What is Rapid CNC Machining?
Rapid CNC machining is a subtractive process in which a computer directs different machines to make many products. CNC means computer numerical control machining, and it is very popular in rapid prototyping and custom production. Many people use the manufacturing process because of its accuracy, precision, and automation..
What is the rapid prototyping?
1. Inspect the appearance design, reflect the designer's creativity in the form of physical objects, and facilitate the discovery of deficiencies and defects in the design during the process of developing the appearance of new products.
2. Check the structure and function design, intuitively reflect whether the structure is reasonable or not, and the difficulty of installation, which is easy to find the engineering and process problems existing in the product structure, and optimize the product structure and function.
3. Reduce the risk of direct mold opening, avoid losses, and save development costs.
4. Before the mold is developed, the prototype model is used for early publicity (such as participating in exhibitions) and preparation for production, which is pioneering.
Car Prototype by CNC
Usually, the products that have just been developed or designed need to be prototyped. Prototype is the first step to verify the feasibility of the product. It is a direct and effective way to find out the defects, deficiencies and drawbacks of the designed products, so as to improve the defects in a targeted manner. , until the deficiencies cannot be found from individual prototypes. According to the effect to be achieved, it can be divided into appearance prototype, structural prototype, functional prototype and so on.
The processing technology of the prototype mainly includes: CNC processing and molding, 3D printing SLA/SLS molding, vacuum small batch molding, etc.
Rapid CNC Machining is the main equipment for the production of prototypes. The processing method is to excavate and carve various types of metal materials such as aluminum, copper, stainless steel, and plastic into the physical samples we need.
Why You Should Use CNC Machining for Prototypes
The general notion about CNC machining is that it is used in large scale manufacturing. However, CNC machining use goes way beyond that. This is evident in its use in making prototypes. To understand why you should use CNC machining for prototypes, you must know its pros and cons. Below are the pros and cons of CNC machining for prototypes.
Pros of CNC Machining for Prototypes
There are many prototyping processes in the manufacturing world. However, Rapid CNC Machining is one of the best. This is due to the many advantages it provides. Below are a few advantages you get to gain by using the process.

Precision and Tolerance
After stating the size and shape in your CAD file, you will want to use a manufacturing process to give you the desired result. To obtain the desired outcome, you will need to use a high precision value machine. Although the dimensions may not be the same as that of the model, the true value deviation will be extremely small. This implies that Rapid CNC Machining has a better tolerance level when compared to other means of prototyping.
When manufacturing using CNC machining, you will obtain multiple results whose dimensions will be the same as one another. The is because CNC machining is a software-controlled manufacturing process. Thus, once you have programmed the software’s dimensions, you can manufacture as many similar products as possible.
Minimize Humans’ Involvement
CNC machining reduces humans’ involvement in the manufacturing process. This significantly reduces the chance of errors due to operators. It further minimizes the mistakes that can occur during the manufacturing processes. So, when you need to develop a model, the CNC machine can continue to operate for a long time.
It takes not much time to finish the manufacturing process after using the CNC machining prototype service. This saves time, and it is highly essential when making prototypes. CNC machining is also ideal for prototypes because it allows the mass making of products with high quality. Therefore, it is easy to tweak part of the design, make a prototype, and check the required properties. All this is doable in a short time.
It Supports Many Materials
Compared to other methods, CNC prototype machining is an ideal way to develop prototypes because of the many materials it supports.
Tips for Designing CAD for Prototype CNC Machining
Before manufacturing a product, the producers used to design illustrations of what they want the product to look like before introducing it into the market. Below are the tips you need when designing CAD files for prototype CNC machining to obtain the desired products precisely, faster, and at a lesser cost.

Use a Reliable CAD Software for Your Design
When choosing a CAD software to use, there are many things you must look at. The two crucial things are the ease of use and technical know-how. Therefore, you will easily specify the shape, volume, and size of the prototype. The most commonly used and renowned CAD software are AutoCAD, CATIA, SolidWorks, and Civil 3D.
Have a Checklist for Your Design
Before you start designing, you need to have a checklist that will contain what you want to appear on your prototype. Having a list will minimize the errors you can commit when designing.
Do not Complicate Your Drawing
Ensure you represent the features of the material you are designing with easily understandable things such as figures, symbols, and pictures. Complicating your drawing can make designing difficult to understand.
Check for the Quality of Your Design
After you have finished designing, ensure you crosscheck your design with the features you have stated in your checklist to see if there is any omission or addition. You can then make the necessary adjustments before finalizing your design.
