For small businesses and startups, traditional machining techniques can be expensive and time-consuming. However, CNC prototyping machining offers businesses or manufacturing companies that want to produce parts a fast, cost-effective way to maintain accuracy and quality.
One of the main reasons why CNC prototyping is the first choice for prototyping is its flexibility. Through this prototyping method, manufacturers can design, develop and modify products in a short period of time.
What is CNC Prototype Machining?
CNC prototype processing, that is, computer digitally controlled precision machining, is one of the new processing technologies. It mainly uses CNC numerical control machine tools to process raw materials to produce samples that meet the requirements. This processing method has the characteristics of high speed and good surface quality of the sample. After completing the surface spraying, silk screen and electroplating processes, the CNC processed products are very similar in appearance to the molded products.
Why choose CNC technology for prototyping? What are the advantages and disadvantages?
The advantages of CNC prototype machining include the following main aspects
High precision
CNC technology accurately controls the movement trajectory and cutting parameters of the tool through a computer, which can achieve very high machining accuracy and ensure that the size and shape of the prototype are consistent with the design requirements.
high efficiency
CNC machine tools can automatically complete most processing tasks, reduce manual operations, and greatly improve production efficiency. At the same time, by optimizing cutting parameters and processing paths, processing time can be further shortened.
Material adaptability
CNC technology can be adapted to the processing of a variety of materials, including metals, plastics, composite materials, etc., providing more material choices for prototype production.
High flexibility
CNC machine tools can adapt to the processing needs of prototype parts of different shapes and sizes by changing tools and fixtures, and have high flexibility.
CNC technology also has some disadvantages in prototyping
Equipment costs are higher
CNC machine tools are more expensive and may be unaffordable for some small businesses or startups.
The technical threshold is high
CNC technology requires professional operating skills and programming knowledge, and operators need professional training to be competent.
The processing process is complex
For some particularly complex or special-shaped prototype parts, CNC processing may require the design of complex fixtures and tools, making processing more difficult.
Not suitable for small batches or rapid iterations:
Although CNC machining has advantages in accuracy and efficiency, it may not be as cost- and time-effective as other rapid prototyping technologies for prototyping that requires frequent design changes or low-volume production.
The guidelines for the CNC rapid prototyping process are as follows:
Design preparation
First of all, CAD (computer-aided design) data is required as the basis for processing. This data should contain information such as detailed dimensions, shape and materials of the required prototype parts.
Programming and Setup
Programming of CNC machine tools based on CAD data. The programming process includes determining cutting path, cutting depth, cutting speed and other parameters. At the same time, it is also necessary to set up the working coordinate system of the machine tool to ensure positioning accuracy during the processing.
Material preparation
According to the design requirements, prepare the required raw materials. CNC technology can process a variety of materials, such as metals, plastics, etc., so it is necessary to select suitable materials for processing.
Installation and fixing
The material is placed on the CNC machine’s table and secured using clamps or other fixtures. Make sure the material does not move or deform during processing.
Start processing
Start the CNC machine tool and start processing according to the preset program. The machine tool’s cutting tools will cut according to the programmed path, gradually processing the raw material into the required prototype.
Monitor and adjust
During the machining process, it is necessary to closely monitor the operating status of the machine tool to ensure that the machining process proceeds smoothly. If any problems or deviations are found, the machine tool parameters should be adjusted in time or the machine should be shut down for inspection.
Post-processing
After processing is completed, the prototype parts undergo necessary post-processing. This may include steps such as sanding, polishing, and painting to improve the appearance and performance of the prototype.
Inspection and delivery
Finally, the prototype is quality inspected to ensure it meets the design requirements. If qualified, it will be delivered to the customer for subsequent use or testing.
Please note that the specific steps of the CNC rapid prototyping process may vary depending on factors such as machine tool model, material type, and design requirements. Therefore, in actual operation, it needs to be adjusted and optimized according to specific conditions. At the same time, in order to ensure processing quality and safety, operators need to have relevant professional skills and experience.
involved in the process
The crafts involved in the CNC Prototype Machining mainly include the following key steps
CNC turning
In this process, the workpiece is firmly sandwiched on a rotor or a shaft. When the workpiece is rotated, the cutting tool is installed in a fixture on the mobile slider to achieve accurate production of concentric circular shape on the periphery of the workpiece.
CNC milling
Different from the turning, the workpiece in the milling process is kept static, and the cutting tool rotates on the main axis. The workpiece is usually placed in the machine horizontally and moved along the X and Y movement. Milling and driving are the two most common processes in the operation of CNC machine tools.
CNC grinding
This process is mainly used to make very flat surface on metal components. During the grinding process, the workpiece was installed on the workbench and moved back and forth horizontally on the sliding platform under the wheel. In addition, there are special types of grinding such as round grinding and optical grinding, which are used to handle workpieces of different shapes and materials.
In the process of processing prototypes throughout CNC, you also need to pay attention to some key process elements. First of all, according to product needs and design drawings, use CAD software for three -dimensional modeling of parts to provide accurate data foundations for subsequent processing.
Import the designed three -dimensional model into the CAM software to plan and simulate the processing process to ensure the efficiency and accuracy of the processing process. The processing program generated by CAM software is then transmitted to the CNC machine to perform actual processing operations. Finally, quality detection and post -processing of the processing parts complete to ensure that it meets the design requirements.
The crafts involved in CNC processing prototype are a complex and fine process, and the operator needs rich experience and skills. Through accurate design, programming and processing operations, high -quality, high -precision prototypes can be produced, which provides strong support for subsequent product development and production.
Applications of CNC Prototype Machining
CNC processing prototypes play a vital role in product development, design verification, functional testing and small batch production, so it is used in these industries.
Concept verification
In the early days of product design, designers can use CNC to process physical models quickly to verify basic elements such as design concepts, ergonomics, and spatial layout to intuitively present the actual effects of the design plan.
function test
The prototype processed by CNC can be directly used for functional testing, such as the strength test of the mechanical structure, the combination of accuracy test, and the dynamic performance test of the motion component to help engineers discover and improve design defects in design defects
Design modification and optimization
In the process of product design iteration, the CNC processing prototype can allow the design team to quickly obtain physical samples, perform feel, appearance and assembly test, which is convenient to quickly adjust the design details and shorten the product development cycle.
Marketing display
Through the high -precision prototype of CNC processing, enterprises can carry out marketing and pre -sale activities before the product listing, display the actual appearance and texture of the products to potential customers, collect market feedback, guide the improvement of the final product
Small batch production
For small -scale or customized products, CNC processing can flexibly and quickly produce a small amount of components, without the need for traditional large -scale mold investment, which reduces the cost threshold of small batches of production.
Quick prototype manufacturing
In addition to adding material manufacturing (such as 3D printing), CNC reduction manufacturing is also an important means of fast prototype manufacturing. It is especially suitable for precision prototypes for making metal materials and meets high requirements for hardness, heat resistance, and abrasion resistance. Application scenario.
