1, five-axis cnc machining in the clamping, pay attention to see clearly cnc machining workpiece and the name of the program sheet, the model is the same, whether the material size match, the clamping height is high enough, with calipers card number.
2, five-axis cnc machining program list to be consistent with the direction of the benchmark angle indicated in the mold, and then check whether the right 3D drawings, especially the workpiece has been drilled water, be sure to see whether the 3D drawings and the workpiece on the water are consistent, such as unknown feedback to the programmer or find the master clamps on the 2D drawings, to see whether the 2D and 3D benchmark angle is consistent.
3, the machine tool processing speed operator to strictly control, F speed and S spindle speed to adjust each other reasonably well, F speed fast relative to S spindle to speed up, in different areas have feed speed are to do adjustment. After processing, check the quality of no problem before you can get off the machine, to achieve a good processing.
4, five-axis CNC machining before processing, use the calibration table to detect whether the tool swing in the allowable tolerance range, the tool head and locking nozzle to be processed before the air gun blow clean, or wipe with a cloth before loading the tool, too dirty on the accuracy and quality of the workpiece has a certain impact.
5, reasonable with five-axis cnc machining tool processing steel, copper public light knife to strictly distinguish between the use of light knife margin to be reasonable, so that the smoothness of the workpiece and tool life will be better.
6, before processing to understand the content of the CNC machining program sheet, the program sheet must have 2D or 3D diagrams, and to indicate the "X length, Y width, Z height" six-sided data, where there is a plane to indicate the "Z" value, the operator after processing to facilitate detection Data is correct, there are tolerances to indicate the tolerance data.
7, five-axis CNC machining files to formalize the program list, including the module number, name, program name, processing content, tool size, tool feed, especially the tool clamping safety length, the margin of each program, the light knife, to specify clearly, R surface and the plane to be smooth, to be indicated on the program list, the operator in the processing to improve 0.02 ~ 0.05MM first processing, gong a few knives when Stop to see if the connection is smooth, feel by hand whether the level, if not smooth when the gong down again.
