CNC machining, also known as numerical control machining, refers to the processing carried out using numerical control machining tools. Because CNC machining is programmed and then controlled by a computer, it has the advantages of stable processing quality, high processing accuracy, high repeatability accuracy, the ability to process complex surfaces, and high processing efficiency. So, how does the Shenzhen CNC machining center divide the processing procedures?
I. How to divide processing procedures?
The division of numerical control machining processes can generally be carried out in the following ways:
The tool centralized sequencing method is to divide the process according to the tools used, and use the same tool to process all the parts that can be completed on the part. Use the second and third knives to complete the other parts that they can finish. This can reduce the number of tool changes, compress the idle travel time, and minimize unnecessary positioning errors.
2. For parts with a large number of processing contents, the processing parts can be divided into several sections according to their structural characteristics, such as inner shape, outer shape, curved surface or plane, etc. Generally, planes and positioning surfaces are processed first, followed by holes. Process the simple geometric shapes first, and then the complex ones. Process the parts with lower precision first, and then the parts with higher precision requirements.
3. For parts prone to processing deformation, due to the possible deformation after rough machining, shape correction is required. Therefore, generally speaking, for those that need to undergo rough and finish machining, the processes should be separated. In conclusion, when dividing processes, it is essential to flexibly consider the structure and processability of the parts, the functions of the machine tool, the amount of CNC processing content of the parts, the number of installations, and the production organization status of the unit. It is also suggested that whether to adopt the principle of process concentration or process dispersion should be determined based on the actual situation, but it must be as reasonable as possible.
