<p>PURPOSE:To reduce the time and labor required for correction of data by deciding the working method based on the comparison carried out between the sum of the evaluation values decided by each evaluation function and the prescribed threshold value. CONSTITUTION:A processor 1 obtains the evaluation value U1 set to the tilt A of a graphic element e2, the evaluation value U2 to the X axis length L of the element e2, and the evaluation value U3 to the Z axis cutting margin D of a rectangular area respectively. Then the weight W1 (i=1,2,3) is read out of parameter storage part 9 to each decided item and then multiplied by those values U1 - U3. Then the sum M of these multiplied values U1 - U3 is calculated. The threshold value T is read out of the part 9 and compared with the sum M. If the sum M is larger than the value T, the element e2 is defined as a subject of the end face machining. Then the element e2 is defined as a subject of the lengthwise machining if the sum M is smaller than the value T. Thus the time and the labor required for correction of data can be reduced.</p> |
