It's easy to look at a part, but it's not.
You may not know how complicated it is to process a part, different tools, different cutting methods, different parameter settings, and so on.
The division of NC machining processes can generally be carried out in the following ways:
The main results are as follows: (1) the parts which are prone to machining deformation need to be corrected because of the possible deformation after rough machining, so generally speaking, the processes of rough and finish machining should be separated.
(2) for parts with many machining contents, the machining part can be divided into several parts according to its structural characteristics, such as inner shape, shape, curved surface or plane, etc.
Generally, the plane and positioning surface are processed first, and then the holes are machined; the simple geometric shapes are processed first, and then the complex geometric shapes are processed; the parts with lower precision are processed first, and then the parts with higher precision are processed.
(3) the tool centralized sorting method is to divide the process according to the tool used, and use the same tool to process all the parts that can be completed.
Use the second knife and the third to complete other parts that they can do.
In this way, the tool changing times can be reduced, the space time can be compressed, and the unnecessary positioning error can be reduced.
To sum up, it is understood that when dividing the process, it must be flexibly mastered according to the structure and technicality of the parts, the function of the machine tool, the number of CNC NC machining contents of the parts, the number of installation times and the production organization of our unit.
It is also suggested that the principle of centralized process or the principle of decentralized process should be adopted, which should be determined according to the actual situation, but must strive to be reasonable.
