First of all, the design and development of processing technology

Before CNC machining, the first need for product design and development of processing technology. According to the requirements and functions of the product, the designer uses CAD (computer aided design) software to design the product. Then, the process engineer formulates the processing technology according to the shape, material and processing requirements of the product, including selecting suitable cutting tools, cutting parameters, cutting paths, etc.

Secondly, the preparation of processing procedures

The machining program is the core of CNC machining, which contains the action instructions of the machine tool, cutting parameters, cutting path and other information. The preparation of the processing program requires the use of CAM (computer-aided manufacturing) software, the product design file into a processing program. When writing the processing program, it is necessary to consider the cutting performance of the material, the rationality of the process and other factors to ensure the efficiency and quality of the processing process.

Then, machine clamping and tool clamping are carried out.

Before CNC machining, it is necessary to clamp the workpiece on the machine tool and select the appropriate tool for cutting. Machine clamping is the process of fixing the workpiece on the machine tool. It needs to consider the shape, size and processing requirements of the workpiece. Tool clamping is the process of installing the tool on the machine tool. It is necessary to select the appropriate tool type and specification, as well as the correct installation method. The accuracy and stability of machine tool clamping and tool clamping have an important impact on machining accuracy and efficiency, so it needs to be carefully adjusted and checked.

Next, a machining operation is performed

After the machine clamping and tool clamping are completed, the CNC machining operation can be started. The operator inputs the written processing program into the CNC machine tool controller, and then through the instructions of the controller, the machine tool performs cutting according to the path and speed specified by the program. During the processing, the operator needs to monitor the processing status and adjust the cutting parameters and tools in time to ensure the processing quality and efficiency.

Finally, the processing inspection and finishing

After CNC machining is completed, the workpiece needs to be inspected and trimmed. The inspection can be carried out by measuring tools and equipment to detect the size, shape and surface roughness to verify whether the workpiece meets the requirements. Dressing is the process of dressing, grinding or polishing the processed parts to eliminate possible processing defects and improve the accuracy and surface quality of the processed parts.

In summary, the CNC machining process covers the design and development of machining processes, the preparation of machining procedures, machine tool clamping and tool clamping, machining operations, and machining inspection and finishing. Each link requires accurate operation and strict control to ensure the efficiency of the processing process and the quality of the processed parts.

The development of CNC machining provides high-precision and high-efficiency parts manufacturing solutions for various industries. Compared with traditional manual operation and conventional machining, CNC machining has the following advantages:

1, high precision

CNC machining can achieve high-precision parts processing through the precise control of CNC machine tools and the high-speed rotation of tools. The machining accuracy can reach sub-millimeter or even higher level to meet the requirements of complex parts.

(2) High efficiency

CNC machining adopts computer programming and automatic control, which can realize automatic continuous processing and greatly improve production efficiency. The time and workload of manual operation are reduced, and the production efficiency and production capacity are improved.

3-Flexibility

CNC machining can be flexible according to different product needs and design requirements. Only by modifying the processing program and adjusting the tool, the processing of different parts can be realized, thus avoiding the trouble of replacing equipment in traditional machining.

4. Repeatability

CNC machining can achieve precise cutting paths and processing parameters by writing processing programs and automatic control, ensuring the consistency and repeatability of processing. It is not affected by the technical level and experience of the operator, and reduces the influence of human factors on the processing quality.

5. Versatility

CNC machining can achieve a variety of machining operations, such as milling, turning, drilling, tapping, etc. A CNC machine tool can complete a variety of processing tasks, reducing equipment investment and floor space.

In summary, CNC machining provides high efficiency, high precision, flexibility, repeatability and versatility of parts manufacturing solutions. It is widely used in various industries, such as aerospace, automotive, electronics, medical equipment, mold manufacturing, etc.

In the field of aerospace, CNC machining can manufacture complex shapes of aviation parts, such as turbine blades, engine parts, aerospace structural parts, etc. Due to the high precision and repeatability of CNC machining, the quality and performance requirements of parts can be ensured.

In the automotive industry, CNC machining can manufacture automotive engine parts, chassis parts, body parts, etc. Through CNC machining, high precision and consistency of parts can be achieved, and the performance and safety of the car can be improved.

In the field of electronics, CNC machining can manufacture electronic parts, circuit boards, housings, etc. Due to the high efficiency and flexibility of CNC machining, it can meet the rapid development and production needs of electronic products.

In the field of medical equipment, CNC machining can manufacture medical equipment parts, artificial joints, dental equipment, etc. The high precision and repeatability of CNC machining can ensure the quality and safety of medical equipment.

In the field of mold manufacturing, CNC machining can manufacture various types of molds, such as injection molds, die-casting molds, stamping molds, etc. Due to the versatility of CNC machining, high-precision machining of complex molds can be achieved.

In general, the development of CNC machining provides high-efficiency, high-precision and flexible parts manufacturing solutions for various industries. It can be controlled by computer program machine tools for automated processing, greatly improving production efficiency and product quality.

One of the advantages of CNC machining is high precision. Due to the use of computer program control, very precise processing can be achieved to achieve micron-level accuracy requirements. This is very important for some parts that need precision fit, such as gears, threads, etc.

Second, CNC machining has a high degree of flexibility. By changing different tools and adjusting the machining path, various complex shapes of parts can be manufactured. Moreover, the production of different products can be realized only by modifying the program, without redesigning and manufacturing new tooling.

CNC machining is also repeatable. Once the correct machining procedures and parameters are set, the machine can continue to operate and maintain consistent machining quality without manual intervention. This is very important for mass production to ensure that each part meets the specified size and quality requirements.

In addition, CNC machining has versatility. By selecting different tools and processing methods, various processing operations such as drilling, milling, cutting, and turning can be realized to meet the processing needs of different parts. This makes CNC machining a versatile manufacturing process.

Overall, CNC machining is an efficient, precise, flexible and reliable part manufacturing solution. With the continuous development of technology, CNC machining will play an increasingly important role in various industries to promote the progress and development of the manufacturing industry.
