1.2然后材料会被送到数控冲床/切割机，进行冲孔/切割工序。在此工序，需要为被加工的零件编制NC（Numerical Control ）代码。现在大多数机床厂商都会提供自动编程软件（国内的厂商几乎都是跟国外的此类软件公司合作，进行OEM销售，因此它们并没有自己的软件研发队伍），因此极大地方便了编程工程师。冲压/切割编程工程师所要考虑的因素是板材利用率、刀具、效率、精度等问题。冲压/切割完成后，零件便被去除微连接，接着将被送到折弯机折弯。
There is not much difference between the operation of the sheet metal factories and the general manufacturing enterprises. Here we only introduce the manufacturing process of the products in the workshop.
Usually, the three most important steps in a sheet metal factory are scissors, punching, cutting and folding.
1.1 the first thing to do is blanking (also known as blanking) process. Usually, the field workers will cut the appropriate size of the material according to the expansion plan provided by the technical department. If a punching machine is used, the dead zone of the clamp must be taken into account. After the blanking is finished, the worker will mark the material on the surface of each material with a marker.
Note: there are also some factories that do not have such processing steps, directly typesetting on standard sheets, and then directly stamping / cutting.
1.2 then the material will be sent to the CNC punching / cutting machine for punching / cutting process. In this process, NC (Numerical Control) code is needed for the parts to be processed. Now most machine makers will provide automatic programming software (the domestic manufacturers are almost all working with such software companies abroad, OEM sales, so they don't have their own software R & D teams), so it's a great place for programming engineers. The factors to be considered by stamping / cutting programming engineers are the utilization ratio, cutting tools, efficiency, accuracy and so on. After stamping / cutting, the parts are removed and connected to the bending machine.
1.3 in the bending process, the main considerations are tool selection, bending sequence, bending compensation, bending interference and so on. Usually there will be a random sale of bending programming software, but most of the domestic CNC bending machine or artificial programming, often too much relying on the experience of the teacher Fu, on the other hand, the domestic manufacturing process requirements relative to foreign countries have a certain distance, so the efficiency is not improved, the performance of CNC bending machine is not. Play to the extreme.
1.4 finally, according to the product situation, welding, grinding, painting, assembling, packaging and other processes may be carried out.
