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.
Claims1
A numerical controlling method for controlling a mirror image, for use in a machine tool, comprising the steps of:
- (a) reading an instruction block from a numerical controlling program;
- (b) determining whether a predetermined mirror image code is in said read instruction block;
- (c) when said mirror image code is found in said step (b), determining the coordinates of a target location according to said mirror image code;
- (d) adding predetermined interpolation data to the coordinates of said target location determined in said step (c) to produce the same cutting direction as an original cutting direction;
- (e) moving a tool according to said coordinates of said target location interpolated in said step (d);
- and
- (f) moving said tool in said original cutting direction as instructed in said numerical controlling program, when no image mirror code is found in said step (b) .
