加工物に工作機械の主軸に取付けたタップにより自動的
にねじ立てをすることは公知である。It is known to automatically tap a workpiece into a workpiece using a tap attached to the main shaft of a machine tool.
従来はタップを早送りにより加工物の加工開始位置まで

より待機位置に戻る工程を行う。Conventionally, the tap is fed rapidly to the machining start position of the workpiece, the cutting feed is performed at a rotational speed suitable for the workpiece's upright position, and after cutting is completed, the tap is reversed and the return process is performed at the same speed as the cutting feed. conduct. After detaching the workpiece, a process of returning to the standby position is performed by high-speed rapid forwarding.

るという問題があった。Conventionally, the feed speed when the tap is fed into the workpiece for cutting and the reverse return process when removing the tap after setting it up are the same speed, so it is difficult to remove the tap. The problem was that it took time.

徴とする自動タッピング方法により達成した。. The present invention solves the above-mentioned problem by replacing the return process of reversing the tap and pulling it out after tapping is completed, by performing the return feed of the tap at a high speed that allows relative movement without damaging the internal thread after the tap is created. This was achieved by an automatic tapping method characterized by simultaneously rotating at a speed determined by the return feed speed and the diameter and pitch of the female thread.
切削送りの際はタップは加工物に対する切削作業をする
のでタップの送り速度及び回転速度は限定を受ける。し
かじねじ立後はタップは加工物に対しては切削作業を行
わないので切削されたねじに沿って移動できればよい。During cutting feed, the tap performs cutting work on the workpiece, so the feed rate and rotational speed of the tap are limited. However, after tapping the thread, the tap does not perform any cutting work on the workpiece, so it only needs to be able to move along the cut thread.
又移動の際の抵抗も非常に小さい。したがってねし戻し
送り速度と回転速度がマツチできる限りにおいて高速度
で、例えば切削送りの２倍〜３倍の速度で送ることが可
能になる。Also, the resistance during movement is very small. Therefore, as long as the unwinding feed speed and rotational speed can be matched, it is possible to feed at a high speed, for example, twice to three times the cutting feed speed.

That is, from the standby position Wa to the position just before the start of the hoisting operation, an approach process by rapid forwarding is performed as the first process. Since there is no resistance when the tap moves, high-speed feeding is possible.

れることができる。Once in position, the feed rate is reduced to a speed convenient for cutting. This speed is determined by the material of the workpiece, the tap pitch, the diameter, etc. The rotational speed of the tap 3 is also selected to be convenient for cutting. In this way, cutting feed is performed as the second step from position zb to the finishing position C of the threading process, that is, by an amount determined by the effective thread length of the female thread. In the first step, the tap 3 can be rotated at the same speed as selected for the second step.

The main shaft motor 7 is reversed by the control signal, and at the same time, the return feed speed and rotation speed are controlled to be high. As a result, from position Wc to position b' where the tap 3 leaves the workpiece 1, as a third step, the tap 3 is returned at a higher speed than the cutting feed, for example, twice to three times as fast, and the extraction step is performed.
