Methods and apparatus for detecting machine tool window airtightness includes an airtight state detector, having a sensor detecting the pressure in a space of the window, and a judging section for determining appropriateness of the airtight state of the space based on a pressure value from the pressure sensor and outputting a judgment result. Pressure in the window space, which initially may be pressurized or pressure-reduced, is detected intermittently by the pressure sensor, and the judging section determines appropriateness of the airtight state of the window on the basis of a variation state of the detected pressure.

Method and apparatus for detecting airtight state of machine-tool window

Electronic equipment, including a GPS dongle and a PC, compares an acquired current location position of the electronic equipment with an acquired planned installation position of a machine tool to determine whether or not the current location position is within a predetermined range from the planned installation position. Further, the electronic equipment determines, if it is determined that the current location position is within the predetermined range from the planned installation position, whether or not a predetermined condition has been satisfied. The electronic equipment also performs, if it is determined that the predetermined condition has been satisfied, information input processing on the machine tool to remove activation restriction on the machine tool. In this manner, the electronic equipment can prevent illegal removal of activation restriction on the machine tool.
