ABSTRACT:
A numerical control method includes the steps of (a) reading an instruction block from a numerical control program; (b) if a predetermined mirror image code is in the instruction block, determining the coordinates of a target location according to the code; (c) adding predetermined interpolation data to the target location coordinates; and (d) moving a tool to the target location to produce the same cutting direction as an original cutting. Thus, uniform machining precision can always be obtained.
