Classification: CPC G  B | IPC B  G

Claim 0:
1. A processing method for processing a workpiece into a desired shape by a tool, comprising:
incorporating an arithmetic expression for correcting a position of the tool into an Numerical Control (NC) program, the NC program being configured to correct the position of the tool by directly inserting coded numerical instructions into the tool;
calculating a processing path along which the tool transfers according to the NC program;
calculating a cutting transfer distance for cutting the workpiece by each part of the tool from the processing path;
calculating a wear amount and a deflection amount of each part of the tool from the cutting transfer distance;
correcting the NC program by the wear amount and the deflection amount in addition to a contour error of the tool; and
performing processing by the corrected NC program.
