Abstract: 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.

Abstract: A machine tool controlled to restart automatic operation for machining a workpiece from an interrupted point after the machine tool, which has been automatically operated by NC program commands, is caused to interrupt the automatic operation. The NC program commands are classified into a plurality of main groups with respect to the contents of motions for changing the machine state of the machine tool. When the automatic operation of the machine tool restarts after the automatic operation has been interrupted halfway, an order of execution of the NC program commands is determined such that the main groups are arranged in a prescribed order of execution, for automatically generating a machine state restoration command. The automatic operation of the machine tool can restart from the interrupted point without the need for the operator to manually generate or correct a command for restoring the machine tool to its machine.

Abstract: A controller for machine tool 1 has a program analyzing section 12 for analyzing a machining program and extracting a fixed cycle command, a parameter setting section 15 for, on the basis of the extracted fixed command, determining an accuracy level being graded into a plurality of grades depending on how high machining accuracy is prioritized as compared with machining time in machining and setting parameters corresponding to the determined accuracy level and relating to control of the operation of a feed mechanism 30, and a drive control section 17 for controlling the feed mechanism 30 on the basis of the extracted fixed cycle command and the set parameters. The parameter setting section 15 calculates an arc-shaped movement trajectory of a tool moving around a virtual corner portion where two straight lines intersect with each other which corresponds to the parameters, and determines the accuracy level based thereon.

Abstract: Electronic equipment includes a GPS dongle for acquiring current location position information, and a PC for acquiring planned installation position information indicating a planned installation position of a machine tool previously registered with a server device which is a supplier-side device of the machine tool from the server device. The electronic equipment compares the acquired current location position information with the acquired planned installation position information, to determine whether or not the current location is within a predetermined range having the previously registered planned installation position as a base point. The electronic equipment determines, if it is determined that the current location is within the predetermined range having the planned installation position as a base point, whether or not a predetermined condition has been satisfied.

Abstract: A machine tool is controlled to restart automatic operation thereof for machining a workpiece from an interrupted point after the machine tool, which has been automatically operated by NC program commands output from an NC apparatus, is caused to interrupt the automatic operation. The NC program commands are classified into a plurality of main groups with respect to the contents of motions for changing the machine state of the machine tool. When the automatic operation of the machine tool restarts after the automatic operation has been interrupted halfway, an order of execution of the NC program commands is determined such that the main groups are arranged in a prescribed order of execution, for automatically generating a machine state restoration command.
