CNC machining safety precautions

CNC machining generally refers to precision machining, CNC machining lathes, CNC machining milling machines, CNC machining boring and milling machines,

Now many aluminum alloy housings are processed by CNC. Do you know the secret of how to use machining technology safely?

1. Use computer simulation system
   With the rapid popularization of contemporary computer technology and the continuous expansion of CNC machining teaching, there are more and more CNC machining simulation systems and their functions are becoming more and more perfect. So this technology can be used to check the program: observe the movement of the tool to determine whether a collision is likely to occur. Use the simulation display function that comes with the machine tool. Generally speaking, CNC machine tools have advanced graphic display functions. After entering the program, you can call the graphic simulation display function to observe the tool’s movement trajectory in detail and check whether the tool collides with the workpiece or fixture.
2. Use the locking function of CNC machining
   Generally, CNC machine tools have a locking function (full lock or single-axis lock). After entering the program, lock the two axes and judge whether a collision will occur based on the coordinate values ​​of the two axes. The application of this function should avoid operations such as tool change, otherwise the program will not pass.
3. The coordinate system and tool compensation settings must be correct
   When starting CNC machining, remember to set the machine reference point. The CNC machining work coordinate system should be consistent with R when programming, especially in the seven-axis direction. If you accidentally make an error in operation, the milling cutter is likely to contact the workpiece. In addition, the tool length compensation setting must be correct. Otherwise, it is either an empty process or a collision.
4. Use the dry run function of CNC machining
   This function can be used to check the correctness of the tool path. After the program is entered into the machine tool, the tool or workpiece can be installed and the dry run button can be pressed. At this time, the spindle does not rotate, and the worktable automatically runs according to the program trajectory. At this time, you can find out whether the tool can contact the workpiece or fixture. However, in this case, it must be ensured that the tool cannot be installed when the workpiece is installed; the workpiece cannot be installed when the tool is installed, otherwise a collision will occur.
