
• The models, which were produced by CNC milling with the aid of the 3D printer, are particularly impressive. It is due to their very good surface and their ability to implement even very filigree pieces with a perfect fit.

In addition to the CNC rapid prototype, there are other, different areas of application for rapid prototyping:

• The so-called Rapid Tooling helps companies to implement tool pieces quickly
• With rapid manufacturing, components are created using an informal manufacturing process, directly from the CAD data.

Frezarea CNC este unul dintre procesele de prototipare rapidă în care datele CAD sunt convertite complet automat în piese prelucrate din materiale originale. Modelele produse pe mașinile de frezat portal sunt potrivite ca pre-serie pentru producția ulterioară de serie de turnare prin injecție și ca modele de demonstrație și expoziție originale.

Prototipare rapidă cu CNC

Serviciul de  prototipul rapid al pieselor cnc is one of rapid prototyping technologies that take years to exist. It is a traditional technology that consists of removing material from an initial block of the part material (usually metal) to obtain the desired shape.

Parts can be machined in weeks and that is why we have included it in this list. But it is not as flexible a technology or with the urgent delivery times. These are usually obtained with 3D printing or laser cutting.

CNC is sometimes the only option when you want metal parts (metal 3D printing is costly for most parts). But it has the downside that it is usually more expensive than 3D printing unless Try long production runs.

Cnc parts rapid prototype allows you to scale the volumes of a product from one to a hundred thousand without investing in equipment. It’s cheap, has a fast turnaround time. Moreover, it offers many different materials you can work with. Furthermore, it is accurate enough for repeatable production.

There are many ways to optimize and improve a design to get better results at the lowest cost. Here are five things you should definitely consider for your next CNC project.

Cnc parts rapid prototype Specify only critical tolerances as needed

Where possible, specify only critical tolerances when absolutely necessary for your design. For example, when specifying a radius on a 2D or 3D drawing, it is best to do so on functions that perform a critical function for that part.

By limiting the number of critical dimensions, it allows the CNC machinist more freedom in creating the part. And avoids costly setups and measurements for non-critical areas.

Don’t go too small in cnc parts rapid prototype

Follow the standard on inside corners

Another good design tip to keep in mind when prototipul rapid al pieselor cnc has a standard radius of 3mm or greater for internal corners. Because milling small internal radii is time-consuming, expensive and requires special settings.

A ball nose end mill is often used when milling 3D shapes and radii. As with the swivel inserts, these rounded profiles create corner radii in their size and shape. It is impractical to make a smaller radius because the milling is done at right angles to a vertical face.

Therefore, it is difficult to mill small radii on internal corners without the use of very small cutters. And if you do, the CNC mill will run much slower.

Know your surface area before you go for cnc rapid prototyping

It is important to keep in mind that a small, precise cutter must be introduced into the workpiece at a significantly slower speed to avoid destroying the workpiece. Machining a certain surface area requires the cutter to perform multiple passes. Each time removing small amounts of material which can increase delivery times.

Conclusion

If you have decided to use CNC machining to make prototipul rapid al pieselor cnc or die casting tool, many of these same design rules may apply. It is best to keep the corner radii large, not only to facilitate tool production, but also to improve the quality of the resulting molded part.

Likewise, keeping critical dimensions to a minimum will speed up tool making and be more forgiving of the expansion and contraction that occurs when these tools are heated and cooled during manufacturing.
