- a machining time prediction unit configured to predict, for each block of the machining program, a machining time based on the command of the block;
- a look-ahead block number calculation unit configured to calculate, for each block of the machining program, the number of blocks prefetched while the block is being executed;
- an editable time calculation unit configured to calculate an editable time for the block of the machining program;
- a program editing unit configured to display the machining program to accept a user's editing and write the result of the editing into a machining program used for the control;
- and
- an editable time display unit configured to display an editable time for a block being edited,
- wherein the program editing unit makes editable only those of a plurality of blocks in the machining program which have the editable time left remaining and locally writes only edited portions into the machining program used for the control.
