age
If a tool breaks during machining, the machine will not
recognize this immediately. Instead, the spindle will
continue to move with the broken tool. The tool
breakage will be recognized upon the following
events:
The next regular tool change
n
A tool breakage can be caused by the following:
The tool was damaged or worn
n
The tool was put into the wrong tool position or
n
was manually inserted into the spindle at the
wrong time. As a consequence, it was not suitable
for the processing step.
The distribution of the objects in the blank ("nest-
n
ing") was not correct.
If a tool breaks, do the following:
1. Open the working chamber door.
2. Remove all parts of the broken tool from the work-
ing chamber and the collet chuck.
3. Re-add the tool to the virtual ATB and virtual tool
magazine in DENTALCNC.
4. If the spindle picked up the tool from the tool
magazine, check if the tool was inserted into the
correct position. Insert a spare tool into the correct
position in the tool magazine.
5. If you manually inserted the tool into the collet
chuck, check if the broken tool corresponds to the
tool type which you were prompted to insert. Have
a correct spare tool ready.
6. Close the working chamber door.
7. Resume the job.
DENTALCNC allows you to resume the job from
the last tool change. For more information, see
the corresponding documentation.
