  • the numerical control device 2 may include a pattern updating unit that updates any axis configuration pattern included in the plurality of axis configuration patterns stored in the axis configuration storage unit 24.
  • the pattern update unit is realized, for example, by the hardware processor 201 performing arithmetic processing using the system program stored in the ROM 203 and various data stored in the nonvolatile memory 205.
  • FIG. 12 is a diagram showing an example of the functions of the numerical control device 2 equipped with a pattern update section.
  • the numerical control device 2 shown in FIG. 12 differs from the numerical control device 2 shown in FIG. 8 in that it includes a pattern update section 29. Therefore, here, the pattern update unit 29 and the functions related thereto will be explained, and the explanation of the same functions as those explained using FIG. 8 will be omitted.
  • the pattern update unit 29 updates any axis configuration pattern included in the plurality of axis configuration patterns stored in the axis configuration storage unit 24.
  • the pattern update unit 29 updates one of the axis configuration patterns stored in the axis configuration storage unit 24, for example, in response to the command reception unit 27 receiving an update command to update the axis configuration pattern.
  • FIG. 13 is a diagram showing an example of a machining program including an update command.
  • the update command shown in FIG. 13 adds "Z2" to the first system of the first axis configuration pattern shown in FIG. 11, deletes "Z3", and deletes "Z2" of the second system. This is an update command to add "Z3" to the third system.
  • FIG. 14 is a diagram showing the changed first axis configuration pattern.
  • the update command may be specified in other than the machining program.
  • the update command may be input from the operation panel.
  • a predetermined signal is output from the numerical control device 2
  • the numerical control device 2 may store a plurality of tables for setting identification numbers to system variables. For example, the numerical control device 2 may read any one of the plurality of tables based on an operator's operation. As a result, the identification number set in the table is set in the system variable. As a result, multiple axis configuration patterns can be updated with a single operation.
