PCT No. PCT/JP85/00277 Sec. 371 Date Jan. 21, 1986 Sec. 102(e) Date Jan. 21, 1986 PCT Filed May 21, 1985 PCT Pub. No. WO85/05473 PCT Pub. Date Dec. 5, 1985.Numerical control apparatus for controlling a mirror image function in a machining program. When a mirror image code and a position for each coordinate axis with a mirror are set (steps S2, S4, S7), mirror image instruction executing data (FX=1, FY=1) and mirror positions (XM, YM) are set for the coordinate axis with the mirror (steps S5, S6, S8, S9). Shift instruction values (Xi, Yi) Programmed in response to the execution data and mirror positions are converted to mirror image shift instruction values (2XM-Xi, 2YM-Yi) (steps S12, S15), and the mirror image shift instruction values are output (step S16). NC machining is executed according to the mirror image shift instruction values.
