1. For cnc machine metal, when the tool moves to the surface of the workpiece by 30~50mm, it is necessary to confirm that the residual axis of the coordinate axis and the coordinate values of the X and Y axes are synchronized with the mode while maintaining the feed. 2. For some tools that require testing tools, a "gradual" approach can be used. For example, the length of the borehole can be tested. After the test is passed, the entire length can be reached. The tool data using the tool radius compensation function can be modified from large to small. 3. In the trial cutting and machining process of the machining center, after changing the tool, the tool length should be re-measured and the tool compensation value and tool compensation number should be modified.
4. When searching the program, pay attention to whether the position of the cursor is reasonable and accurate, and observe whether the tool coordinates and the movement direction of the machining center are correct. 5. After modifying the machining center program, carefully calculate and carefully check the modified workpiece. 6. When performing manual feed and manual continuous feed operations, you need to check whether the position selected by each switch is correct, find the positive and negative directions, and then press the button before cnc machine metal operation.
