Abstract: A display device for a machining program has a function of displaying a modal state. The display device includes a program analysis unit that inputs the machining program and that identifies an attention block in the machining program, a modal effective range analysis unit that identifies a modal state that is effective in the attention block and an effective range of the modal state, and a modal effective range display unit that visually displays the effective range of the modal state along with the machining program.

Abstract: A numerical controller for correcting a deviation amount corresponding to a difference between a theoretical value and a measured value of a workpiece includes a machining unit for storing a machining path of the workpiece and an effective offset number during machining of the machining path in association with each other, a measurement unit for storing a deviation amount applied to the workpiece and a measurement point at which the deviation amount is detected in association with each other, and a correction unit for reflecting the deviation amount to the offset number corresponding to the machining path around the measurement point.

Abstract: A measurement result analysis device includes: a measurement result classification unit that classifies measurement result information on the basis of the measurement result information in which measurement results of a machine tool and measurement attributes of the measurement results are correlated; a measurement result extraction unit that acquires related information including classifications of the measurement result information on the basis of a content of an analysis result for which it is instructed to output with respect to the measurement result information; and an analysis result display unit that outputs an analysis result for the measurement result information on the basis of the related information acquired by the measurement result extraction unit.

Abstract: A numerical controller stores, among executed programs, a program applicable to a preset favorite condition in a specified storage area. The numerical controller then stores, based on execution history information on the program, the program applicable to the preset favorite condition in the storage area. The numerical controller then classifies the program stored in the storage area based on contents of the program, and displays the program stored in the storage area based on a result of classification.
