The measured length L of the steel W is taken into the comparison processing device 85. This comparison processing device 85
Since the punching setting position LHn and the cutting setting position LCn stored in the punching setting position / memory 81 and the cutting setting position / memory 83 are already taken in, the measured length L and the punching setting position are set. The LHn and the disconnection setting position LCn are compared.

In this comparison process, when the measured length L matches the drilling setting position LHn (L = LHn), the drill heads 41R, 41L, 41U are actuated to drill holes at predetermined positions from both sides. When the measured length L matches the cutting setting position LCn (L = LCn), the circular saw machine 4

In addition, since the punching device 5 and the cutting device 7 can be automatically performed in a series of steps, the setup work is easier than before, and the installation area can be saved. Further, since the H-shaped steel W is fed and positioned simultaneously in the drilling and the cutting, the machining can be performed accurately and the machining accuracy can be improved.

FIG. 4 shows an example in which a square pipe W as a workpiece is subjected to drilling and cutting.
The specific structure and creation are almost the same as those shown in FIG.

The present invention is not limited to the above-described embodiments, but can be implemented in other modes by making appropriate changes. In this embodiment, the H-shaped steel and the square pipe have been described as an example of the work, but a round pipe and other shaped steels are also applicable. Further, although an example of measuring the entire length by using an encoder as the length measuring device has been described, the length may be measured by step feed or various combinations may be used. A circular saw machine has been described as the cutting device, but a die cutting by a press or the like may be used. Further, although a drill machine has been described as an example of the drilling device, the H-shaped steel W may be drilled by a laser processing machine or a punch press.

[0033]

As will be understood from the above description of the embodiments, according to the present invention, since the structure is as described in the claims, the hole is drilled at the desired position of the work. However, the cutting process can be performed automatically and accurately. Since the punching process and the cutting process can be performed in a series of steps, the setup work is easier than the conventional process and the space can be saved.
Further, since the work can be fed and positioned at one time, the working accuracy can be improved.
