As shown in Fig. 10, the display device 1A of a machine tool according to the third embodiment is different from the display device 1 of a machine tool according to the first embodiment in that it includes a condition range acquisition unit 14, and other configurations are the same as those of the first embodiment.
  • the range of the machining conditions and the swing conditions can be specified.
  • the condition range acquisition unit 14 acquires the range of processing conditions and swing conditions from an input unit such as a keyboard or a touch display, or an input means (not shown) such as an external computer.
  • the range of processing conditions is, for example, the range of feed amount [mm] and the range of cutting edge [mm].
  • the operator can specify the feed amount [mm] range from 0 to 1.0 or a different range through input means (not shown), or specify the cutting edge [mm] range from 0 to 1.0 or a different range. You can also specify.
  • the range of the rocking conditions is, for example, the range of the rocking frequency magnification I [times] or the range of the rocking amplitude magnification K [times].
  • the operator may specify the range of the oscillation frequency multiplier I [times] to 0 to 16.0 or a different range, or specify the range of the oscillation amplitude multiplier K [times] from 0 to 16.0 through an input means (not shown). It can be specified as 0 or a range different from that.
  • the machine tool display device 1a of the third embodiment further includes a condition range acquisition section 14 that acquires the range of machining conditions and swing conditions that can be input, and the condition input section 11
  • the acquisition unit 14 receives input of machining conditions and swing conditions based on the input range acquired. This results in a prespecified input range, making it possible to realize an interface that is easier for operators to use depending on the situation.
  • the configuration of the machining state calculation unit 12 of the above embodiment can be changed as appropriate depending on the circumstances, such as omitting some functions or adding other functions.
  • the configuration of the third embodiment may be combined with the configuration of the second embodiment.
  • the display unit 13 may be configured to display items different from those described in the above embodiments.
