Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
1 . A machine tool comprising: a control panel; a temperature sensor and a humidity sensor that measure temperature and humidity inside the control panel, respectively; a vapor amount calculation unit that calculates a vapor amount based on the temperature and the humidity; a vapor amount storage unit that stores the vapor amount; a vapor amount change ratio calculation unit that calculates a vapor amount change ratio based on the vapor amount calculated by the vapor amount calculation unit and the vapor amount stored in the vapor amount storage unit; a vapor amount change ratio threshold setting unit that retains a threshold that is set in advance; a vapor amount change ratio comparison unit that determines whether or not the vapor amount change ratio is greater than or equal to the threshold; and an alert announcement unit that announces an alert when the vapor amount change ratio is greater than or equal to the threshold. 2 . The machine tool according to claim 1 , wherein the vapor amount change ratio calculation unit calculates the vapor amount change ratio using an average of the vapor amounts per prescribed time instead of the vapor amounts. 3 . The machine tool according to claim 1 , further comprising: a door opening/closing detection unit that detects whether a door of the control panel is opened; and a vapor amount resetting unit that temporarily stops the operation of the vapor amount calculation unit to reset a content stored in the vapor amount storage unit when the opening of the door is detected. 4 . The machine tool according to claim 1 , further comprising a power supply monitoring unit that detects whether a power supply of the machine tool is turned ON/OFF, wherein the operation of the vapor amount calculation unit is stopped for a prescribed time when the power supply monitoring unit detects ON/OFF of the power supply.
