Abstract
A machine tool has the function of monitoring the sealing performance of a control panel. The machine tool measures temperature and humidity inside the control panel, calculates a vapor amount from the measured results, and stores the vapor amount. A vapor amount change ratio is calculated based on a currently calculated vapor amount and a previously calculated and stored vapor amount. An alert is announced when the calculated vapor amount change ratio is greater than or equal to a specific value.
