Broken tool detection – plunge checking
(subroutine L9863)
Subroutine L9863 is used to check for breakage of cutting tools. The
Broken tool cycle uses a plunge check, where the tool is moved into
and out of the laser beam in the axis used for length setting. The
cycle can also check for a ‘long tool’ condition, where the tool has
possibly pulled out during machining.
Typically, a tool needs to be checked after a machining operation to
verify that it is not broken before the next tool is selected.
