Write and record the development of technology with deep insight
Super detailed CNC processing process, deserve you to collect
CNC machining (computer numerical control machining) is a method of machining using a computer-controlled numerical control machine tool, which is widely used in the manufacture of parts in various industries. It controls the machine tool to cut along the specified path through the pre-written processing program, so as to realize the processing of the workpiece. The following will introduce the process flow of CNC machining.
First, design and formulate the processing technology
Before CNC processing, it is first necessary to design the product and formulate the processing technology. Designers use CAD (Computer Aided Design) software to design products according to product requirements and functions. Then, the process engineer formulates the processing technology according to the shape, material and processing requirements of the product, including selecting appropriate cutting tools, cutting parameters, cutting paths, etc.
Secondly, write the processing program
The machining program is the core of CNC machining, which includes information such as machine tool action instructions, cutting parameters, and cutting paths. Writing processing programs requires the use of CAM (Computer Aided Manufacturing) software to convert product design files into processing programs. 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 set-up and tool set-up
Before CNC machining, it is necessary to clamp the workpiece on the machine tool and select a suitable tool for cutting. Machine tool clamping is the process of fixing the workpiece on the machine tool, which 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 setup and tool setup have a significant impact on machining accuracy and efficiency, so careful adjustments and inspections are required.
Next, the processing operation
After the machine setup and tool setup are complete, CNC machining operations can begin. The operator inputs the prepared machining program into the controller of the CNC machine tool, and then through the instructions of the controller, the machine tool cuts according to the path and speed specified by the program. During the machining process, the operator needs to monitor the machining status and adjust cutting parameters and tools in time to ensure machining quality and efficiency.
Finally, process inspection and trimming
After the CNC machining is completed, the workpiece needs to be inspected and trimmed. Inspection can be carried out by measuring tools and equipment to detect the size, shape and surface roughness to verify whether the processed parts meet the requirements. Trimming is the process of trimming, grinding or polishing the workpiece to eliminate possible processing defects and improve the precision and surface quality of the workpiece.
In summary, the CNC machining process covers the design and development of machining processes, writing of machining programs, machine tool clamping and tool clamping, machining operations, and machining inspection and trimming. 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 the CNC machine tool and the high-speed rotation of the tool. The machining accuracy can reach sub-millimeter or even higher level, which meets the requirements of complex parts.
2. High efficiency
CNC processing 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 capacity are improved.
3. Flexibility
CNC processing can be processed flexibly according to different product needs and design requirements. It is only necessary to modify the processing program and adjust the tool to realize the processing of different parts, avoiding the trouble of replacing equipment in traditional machining.
4. Repeatability
CNC machining can achieve precise cutting path and machining parameters by writing machining programs and automatic control, ensuring the consistency and repeatability of machining. It is not affected by the operator’s technical level and experience, which reduces the influence of human factors on the processing quality.
5. Versatility
CNC machining can realize a variety of machining operations, such as milling, turning, drilling, tapping and so on. A CNC machine tool can complete a variety of processing tasks, reducing equipment investment and floor space.
To sum up, CNC machining provides parts manufacturing solutions with high efficiency, high precision, flexibility, repeatability and versatility. It is widely used in various industries such as aerospace, automotive, electronics, medical equipment, mold making, etc.
In the field of aerospace, CNC machining can manufacture aerospace parts with complex shapes, 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, the high precision and consistency of the 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, casings, 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 device 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 various industries with high-efficiency, high-precision and flexible parts manufacturing solutions. It can control machine tools through computer programs for automatic processing, which greatly improves 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, reaching micron-level precision requirements. This is very important for some parts that require precise fit, such as gears, threads, etc.
Secondly, CNC machining has high flexibility. By changing different tools and adjusting the processing 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 program and parameters are set, the machine tool can run continuously and maintain consistent machining quality without manual intervention. This is very important for high-volume production to ensure that each part meets the specified size and quality requirements.
In addition, CNC machining offers 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 solution for parts manufacturing. With the continuous development of technology, CNC machining will play an increasingly important role in various industries and promote the progress and development of the manufacturing industry.
