Claims

[Scope of utility model registration request]

First-in is a numerical control device with a reverse function that interrupts machining while the machining program is running in the forward direction, moves in the reverse direction to a predetermined position in the machining program, and then continues machining in the forward direction again by a predetermined operation.・First in
Last out (hereinafter referred to as FILO) is equipped with a memory means, and a modal command that is commanded in the machining program and maintains the control state until another command of the same group is commanded, is stored in the group to which the modal command belongs during forward direction control. FIL assigned to
O memory means stores the modal command read from the machining program during reverse direction control into the FILO assigned to the group to which the modal command belongs.
A numerical control device characterized in that a modal state within the numerical control device is restored by reading from a memory means and further reading and executing a modal command stored in the FILO memory means when restoring forward direction control.
