Abstract: The present invention addresses the problem of providing a display device with which it is possible to display a location in a machining path at which a step occurs that is large enough to affect machining precision without actual machining, and to be able to accurately and at low cost predict the occurrence of the step in the machining path. The problem can be resolved with a display device with which: time-series data is acquired for the position of a driven body or an electric motor on each axis of a machine tool; machining paths are calculated based on the acquired time-series data for the position of the driven body or electric motor on each axis; based on the calculation result for the machining paths, a height reference plane is set for each machining path; the heights from the reference planes of adjacent machining paths are compared; and the locations on the machining paths in which height differences occur that are greater than or equal to a set threshold value are displayed.

Abstract: This display device comprises a determination unit and a display unit 18. The determination unit monitors the trajectory difference between an actual trajectory and a trajectory in a machining program for a spindle, and: determines, with regard to a site at which the trajectory difference is small and the actual speed of the spindle is small relative to the maximum value setting for a command speed, whether accuracy can be maintained even if the command speed is increased; and/or determines, with regard to a site at which the trajectory difference is small and the actual acceleration of the spindle is small relative to the maximum value setting for a command acceleration, whether accuracy can be maintained even if the command acceleration is increased. The display unit 18 displays the site in a highlighted manner.

Abstract: The objective of the present invention is to display a correspondence relationship between a specific location in a machining program and specific position in a machining trajectory in such a way as to be immediately understandable, in a display device capable of simultaneously displaying the machining program and the machining trajectory. Acquired position data of a tool, and a character string from a machining program are saved in association with one another, a part of interest of a displayed tool machining trajectory is selected, and a program block comprising a character string from the machining program associated with the selected part of the machining trajectory is selected and is displayed on the displayed machining program, thereby making the relationship between the operation of the tool and the machining program more readily understandable.
