Create CNC process function and CNC part processing process plan:

(1) CNC process considers the process of processing parts, clamping and positioning of processing parts, tool selection, process route that can be simplified in conventional process, cutting method and process parameters, etc.

(2) Kunshan CNC machining process design is mainly used to guide CNC programming.  Our company combines the responsibilities of CNC technicians and programmers, and the programmers are responsible for the CNC machining process of the whole mold, which improves the work efficiency.

(3) CNC processing has a high degree of automation and many influencing factors.  Quality safety is very important in CNC processing and must be guaranteed.





(4) The preparation of cnc processing technology should have strict strip steel rationality.  CNC process is complex and has many influencing factors.  It is necessary to think deeply about the whole process of CNC processing.  Only with good strip steel rationality can CNC process be well programmed.  Due to the high degree of automation and poor adaptability of CNC processing, when problems occur, it is difficult for the staff to correct them on site.  The light people make processing defects, and safety accidents occur on the way.  Therefore, the CNC process must be designed systematically in advance.

(5) Good inheritance of CNC technology.  It has been proved to be a good CNC process in production, which can be used to make templates, save them as files, and call them when processing similar parts in the future to save time and ensure quality.

For CNC machining process plan, it will be regarded as the state space of a series of programs from the initial state of the part (male and female mold core blank) to the state (part).  The CNC sequence sorting must comply with the following general rules:

1. First primary parameter and then secondary parameter.

2. Face before hole, milling before drilling.

3. Coarse before refined.

4. First process the inner cavity, then process the contour.

5. According to the sequence of processes, the tool diameter varies from large to small.

6. The processing of the previous process will not affect the clamping and positioning of the next process.

7. Put the same tooling and fixtures together to reduce repeated clips and positions.

8. CNC process must be centralized.

9. Do not use program instructions that weaken part stiffness first.

Good CNC machining process planning needs to consider the following aspects:

Whether the technical requirements of the parts can be met, whether the efficiency of CNC processing can be improved, the processing cost is low, and the quality control is good.

Therefore, the overall CNC machining process plan is generally as follows:

1. Selection of CNC machine tools.

2. Select the processing method.

3. Determine how to clamp the part, and then select clamp.

4. Positioning method.

5. Inspection requirements and methods.

6. Select the tool.

7. Error control and tolerance control in processing.

8. Define CNC process.

9. CNC sequence.

10. Select cutting parameters.

11. Prepare NC machining program table.
