摘要： A numerically controlled machine tool system having a tool transfer device which, with a change in the kind of workpieces to be machined in a numerically controlled machine tool, operates to replace successively unnecessary dedicated tools in a tool magazine of the machine tool with next to be used dedicated tools supplied to the vicinity of the tool magazine. A central processor reads out from an external memory device one of the numerical control (NC) programs corresponding to the kind of a lot of workpieces to be machined and transmits the NC program to a numerical controller. In advance of the machining of a last one of the lot of workpieces, the central processor modifies the NC program by inserting respectively into correct portions of the NC program a number of replacing command data each instructing that one of the dedicated tools in the tool magazine designated by one of the replacing command data be replaced. When the numerical controller executes the modified NC program for machining the last one of the lot of workpieces, tool replacing operations according to the replacing command data are successively carried out. Accordingly, during the machining of the last one of the lot of workpieces, the dedicated tools in the tool magazine designated by the replacing command data are successively indexed to a tool replacing position of the tool magazine and are successively replaced by the transfer device with the next used dedicated tools in the vicinity of the tool magazine.

摘要： The present invention is an automatic tool changer. The automatic tool changer is adapted to perform a tool magazine indexing operation in response to an indexing command and perform a tool changing operation in response to a tool changing command. If an indexing command is not output within a predetermined time period after completion of a tool changing operation, power to the servo motor driving the tool magazine is temporarily stopped and when the next indexing command is output, the power to the servo motor is resumed to perform the indexing operation. If a tool changing command is not output within a predetermined time period after completion of the tool magazine indexing operation, the power supply to the servo motor is temporarily stopped and when the next tool changing command is output, the power to the servo motor is resumed to perform the tool changing operation.

摘要： The present invention provides an automatic tool changer which employs a servo motor as a drive source for a tool magazine and, yet, features a minimized power consumption and a reduced steady torque of the servo motor. The automatic tool changer is adapted to perform a tool magazine indexing operation in accordance with an indexing command and then perform a tool changing operation in accordance with a tool changing command. If the next indexing command is not outputted within a predetermined time period after completion of the tool changing operation, power supply to the servo motor for driving the tool magazine is temporarily stopped and, when the next indexing command is outputted, the power supply to the servo motor is resumed for performing the indexing operation. If the next tool changing command is not outputted within the predetermined time period after completion of the tool magazine indexing operation, the power supply to the servo motor is temporarily stopped and, when the next tool changing command is outputted, the power supply to the servo motor is resumed for performing the tool changing operation.

摘要： A first NC program (NCP1) is created having, in united form for every process (MP1-MP3), tool selection commands (ATC1-ATC3) for automatically selecting tools used in the respective processes and machining comands (MC1-MC3) for machining performed by the tools. The first NC program is stored in a memory of an NC apparatus. The first NC program (NCP1) is then converted into a second NC program (NCP2) having a comand M06T.sub..quadrature..quadrature..quadrature...DELTA..DELTA..DELTA. (PTCM1-PTCM3) for holding the tool used in the next process in readiness at a standby position. Thereafter, the NC apparatus executes numerical control based on the second NC program (NCP2). During execution of the second NC program, the NC apparatus inputs, to the machine side, a tool number .sub..DELTA..DELTA..DELTA. of a tool for the next process read before the machining command (MC1-MC3) of the present process, causing an automatic tool changing apparatus to hold the tool for the next process in readiness at a standby position, and then executes machining based on the machining command of the present process.
