Since the movement is controlled in the axial direction and the rafter notch q2 is indented only on the upper surface of the horizontal member O, there is no need to move the upper cutter 62 in the X-axis direction.

However, when cutting the stud notches ql and rafter notches q2, the horizontal member O is processed upside down, and the lower surface of the workpiece W becomes the upper surface of the horizontal member O.

Next, the positioning mechanism for positioning the workpiece W by contacting the front end cut surface of the workpiece W will be explained.

Drilling can be performed by moving Q and R in the axial direction.

Next, the operation and effects of the embodiment having the above configuration will be explained.

Now, when cutting the horizontal member O, first place the workpiece W on the feed conveyor 70, transfer it to the left until the front end surface of the workpiece W comes into contact with the first stopper 7, After cutting near the front end of the workpiece W and scraping the reference end face 01 of the horizontal member O, the first flange 7 is retracted from the transfer path F. On the other hand, while cutting the second stopper 63 at each position to be processed into the workpiece W, cutting is first performed at the shortest position from the reference end surface 01, and then cutting is repeated at positions successively farther away from the reference end surface 01. In order to do this, the workpiece W is moved to the left until it comes into contact with the second stopper 63 while waiting in advance at the rightmost position of the movement stroke, and at this position, each vise 67 is activated to move the workpiece W. After clamping, a first cutting process is performed at a predetermined processing station (first processing station S1 in this example). moreover,
When the first cutting process is completed, the workpiece W is unclamped and moved to the left for the next cutting process, and then moved to the left to define the next cutting position of the workpiece W and placed in a waiting position. It comes into contact with the second stopper 63 again, is clamped by the vise 67, and the cutting process on the workpiece W is repeated at a predetermined processing station.

Then, when all the cutting processes are completed by repeating the above series of operations, the workpiece W is carried out from the delivery conveyor 71,
The second stopper 63 returns to the right moving end and waits in order to define the first cutting position for the workpiece to be subsequently machined.

Therefore, all the various forms of cutting required for the horizontal member O can be performed within a single machine, which significantly reduces machine installation space, required number of workers, workpiece transfer distance, etc. Controlling the movement of the two-stopper 63 eliminates the need for staking work, and has the effect of improving processing accuracy.

Further, the second stopper 63, each machining unit, etc. can be controlled by a computer to fully automate the cutting process.

In the above cutting process, in this example, the blade center line C1
, DI and the distance between the blade center line D1゜El are set to multiples of 1/2 of the basic column spacing 2 x P1.
When the second stopper 63 is set at a position of 11 + 3
Since it is sufficient to cut the mortise hole 11 at the position LE) and the mortise hole 11 at the position 11+P1 (LD), it is necessary to cut the large dovetail 11), the stud notch ql, and the mortise hole 11 without moving the second stopper 63. can be performed simultaneously in each processing unit C, D, and E. In other words, in general, in horizontal members for wooden constructions, a mortise hole i is bored at a position 2XP1 to the left of the dovetail 11) h, and a stud hole q/ is bored at a position P1 to the left of the mortise hole i. A combination of machining positions for fi-cutting is frequently used, and this has the effect of reducing the required number of machining operations for a horizontal member having this combination, thereby increasing the efficiency of the cutting work.

Also, in Fig. 6, 3xP2 = 2XP1, that is, P 2
= 2/3p i, but generally P1=P, -
Y) 2 is often the case, and in this case, joist carving J1 stud missing q
Since the positions of 1 and 1 coincide, cutting can be performed at more positions at the same time, and the number of machining operations, required machining time, and number of workpiece transfers can be significantly reduced, making the machining process more efficient and rational. can.
