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.

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.

An NC control unitincludes a touch panel display devicethrough which a barrier canceling command is input and a machining control sectionthat performs an interference check for interference between a milling tooland a chuckand jaws. When the machining control sectiondetermines that interference occurs and stops movement of a tool rest, the machining control sectionwrites 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. When the machining program including the barrier canceling command is carried out to machine subsequent workpieces, the machining control sectionomits the interference check for the process corresponding to the barrier canceling command.

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.

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.
