<P>PROBLEM TO BE SOLVED: To provide a grinding machine which obtains moving route data of a grinding wheel with respect to a slope to be ground of a workpiece, the slope having an inclined angle changed in a three-dimensional curved surface manner, based on distal end shape data of the grinding wheel and working shape data of the workpiece, and which enables an NC program to be easily generated. <P>SOLUTION: Three-dimensional coordinate data of a distal end shape of the grinding wheel are calculated by a distal end shape three-dimensional coordinate data conversion part 51 provided in a CPU 42. Working shape three-dimensional coordinate data of the workpiece are calculated by a working shape tree-dimensional coordinate data conversion part 52. Moving route data of the grinding wheel with respect to the slope to be ground of the workpiece, the slope having an inclined angle changed in a three-dimensional curved surface manner, are calculated by a moving route data calculation part 53 based on both of the coordinate data. NC commandment data are formed by an NC commandment data calculation part 54 based on the moving route data. <P>COPYRIGHT: (C)2012,JPO&INPIT |
