1. Use cnc to process the tool reasonably. The smooth knife for processing steel and copper should be strictly used, and the allowance of the smooth knife should be reasonable, so that the smoothness of the workpiece and the service life of the tool will be better.
2. Before cnc processing, use the calibration table to check whether the tool can swing within the allowable tolerance range. The tool head and lock nozzle should be blown clean with an air gun before processing, or wiped with a cloth before installing the tool. Too dirty will affect the workpiece The accuracy and quality have a certain impact.
3. When clamping, pay attention to see whether the title and type of the CNC machined workpiece and the program sheet are the same, whether the material size can be matched, whether the clamping height is high enough, and the number of calipers used.
4. The cnc processing program must be inconsistent with the reference angle direction marked by the mold, and then check whether the 3D map is correct, especially for the workpiece that has been drilled to transport water, you must clearly see the 3D map and the workpiece on it. Whether the water is not compatible, if you are not sure, you should promptly respond to the programmer or find a fitter to check the 2D drawing to see if the 2D and 3D reference angles are not compatible.
5. The program list of the cnc processing file should be normalized, including the model number, title, program name, processing content, tool size, feed amount, especially the safe length of tool clamping, the reserved allowance for each program, and the smooth knife. , It should be clearly marked, the center of the R surface and the plane should be connected in the same way, and it should be marked on the program sheet. The operator should advance 0.02~0.05MM to process first, and stop after a few knives to see if it can be connected. If it is smooth, you can feel it with your hand to see if you can lift the stage. If it is not smooth, then lower the gong.
6. Before processing, it is necessary to understand the content of the CNC processing program list. There must be a 2D or 3D diagram on the program list, and the hexagonal data of X length, Y width, and Z height should be marked. If there is a plane, the Z value should be marked. It is convenient for the operator to check whether the data is correct before processing, and if there is a tolerance, the tolerance data should be indicated.
7. The operator should strictly control the machining speed of the machine tool. The F speed and the S spindle speed should be properly scheduled for each other. When the F speed is fast, it should be faster than the S spindle. The feed speed in different areas should be scheduled. After processing, you can get off the machine before checking that there is no problem with the quality, so as to achieve a complete processing.
