Ключевые слова: ЧПУ, станок
Numerical control processing technology is derived from conventional processing technology and is an organic combination of conventional processing technology, computer numerical control technology, computer-aided design and auxiliary manufacturing technology. Due to the continuous development of technology, more and more parts need to be precisely processed in modern manufacturing, and the requirements for processing accuracy and surface complexity of the workpiece are also getting higher and higher. Поэтому, CNC machining has received widespread attention, but in terms of cost savings, CNC machining is still more expensive than traditional machining. Now we will introduce the difference between CNC machining and traditional machining technology.

1. Processing technology
In the ordinary machining process, whether it is positioning datum, clamping method, инструмент, cutting method, и т. д., it can be simplified. Однако, the data processing technology is more complicated, and these factors need to be fully considered. And even for the same processing task, the CNC machining process can have multiple solutions, and multiple processing locations and processing tools can be used as the main line for process arrangements. The process has diversified characteristics, which is the difference between CNC machining process and traditional machining process.

2. Clamping and fixture
In the CNC machining process, not only the coordinate directions of the fixture and the machine tool must be relatively fixed, but also the dimensional relationship between the part and the machine tool coordinate system must be coordinated. Более того, the two steps of positioning and clamping need to be effectively controlled during the clamping process. Более того, under the traditional machining process, due to the limited machining capacity of the machine tool itself, it is necessary to perform multiple clamping during the machining process. Более того, it is necessary to use special fixtures, which leads to higher costs in the design and manufacture of fixtures, and virtually increases the production cost of products. The positioning of the CNC machining process can be debugged by the instrument. In most cases, no special fixture design is required, so the cost is relatively low.

3. Tool
In the process of processing, the choice of tools needs to be determined according to the processing technology and processing methods. Especially in CNC machining, the use of high-speed cutting is not only conducive to the improvement of machining efficiency, but also the machining quality can be guaranteed, effectively reducing the probability of cutting deformation and shortening the machining cycle. Поэтому, the demand for cutting tools has further increased under the guidance of cutting.

В настоящий момент, there is also a dry cutting method. This cutting method performs cutting without adding cutting fluid or only adding a small amount of cutting fluid, so the tool needs to have good heat resistance. Compared with ordinary machining technology, CNC machining technology has higher requirements on the performance of cutting tools.
