PURPOSE:To separate a tool from a work the maximum distance with the highest speed in an NC machine tool by obtaining an escaping command for moving the tool in the relative moving and vertical directions from a memory means of moving command in the escaping operation of the tool. CONSTITUTION:NC data are read by a tape reader puncher 102e and stored in a data memory 102c so that a processor 102a executes a working control program by the operation of a operating board 102d. And when a tool escapes in the breakage or the like, the processor 102 reads out the moving command stored in the data memory 102c while reading out escapement amount and escapement spped to give tool escapement command to X, Y axes drive circuits XDV and YDV and drive X, Y axes motors 105, 110 so that the tool CT moves relatively in the relative moving direction and the vertical direction during working for escapement. Thus, the tool can be separated from a work in the normal direction the largest distance with the highest speed so that the work is prevented from unnecessary working.
