Numerical control stamping is a very important part in sheet metal processing. Compared with the traditional punching machine, the processing efficiency of numerical control stamping has been improved a lot. Automotive stamping parts also play a significant role in improving the problems existing in batch production of sheet metal parts and complex sheet metal parts processing.

In sheet metal processing, there are several main processing methods of numerical punching

1. Single punch, that is to say, single punch includes arc distribution, grid hole and so on;

2. Continuous punching can be divided into the same direction and multi direction. The continuous punching in the same direction is mostly processed by overlapping dies, which is suitable for processing long holes; the continuous punching in multi direction is suitable for processing large holes with small dies;

3. In the process of cannibalism, small circular die and small step are used for arc continuous punching;

4. Single or continuous forming processing, single forming is the sheet metal processing of shallow drawing one-time forming according to the nature of the mold. If the forming is larger than the size of the mold, the continuous forming processing method is needed;

5. Array forming is suitable for processing multiple workpieces on large plate. The type of workpieces can be the same or different.

Sheet metal cutting is a process of sheet metal processing. According to different sheet metal requirements, the cutting methods are different. The following are the common methods of sheet metal cutting:

1. Cutting, that is, use the Shearer to cut out the length and width of the expanded drawing. If there is punching and corner cutting, then turn the punch combined with die punching and corner cutting.

2. Laser cutting is to use laser cutting method to cut out the structural shape of the flat part on an iron plate.

3. Punch blanking, that is to say, the stamping forming of the flat plate structure after the parts are unfolded in one or more steps by punch. It has the advantages of short working time, high efficiency, and can reduce the processing cost. It is often used in mass production.

4. NC cutting, NC cutting, the first thing to write NC machining program. That is to use programming software, the development of the drawing will be written into CNC cutting machine recognizable program. According to these procedures, auto parts can be punched out on an iron plate step by step.

CNC cutting is a common method in sheet metal processing, which is widely used in CNC cutting. Considering that the thickness of processing materials is less than 6 mm, the most commonly used method is CNC plasma cutting
