when dividing the working procedures for sheet metal processing, it must be controlled according to the structure and manufacturability of the parts, the efficacy of the machine tools in the numerical control machining center, the content of the numerical control machining of the parts, the installation frequency and the production organization of the unit. It is also suggested to adopt the principle of process concentration or the principle of process dispersion, which should be decided according to the actual situation, but it must be reasonable. The division of processes can generally be carried out in the following ways:

1, tool centralized sequencing method.

This method is to divide the process according to the commonly used tools and use the same tool to process all the parts that can be completed on the part. In order to reduce the customized tool change time for stainless steel sheet metal processing, compress the idle time, and reduce unnecessary positioning errors, parts can be processed according to the method of tool concentration process, that is, in one clamping, try to use one tool to process common parts that may be processed, and then change another tool to process other parts. This can reduce the frequency of tool change, compress the idle time, and reduce unnecessary positioning errors.

2.

each part has different structural shapes and different technical standards for each surface layer, so the positioning methods are different during processing, so the processes can be divided according to the differences in positioning methods.

For parts with many processing contents, the processing parts can be divided into several parts according to their structural characteristics, such as inner shape, outer shape, curved surface or plane, etc. Generally, the plane is processed first, the positioning surface, and then the hole is processed; the simple geometry is processed first, and then the complex geometry is processed; the parts with low precision are processed first, and then the parts with high precision are processed.

3.

When the process is customized for professional sheet metal processing according to the processing accuracy, rigidity, deformation and other factors of the parts, the process can be divided according to the principle of separation of roughing and finishing, that is, roughing before finishing, and then different machine tools or tools can be used for processing; for parts that are prone to machining deformation, calibration is required, because deformation may occur after roughing, so in general, all parts that require roughing and finishing must be separated.
