ｍであったものが。As electronic devices become lighter and smaller, the circuit boards used therein are becoming more dense. Naturally, in this high-density circuit board, the circuit elements to be mounted are also downsized, and various holes formed on the printed circuit board, such as holes for mounting them, are also inevitably downsized. That is, conventional diameter Q, 8m

出するものなど、各種のものがある。Normally, this printed circuit board drilling is performed by an automatic drilling machine using a drill, and if a breakage of the drill is detected, the drilling process is immediately stopped. Conventionally, as a detector for detecting breakage of a drill, there are (a) one that detects the change in cutting torque due to the breakage; (c) A method that irradiates the drill with the light beam emitted from the projecting head through an optical fiber, and detects the breakage of the drill optically from the amount of light that enters the light receiving head. , there are various types.
しかし、これら従来の検出器は、直径０．８鮎のドリル
の折損を検出するのが限界であって、それ以下のドリル
の折損を確実に検出することができない。However, these conventional detectors are limited to detecting a breakage of a drill with a diameter of 0.8 mm, and cannot reliably detect a breakage of a drill with a diameter smaller than that.
すなわち、切削トルクの変化や届センサから出力される
信号から検出するものは、ドリルの直径が小さくなると

射された光が受光ヘッドに入射し、ドリルの折損が検出
できなくなる。In other words, as the diameter of the drill becomes smaller, the cutting torque and AE signal themselves become smaller and the S/N ratio decreases, making it impossible to detect what is detected from changes in cutting torque and signals output from the delivery sensor. . What is detected optically is that the light emitted from the tip of the optical fiber is diffused at an angle of about 60 degrees (7 Light enters the light receiving head, making it impossible to detect a broken drill.
本発明は、上記事情を勘案してなされたもので。 The present invention has been made in consideration of the above circumstances.

加熱されている。したがって。No drilling of the workpiece (2) is performed. Therefore, the temperature of the drill (1) does not rise. Therefore, as shown in FIG. 4(A), the temperature T indicated by the electric signal ST becomes lower than the set value T. As a result, the abnormality signal 8I is outputted from the first comparison circuit 09 to the OR circuit (17), and the abnormality signal SK is outputted from the OR circuit α to the NC unit 1. Then, the NC unit u9 outputs a control signal to interrupt the drilling operation to replace the drill at the drilling machine (marked 1).On the other hand, as shown in Fig. 5, the drill (1) has been used for a long time and If it is worn out, it will be heated to a higher temperature immediately after drilling is completed than if it is not worn out.

続する。As shown in FIG. 4(B), the temperature T indicated by the electric signal ST becomes higher than the set value T. As a result, the abnormality signal SJ is output from the second comparison circuit (Ifi) to the OR circuit α, and the abnormality signal SK is output from the OR circuit θη.
(11), and the drilling operation is interrupted in the same way as before. However, the drill (1) is in a normal state, and therefore the temperature at the tip of the drill (1) immediately after drilling is as shown in Figure 4 (C).
), T<T<T. As a result, the abnormal signal SK is transmitted from the zero circuit αη to the NC section (11
There is no output and the drilling operation continues according to the cutting program.
