Analysis of Process Processing Stage in CNC Machining

As the 1 advanced processing method, CNC Machining is widely used in the aviation industry, ship industry, electronics industry and other high-precision, complex parts processing production. In CNC machining, it is a complex and rigorous process from part drawings to processing qualified parts. A problem at a certain point in each stage will interrupt the process. The following is divided into three stages with specific processing examples to analyze some key factors in the process of CNC machining, so that we can deepen our understanding of CNC machining and help the processing and production.

Process stage

Most of the CNC Machine Tools used in general do not have the ability to process. The purpose of CNC machining process is similar to that of ordinary machine tools. However, because every 1 of the processing process of CNC machine tools must be predetermined, the processing is automatically completed. Therefore, compared with the process preparation of ordinary machine tools, it has its own characteristics.

1.1 tool setting and tool change

When machining parts by ordinary machine tools, the position relationship between the tool and the workpiece is established by the cooperation of the measuring tool and the hand wheel. If the tool position is not correct, it can be adjusted by the operator at any time. And CNC machining, a clamping, there are more than one tool involved in processing, in order to establish the various knife type and other parameters input to the computer, the computer through coordinate transformation, so that each tool and the workpiece to establish a corresponding relationship. For ordinary machining, the knife problem is not considered as an important factor. For CNC machining, as long as the use of program processing, you must set the knife, otherwise serious consequences will occur. Ordinary machining tool change is often controlled by operating feeling, and CNC machining must seriously consider the tool change position to prevent collision.
