All or most processes of CNC CNC machine tool sheet metal use CNC machinery, such as CNC machine tools, CNC laser cutting machines, CNC shear machines, etc. It can achieve high product accuracy and shorten product research and development time. It can be immediately produced and manufactured from drawing to the production and manufacturing of electronic products. Suitable for small batch production and various intelligent production. CNC computer gong processing is a automated machine tool processing equipped with a program control system. The control system can logically handle programs with control codes or other symbols, and use the decoding to make the machine tool movement and processing parts. It is also called CNC or CNC machine tools. The sheet metal of CNC machines is based on the basic processing method of sheet metal parts, such as the lower feeding, bending, stretching, forming, and welding. This specification explains the process requirements of each processing method.  
 
Tab  
According to the different processing methods of the CNC machine tool, it can be divided into generals, digital rush, cutting beds, laser cutting, and wind cutting. Due to the different processing methods, the processing process of the feeding is also different. The sheet metal feeding method is mainly rushing and laser cutting.  
 
Bend kneebend  
When the material is bent, the rounded corner area is stretched on the outer layer, and the inner layer is compressed. When the thickness of the material is certain, the smaller the inner R, the more severe the stretching and compression of the material; when the stretching stress of the outer rounded corner exceeds the extreme strength of the material, cracks and breaks will be produced. Design should avoid too small curved rounded corners radius.  
 
Stretch extrude  
The circular radius of the bottom and straight wall of the non -protective stretch parts of the CNC machine tool should be greater than the thickness of the plate, that is, R1 ≥ T. In order to make the stretch more smooth, generally take R1 \\u003d (3 ~ 5) T. The radius of the large rounded corner should be less than or equal to 8 times the thickness of the plate, that is, R1 ≤8T. Due to the different sizes of stretching parts, the thickness of the material after stretching changes. Generally speaking, the center of the bottom maintains the original thickness, the material at the bottom of the bottom of the bottom is thinner, the material is thicker near the convex edge, and the material of the rounded corner of the rectangular stretching parts becomes thicker.
