Abstract: A machining program editing assist apparatus includes a display controller. While the display objects are being displayed in either one of the program data display area and the process list display area, the display controller decides that a designated display object of the one of the display areas is the display object designated by the display objects of the one of the display areas and a specific point, differentiates the designated display object from the other display objects in the one of the display areas, decides that a designated display object of the other of the display areas is the display candidate of the other of the display areas, includes the designated display object in the display objects of the other of the display areas, and differentiates the designated display object from the other display objects in the other of the display areas.

Abstract: A machining program editing assist apparatus includes a display controller. When a specific portion on a shape display area is designated via an input device, the display controller allows a display candidate specified by the specific portion to be displayed as a designated display target of the shape display area, and allows at least one portion of data being among at least one display candidate of a program data display area and sectioned by a machining process constituting the at least one machining process and corresponding to the designated display target of the shape display area to be displayed as a designated display target of the program data display area on the program data display area in a state in which a beginning of the at least one portion of data is set to a display start position of the program data display area.

Abstract: A device includes a CPU and a touch-panel display. In a first display mode, when control functions that belong to a first level are assigned to menu switches of a plurality of menus, one of the menus is displayed. In a second display mode, all the menus are displayed. A change switch is provided in a menu display selection area, and includes a plural-row mark to indicate that a plurality of menus exist at the first level. The CPU switches between the modes to display one or all menus in the menu display selection area. When a plurality of menus exist at the first level, the plural-row mark is displayed; otherwise, the plural-row mark is erased. When the menus are displayed in the second display mode, the plural-row mark is lit. When the menu is displayed in the first display mode, the plural-row mark is unlit.

Abstract: An NC control unit 100 includes a touch panel display device 155 through which a barrier canceling command is input and a machining control section 160 that performs an interference check for interference between a milling tool 70 and a chuck 58 and jaws 60. When the machining control section 160 determines that interference occurs and stops movement of a tool rest 54, the machining control section 160 writes the barrier canceling command that commands cancelation of the interference check for a process of a machining program where the interference has been determined based on manipulation of the display device 155. When the machining program including the barrier canceling command is carried out to machine subsequent workpieces, the machining control section 160 omits the interference check for the process corresponding to the barrier canceling command.

Abstract: A simulation control section 210 of an NC machining simulation apparatus 10 computes a movement path of a mechanical element when performing simulation. A ring buffer 270 memorizes the movement path of the mechanical element. In response to a replay instruction, the simulation control section 210 reads the movement path from the ring buffer 270. The simulation control section 210 then displays the mechanical element on a display device 190 as a solid model based on the movement path for replaying the simulation.

Abstract: An NC device includes an accumulation portion for accumulating a report-item corresponding to a report-requiring situation that occurs in a machine. A voice generator control section of the device operates a voice generator to generate a voice for announcing a report-item accumulated by an accumulation portion if a determination portion determines that a operator-in-range information has been generated or in response to a request produced by a request portion. Contrastingly, the voice generator control section does not permit the voice generator to generate the voice if the determination portion determines that the operator-in-range information has not been generated. In this manner, the voice generation is performed efficiently and the operator is reliably informed of the report item.

Abstract: The NC device of the machining center has the data memory for storing exchange history and data concerning a tool therein when the tool has been manually exchanged. When the data concerning the tool is updated, the data memory also stores update history. The main control unit determines whether the tool is changed on the basis of at least either of the exchange history and the update history. On the basis of a determination result, the main control unit controls the spindle head moving unit to stop the tool as well as allows a caution about the tool to be displayed on the display unit.

Abstract: An automatic programming apparatus includes a process division control section, which automatically divides a machining process executed to obtain a predetermined product shape from a material shape of a workpiece. The process division control section computes a removal shape, which is a shape to be removed from the material shape when executing the machining process, based on the material shape and the product shape. The process division control section defines a reference machining boundary that intersects a reference axis defined on the product shape and divides the volume of the removal shape into two equal parts. The process division control section defines, on the removal shape, a process division boundary that intersects the reference axis based on the reference machining boundary and the profile of the product shape. The machining process is divided into a first process and a second process with the process division boundary.

The complex tool is registered in a tool data file as a plurality of virtual tools capable of executing corresponding machining operations. The virtual tools include a turning tool and a milling tool. In the tool data, the angle in a B-axis direction at which the tool is positioned when the virtual tool is used is stored as a B-axis angle for each virtual tool. The tool data of the corresponding virtual tool is read out from the tool file on the basis of the programmed machining instructions, and the B-axis angle is set on the basis of the tool data so as to execute machining.

Abstract: A complex tool has a main body and a turning tool provided at an outer periphery portion of the main body. The turning tool is capable of machining on a rotating workpiece without rotating itself. An insert installed on the turning tool has a top end which contacts a workpiece by projecting a predetermined amount outside the main body's outer peripheral face. It also projects a predetermined amount from a top end portion of the main body in a direction of an axial center of the tool. The complex tool also has a rotating tool for machining by rotating itself. The rotating tool accomplishes machining corresponding to an axial center of the main body.
