Why is the cnc machining processing parts inefficient?

news

Facing the problems in trade, expanding domestic demand, stabilizing our customers, and ensuring the high precision and high efficiency of each batch of parts processing, this is what each of us should do. However, in the production of parts, there is often a high rate of scrap. It wastes raw materials and delays the delivery time of customers. Where is the reason? Below we analyze the process flow of CNC milling machine in the machining of mechanical parts:
First, the programming steps should be divided before programming, what is the process? The process of making raw materials into products is called a process. The entire process consists of several processes, which are cnc machining processes that are continuously performed by one or a group of workers at a work site. The process can be divided into several steps. For the CNC milling machine, one step refers to one continuous cutting.
Second, the cnc machining of the workpiece to the workpiece requires multiple processes, and sometimes it takes several steps in one process. For example, a template needs to be roughed, semi-finished, finished, drilled, reamed, and reamed. It can be arranged in one process and divided into several steps by a CNC milling machine.
Generally, the workpiece is machined on a CNC milling machine. The whole process should be completed in one setup as much as possible.
(1) Divide the process according to the principle of the first hole and the back hole. When machining a workpiece with a hole in the face, in order to improve the machining accuracy of the hole, the surface should be machined first and then the hole should be machined.
(2) Divide the process by roughing and finishing. For workpieces with high machining accuracy requirements, coarse and fine machining should be carried out separately, so that various deformations caused by roughing can be restored, and finishing should not be arranged immediately after roughing.
(3) Divide the process according to the tool used. CNC milling machines, especially CNC milling machines without a tool magazine, in order to reduce the number of tool changes, you can use the same process to process the same part on the workpiece and then use another knife. Processing other parts.
