Abstract: An information processor performs simulation processing based on information on a workpiece and a machining program and specifies an air-cut path, which is a tool path in which the tool is not in contact with the workpiece, for each of blocks included in the machining program, based on the result of the simulation processing. Moreover, the apparatus calculates a time required for a movement in the air-cut path for each block and changes the display mode of the block on a screen based on the calculated time.

Abstract: A numerical controller controls a machine tool that measures a coordinate value of an object to be measured based on a position of a movable axis controlled by a manual operation. The numerical controller stores a plurality of pieces of history information formed by associating the coordinate value of the movable axis and an elapsed time from a reference time point when the coordinate value is acquired, analyzes timing when position adjustments of the movable axis are completed based on the stored history information, and sets the coordinate value of the movable axis at the analyzed timing.

Abstract: A numerical controller controls a spindle and/or a movable axis of a finishing machine based on a machining program. A cutting condition display device configured to display a cutting condition for the numerical controller calculates cutting conditions including a cutting speed, a feed per spindle revolution per cutting edge of a tool, and a depth of cut for each fixed time during an operation of the finishing machine, based on any or a combination of data on the spindle, the movable axis, a cutting tool, and an object to be cut, which are held by the numerical controller. The calculated cutting condition is stored for each tool and displayed in a graph.
