The development of things needs to revolve around a central point, and CNC machining parts drawings and programs occupy a high position in factory processing. What is the position of the CNC machining parts drawing and program: look at the dimensions on the drawing, because this involves the processing of qualified. Check if the materials used need to be replenished to know if the material is suitable for processing. After that, you need to look at the drawings and determine the processing route, because you have to consider how to process. Every processing process needs technical support, that is, the previous drawings and procedures. If these can’t be done, then it will affect the last step, so it should be thoroughly studied on the drawings. The problems that should occur, and where they are prone to problems, should be identified in time to ensure that the subsequent procedures, once the program is determined, can not continue, that is, can not be changed casually, now use It’s all automation, that is, when the program is edited, it can’t be changed at will, and it can also be stored, because if it is similar, only a small change is needed. From many aspects, it can be seen that CNC machining parts drawings and programs are very important. If a program has an error and subsequent errors will occur, it will have serious consequences. So when looking for a processing plant, this is also a problem to be considered.
