Factors That Should Be Considered When Choosing a CNC Machining Method

Ⅰ. The processing methods of the surface of the CNC machining parts

The machining method of the surface of a CNC machined part firstly depends on the technical requirements of the machined surface. However, it should be noted that these technical requirements are not necessarily the requirements specified in the part drawing, and sometimes may be higher than the requirements on the part drawing in some respect due to technological reasons. If the benchmarks do not overlap and increase the processing requirements for the surface of some CNC machined parts, or because they are used as benchmarks, higher processing requirements may be put forward.

After clarifying the technical requirements for the surface of each CNC machined part, you can select the final processing method that can guarantee the requirements based on this, and determine the number of steps and the processing method required for each step. The selected machining method of CNC machining parts should meet the requirements of part quality, good machining economy and high production efficiency.

Ⅱ. Factors influencing the choice of CNC machining

The machining accuracy and surface roughness that can be obtained by any CNC machining method has a considerable range, but only a narrow range is economical. The machining accuracy in this range is the economic machining accuracy. For this reason, when choosing a processing method, the corresponding processing method that can obtain economical processing accuracy should be selected.

2. To consider the nature of the materials of the CNC moulding.

3. The structural shape and size of the CNC machined parts should be considered.

4. To consider the requirements of productivity and economy. In mass production, high-efficiency advanced technology should be used. It can even fundamentally change the manufacturing method of the blank, which can reduce the labor of machining.

5. The existing equipment and technical conditions of the factory or workshop should be considered. When choosing a CNC machining method, you should make full use of the existing equipment, tap the potential of the enterprise, and give play to the enthusiasm and creativity of the workers. However, consideration should also be given to continuously improving the existing processing methods and equipment, adopting new technologies and improving the level of craftsmanship.
