摘要： A workpiece support device includes a shaft rotatable about a shaft rotation axis of the shaft, a first support, a first reciprocating mechanism, and a first connecting rod having one end and another end. The shaft extends along a longitudinal direction of a workpiece. The first support includes a first support roller that is rotatable about a first roller rotation axis orthogonal to the shaft rotation axis and that is configured to contact the workpiece to support the workpiece. The first reciprocating mechanism has one end connected to the first support and is configured to reciprocate in a first expansion-contraction axis direction. The one end of the first connecting rod is rotatably connected to the first support. The another end of the first connecting rod is connected to the shaft such that the another end of the first connecting rod is rotatable together with the shaft.

摘要： In one aspect, a swiss-type machine tool is provided that includes a workpiece holding shaft, a workpiece supporting shaft, and a tool holder associated with the workpiece supporting shaft for holding at least one tool. The machine tool includes a drive operable to rotate the workpiece holding shaft and the workpiece supporting shaft around an axis. The workpiece holding shaft has a work holder configured to secure a workpiece to the workpiece holding shaft. The workpiece holding shaft is axially shiftable relative to the workpiece supporting shaft to adjust a position of the workpiece relative to the workpiece supporting shaft. The machine tool further includes a removable workpiece support, such as a guide bushing, configured to be releasably connected to the workpiece supporting shaft and rotate therewith. The workpiece support slidably contacts the workpiece and permits axial movement of the workpiece relative to the workpiece support.

摘要： A method for editing a machining program includes obtaining tool information specifying a tool mountable on a machine tool. A program editing window and at least one assistance window are displayed. The program editing window shows a program code of the machining program to control the machine tool. Each of the assistance window selectively shows the tool information and a control method. The tool is to be controlled according to the control method. In the program code, an insertion position at which a new code is to be inserted into the program code is specified. Selected information is selected from the tool information when the tool information is shown in the at least one assistance window. A command corresponding to the selected information is inserted into the program code at the insertion position.

摘要： A table rotation device includes a bearing assembly, a table support member, a support block, and a cooling block. The bearing assembly includes a fixed ring, a movable ring, and rolling elements provided between the fixed ring and the movable. The movable ring is rotatable about the rotation axis. The table support member is connected to the movable ring so as to fix a position of the table support member relative to a position of the movable ring. The support block is connected to the fixed ring so as to fix a position of the support block relative to a position of the fixed ring. The cooling block is connected to at least one of the fixed ring and the support block such that the cooling block is in contact with both the fixed ring and the support block. The cooling block provides a cooling passage.

摘要： A sheet metal working system includes a laser machining apparatus for processing a sheet metal in a laser machining region, a camera for photographing the laser machining region, an illuminator for illuminating the sheet metal, and circuitry configured to process an image photographed by the camera. The laser machining apparatus includes a sheet metal support member having a plate shape, the sheet metal support member having a plurality of elongated projections arranged in a first direction in a laser machining region. The sheet metal is disposed on the plurality of elongated projections. The camera is arranged such that the optical axis of the camera is oriented substantially parallel to the first direction when viewed in the height direction of the laser machining apparatus. The circuitry detects a bright region in the image as a machining available area of the sheet metal.
