In sheet metal processing, there are several main processing methods for numerical punching:
1. Single punching, which means completing multiple punching processes including arc distribution, grid holes, etc. in a single operation;
2. Continuous punching is divided into two directions: in the same direction and in multiple directions. Continuous punching in the same direction is mostly processed by overlapping molds, which is most suitable for processing elongated holes; Multi directional continuous punching is most suitable for using small molds for large hole machining;
3. Silkworm processing, using small circular molds and small step sizes for continuous arc punching processing;
4. Single or continuous forming processing, single forming is a sheet metal processing that involves shallow stretching and one-time forming based on the nature of the mold. If the forming is larger than the mold size, continuous forming processing is required;
