The process of CNC machining parts is a high-precision and high-efficiency machining method, which uses the CNC system to control the action of the moving parts through the servo drive system to realize the processing of the parts. The following is a detailed introduction to the CNC machining parts process:
First, process characteristics
High precision: CNC machining can achieve high precision parts processing and meet the precision machining needs of complex parts.
High efficiency: Through automated machining and optimized machining paths, CNC machining can significantly improve production efficiency.
High flexibility: The CNC machining system can flexibly adapt to the processing needs of different parts and achieve multi-variety and small-batch production.
Second, process steps
1. Part drawing analysis:
Process analysis of parts drawings to determine the processing content and technical requirements. This includes the feature analysis of the surface of the part, the geometric condition analysis of the outline of the part, the analysis of the processing content and its technical requirements.
2. Process design:
According to the processing requirements of parts, design specific processing procedures. This includes the division of the work step, the positioning of the workpiece and the selection of the fixture, the selection of the tool and the determination of the cutting amount.
3. Programming:
According to process design, write NC machining program. The programming needs to consider the moving path of the tool, cutting parameters, etc., to ensure the smooth progress of the machining process.
4. Program verification and modification:
Verify the written program to ensure the correctness and feasibility of the program. If problems are found, modify and improve them in time.
5. Machine tool and workpiece preparation:
Start the machine and manually return to the reference point to establish the machine coordinate system. At the same time, according to the processing requirements of the parts, select the appropriate fixture and complete the workpiece clamping and alignment.
6. Tool preparation:
Select the appropriate tool according to the processing requirements, and complete the installation and tool matching. Set the tool parameters correctly in the numerical control system.
7. Processing process:
Under the control of numerical control system, the machine tool is processed according to the predetermined program. During the processing process, it is necessary to pay close attention to the running state and processing quality of the machine tool to ensure the smooth progress of the processing process.
8. First inspection:
After machining, the first part is inspected. The inspection contents include dimensional accuracy, surface roughness, etc., to ensure that the processing quality meets the requirements.
9. Mass production:
If the first piece passes the inspection, mass production can be carried out. In the mass production process, it is necessary to check the processing quality regularly to ensure the stability and reliability of the production process.
Third, precautions
Tool Management:
Check the wear of the tool regularly, and replace the tool with serious wear in time. Reasonable arrangement of tool storage and use sequence to avoid cross contamination.
Operation skills:
Operators need to master the correct operation methods and processing skills to better play the processing performance of CNC lathes. At the same time, it is necessary to constantly learn and master new processing technologies and methods to improve processing efficiency and quality.
Optimization of processing parameters:
According to the machining requirements of the parts and the performance characteristics of the machine tool, the machining parameters such as cutting amount and feed speed are reasonably selected. By optimizing the processing parameters, the processing efficiency and quality can be improved, and the processing cost can be reduced.
Fourth, application field
The process of CNC machining parts is widely used in machinery manufacturing, automobile, aerospace and other fields. With the continuous development and progress of the manufacturing industry, CNC machining technology will continue to innovate and improve, providing strong support for the development of the manufacturing industry.
In summary, the process of CNC machining parts is a high-precision and high-efficiency machining method. It involves multiple steps and links, and requires the cooperation of programmers, operators and quality inspection personnel to ensure the smooth progress of the processing process and the high standard of processing quality.
