When doing CNC machining, we often encounter the problem that machining center collides with the machine, which will not only affect the machining efficiency, but also may destroy the workpiece, more likely to form personal events. So what are the causes of CNC machining center collision?
（1） Cutter compensation input error is a common cause of collision
1. Coordinate offset 60 Li input error
2. Input error such as workpiece coordinate g54
3. Length G43 compensates for H input error or call error
4. Radius G41 compensates for D input error or call error
5. G40 or G49 or g80 input error
（2） Error manipulation
1. Wrong procedure
2. Install the wrong knife
3. Wrong machining coordinates
4. Power on without returning to the original point
5. Handwheel or manual target error
（3） Unique programs can also cause crashes
1. There is more than one tool change in the program (it will collide with the machine due to tool compensation error)
2. The program will return to the cutting point (pressing plate or screw) after cutting at the mechanical reference point
3. The program starts with a slash (Z appears in front of H)
4. Lower safety height (pressing plate or nut)
Do you remember the above reasons? I hope you will pay more attention when you work.
