In the first stage, it is determined whether the tool has been removed. If the tool has been removed, the installed tool measurement request/memory 9 issues an alarm for a tool installation request and the correction flag is turned off. Next, in the second stage, it is determined whether the tool has been installed. If no tool is attached, feedback is given to the stage before the first stage. If the tool is attached, it is determined in the first stage whether the tool has been measured. If tool measurement is not performed, the correction flag remains OFF, and at the same time as the alarm continues, feedback is sent back to the stage before the first stage. If the tool measurement has been performed, the correction flag is turned on by the measurement correction completion signal/memory 11 in the second step, and the alarm is stopped. In the tool measurement value, the correction value calculated by the offset calculation means 12 is written in the X and Z columns of the tool file 13, and the process ends. If the tool is not removed in the first stage, the process ends.
