A robot control apparatus controls a robot having six drive axes and a drive axis as an additional axis. The control apparatus includes a display control part which controls a display of a display part. The display control part displays, on the display part, a first picture which displays an operation program including an operation statement and a second picture which displays a state of the drive axes included in the operation statement. The display control part displays the operation statement including a state of the additional axis without including a state of the six drive axes in the first picture.

A numerical control device includes an NC-machining-program reading unit to read an NC machining program, a machining-removal-shape generation unit to generate a machining removal shape by a block of the NC machining program, a tool-data search unit to search for tool data to be used in the NC machining program, and a machining-finished-shape generation unit to generate a machining finished shape from the machining removal shape generated by the machining-removal-shape generation unit. During editing of the NC machining program, the machining removal shape and the machining finished shape can be confirmed sequentially by the block.

This control device for a machine tool is provided with: a display unit that displays information relating to a machine tool; a display control unit that controls the display of the display unit; and a storage unit. A display setting of the display unit that corresponds to an operation of an operator or the condition of the machine tool is stored in advance in the storage unit. The display control unit acquires an operation of the operator or the condition of the machine tool, reads the display setting corresponding to the operation of the operator or the condition of the machine tool from the storage unit, and changes the display of the display unit on the basis of the display setting.

A waveform display device is provided that extracts data of a required portion from data outputted from a numerical control. A waveform display device includes: a data acquisition part that acquires a predetermined type of data from output data outputted from a numerical control; a condition determination part that determines a start condition and end condition for extracting partial data from the predetermined type of data based on information from the numerical control; a data extraction part that extracts the partial data corresponding to the start condition and end condition from the predetermined type of data; and a waveform display part that displays the partial data extracted as a waveform.

A numerical control device stops automatic operation after machining of a specific part without the need to manually modify a machining program or to perform macro computation. The numerical control device includes a program analysis section that, upon executing a command program for continuously machining a plurality of parts, analyzes the command program, an analyzed program execution unit that executes the command program analyzed, a program stop condition setting section that sets a program stop condition in the command program based on a machining stop condition specified by a user, a program stop determining section that determines whether an execution block of the command program satisfies the program stop condition based on an analysis result, and a program stop requesting section that, when it is determined that the execution block satisfies the program stop condition, outputs an execution block stop request to the analyzed program execution unit.
