1, processing technology
In the ordinary machining process, simplified processing can be performed regardless of positioning reference, mounting method, tool, cutting method, etc., but the data processing process is more complicated, and these factors need to be fully considered, and even the same processing Tasks, numerical control processing technology can have multiple solutions, can be a number of processing sites and processing tools as the main line of the process arrangements, the process has a variety of features, which is the difference between CNC machining process and traditional machining process.
2, clamps and fixtures
In the NC machining process, it is not only necessary to ensure the relative orientation of the coordinate of the fixture and the machine tool, but also to coordinate the dimensional relationship between the parts and the machine tool coordinate system. Moreover, the two steps of positioning and clamping need to be effectively controlled during the clamping process. In addition, due to the limited processing capability of the machine tool in the traditional machining process, it is necessary to carry out multiple installations during the machining process. Moreover, the use of special fixtures is required, which leads to higher costs for designing and manufacturing the fixtures, virtually increasing the production costs of the products. The NC machining process positioning can use the instrument to debug. In most cases, no special fixture design is needed, so its cost is relatively low.
