PURPOSE:To generate a highly accurate working program even with a rough teaching action by minimizing the sum total of square of the error of each of error vector components (x), (y) and (z) against each pair of variables of a conversion matrix and then calculating the variable value by the minimum square method. CONSTITUTION:The sum total of square of the error of each of error vector components (x), (y) and (z) against each pair of variables of a conversion matrix. Then the variable value is calculated by the minimum square method and used as the most approximate value of the conversion matrix. Thus the minimum number of teaching points is limited to three and the error of the conversion matrix is reduced in proportion to the number of teaching points. As a result, the coordinate converting accuracy is improved and a highly accurate working program is generated.
