Has a concave portion 2, and a small round 3 is formed around the concave portion 2. After the entire round shape is processed, a small round 3 is formed by a tool such as a ball end mill cutter having a smaller radius than the small round 3. It is necessary to carry out detail copying within the range including.
【０００５】図５は、この細部倣い加工における従来方
法の一例として、加工範囲４を対角線で長方形に設定し
た場合であり、加工方向はＸ軸及びＹ軸方向のパラレル
加工となっている。FIG. 5 shows an example of a conventional method in the detail copying, in which the processing range 4 is set to be a rectangle diagonally, and the processing direction is parallel processing in the X-axis and Y-axis directions.
【０００６】図６は、同様の例であって対角指定をしな

細かく指定する。このときの加工方向もＸ軸及びＹ軸方
向のパラレル加工となる。FIG. 6 shows a similar example in which the diagonal designation is not performed, and the operator finely designates the processing range 5 to 8 as an example. The processing direction at this time is also parallel processing in the X-axis and Y-axis directions.

り、細部倣い加工における工数増大の原因になってい
る。In the case of specifying a diagonal line as shown in FIG. 5, a large amount of useless portions 9 are included in the processing range, so that the uselessness of the processing is increased. In addition, the processing directions are limited to the X-axis and Y-axis directions, and the two-direction processing is indispensable for maintaining the quality, and the processing method is also limited to the parallel processing. Therefore, the processing time becomes extremely long, which causes an increase in man-hours in detail copying.
【０００８】一方、図６に示すような非対角線指定の場

設定に著るしく長い時間が必要になり、この点でやはり
細部倣い加工における工数増大の原因になっている。On the other hand, in the case of specifying a non-diagonal line as shown in FIG. 6, a waste of the processing range can be reduced, but a considerably long time is required for setting the processing range. This is causing an increase in man-hours.
【０００９】また、加工方向はやはりＸ軸及びＹ軸方向
