Patent number: 10168689Abstract: A machine tool (1) includes a tool information storage (9) storing therein used tool information for, when an NC program execution part (5) executes an NC program, specifying a tool used for machining, and a magazine operation panel (18) includes an announcement part (18b) for announcing an alarm to an operator. When receiving an operation signal from an input part (18a) while the NC program execution part (5) is executing an NC program, a tool change control part (11) checks the used tool information stored in the tool information storage (9), and in the case where a tool held by a tool pot (17a) corresponding to the operation signal is not used for machining, moves the tool pot (17a) to a tool attachment/detachment position (17c), and in the case where the tool is used for machining, causes the announcement part (18a) to announce an alarm indicating that it is unavailable.Type: GrantFiled: May 25, 2015Date of Patent: January 1, 2019Assignee: DMG Mori Co., Ltd.Inventors: Takayuki Nishioka, Tetsushi Asada

Patent number: 9962800Abstract: To provide a tool changer of a machine tool that makes it possible to surely execute machining as designated in a machining program without any need for the editing of the machining program or the replacement of tools and without complicating the device structure. The tool changer 11 includes a tool correspondence table A showing a correspondence relation between a program-designated tool T0001 designated in a machining program O0001 and an actual use tool T0003 actually used according to the machining contents designated in the machining program, wherein the actual use tool corresponding to the program-designated tool is found by using the tool correspondence table A and the found actual use tool is decided as a subsequent process tool.Type: GrantFiled: November 3, 2011Date of Patent: May 8, 2018Assignee: DMG MORI SEIKI CO., LTD.Inventors: Takayuki Nishioka, Yoshihiro Takiguchi

Patent number: 5471794Abstract: An external door body is formed of first and second guide grooves for gripping left hand and right hand edges of a front panel, and an arcuate receiving groove for gripping an upper edge of the front panel. The front panel is inserted into these grooves, and a stopper acting as a closing device is finally attached to a bottom portion of the external door body to prevent the front panel from falling off. At the installation, the front panel need not be forcibly folded, so that the work can be made easily while eliminating the damage of the front panel.Type: GrantFiled: April 15, 1994Date of Patent: December 5, 1995Assignee: Fuji Electric Co., Ltd.Inventor: Takayuki Nishioka
