Title: NUMERICAL CONTROL APPARATUS
Abstract:
A numerical control apparatus (100) is provided with a control unit which sequentially executes blocks of a machining program (1) in reverse order, wherein the control unit displays, on a display unit (101), the machining program (1) and the block thereof currently being executed, and wherein, after the execution of the executed machining block has been interrupted, if a destination block, which is a machining block to be subsequently executed, is specified by performing an operation on the part of the display unit (101) where the machining program (1) is being displayed, and if a path is traced on the part of the display unit (101) where the interrupted block and the destination block of the machining program (1) are being displayed, then the control unit performs either a normal-order control, in which a plurality of blocks described in the machining program (1) are executed in the same order as when the machining program (1) is used to perform an automatic operation, or a reverse-order control, in which the plurality of blocks are executed in the reverse order from the order in which these blocks are executed in the normal-order control, depending on the tracing speed and the length and direction of the traced path.
