When doing cnc machining of workpieces, it often encounters the problem of machining center collision, which not only affects the processing efficiency, but may even destroy the workpiece, and is more likely to form personal events. So what are the reasons for the collision of the cnc machining center?
(1) The knife input error is a very common collision machine.
1, coordinate offset 60 input error
2, the workpiece coordinate G54 and other input errors
3, length G43 compensation H input error or call error
4, radius G41 compensation D input error or call error
5, G40 or G49 or G80 input error
(two) error manipulation
1. Open the wrong program
2, the wrong knife
3, mistake the machining coordinates
4, boot did not return to the origin
5, hand wheel or manual target mistakes
(3) Unique procedures can also cause collisions
1. There is more than one change of the tool inside the program (the machine will crash due to a mistake in the tool)
2. The program returns to the lower cutting point after the knife is cut off at the mechanical reference point (collision plate or screw)
3, the program starts at the beginning of the diagonal line knife (Z appears in front of H)
4, the height of the safe is lower than the bottom (clamping plate or nut)
Have you remembered the above reasons? I hope everyone pays more attention when they work.
