It is necessary to shear the end face to adjust the width dimension. Therefore, for example, an edge of a thick steel plate is cut using an edge mirror that cuts an end face of a workpiece with a rotating cutter. For example, Japanese Patent Application Laid-Open No. 60-99511 discloses that, when cutting with an edge mirror, as shown in FIG. 3, a cylinder tilted in the feed direction while the rotating shaft 14 is kept parallel to the end face of the workpiece, for example, the steel plate 10. It is disclosed that the end face of the steel plate 10 is cut by the cutter 12 having a shape of a circle. In the figure, 16 is
The cutting edge θ of the cutter 12 is an angle formed between the rotating shaft 14 and the steel plate 10. According to such an inclined mirror type edge mirror, great effects such as an increase in cutting speed and a prolonged tool life can be obtained. However, in this inclined cylindrical type edge mirror, the cutting edge 16 moves, for example, from top to bottom while the steel plate 10
Since the end face is cut, a blade length lt corresponding to the cutting allowance t is required as shown in FIGS. 4 (A) and 4 (B). That is, when the cutting allowance t increases to t 'as shown in FIG. 4A, the cutting start point A moves to the upstream side of the workpiece 10 and A'
Points. Therefore, at this time, the blade length required for the cutting allowance t '
l t ′ has a longer blade length than the l t . In FIG. 4, TH
Is the plate thickness of the workpiece 10, B is the cutting end point, and l TH is the blade length required to cut the plate thickness TH. Accordance connexion, a total cutting edge length as l TH + l t, determine the required length of cut and blade length when determining the necessary cutting length, it is necessary to operate so as not to exceed the cutting margin t corresponding to l t , This cut allowance t
Is the maximum cutting allowance t max that is allowable in operation. A specific cutter position control method is described in, for example,
An edge cutting apparatus disclosed in U.S. Pat. No. 511 and capable of coping with meandering of a workpiece is disclosed, for example, in Japanese Patent Application Laid-Open No. 60-238213. In any case, for example, as shown in FIG.
The 10 cutting conditions such as cutting allowance is gradually increased with the progress of, as shown in FIG. 6, for example, based on the cutting end point B, most cherish cutting margin t B on edge length constraints at that time When cutting to fit Komidai t max, the cutting start point a, will be the requesting most important Komidai t max greater cutting allowance than t a (> t B), the blade length insufficient. In FIG.
10A is, for example, a black scale surface as rolled. As a result, the state of the cut surface becomes defective, or the workpiece 10 is pressed down at the lowermost portion of the blade, causing troubles such as the workpiece 10 being rolled under the blade. This is, as shown in FIG. 7, a center position control (Center Position Control) for controlling the plate width after cutting (that is, the cutting width) based on the center line 10C of the steel plate 10 so as to be constant.
l, CPC), and as shown in FIG. 8, any of edge position control (Edge Position Control, EPC) for controlling the cutting margin (that is, the cutting margin) based on the edge shape of the steel sheet 10 to be constant. Is the same. That is, in any method, when the cutting allowance is increasing, the cutting end point B,
That also be controlled by calculating the cutting margin t B at the center of Katsuta 12, the cutting start point A, becomes its value over (t A>
t B ), the cut will be made at the part where the blade length is insufficient. Conversely, as shown in FIG. 9, in the case of cutting in which the cutting allowance is reduced, the amount of cutting at the center position of the cutter 12 is the largest, so the center position of the cutter 12, that is, the cutting end point B It is necessary to calculate and control the cutting allowance t B (> t A ). At this time, the cutting allowance t A at the cutting start point A is increased to the maximum cutting allowance t ma
When the EPC control is performed as x, the width between the centers of the cutters 12 becomes the width of the steel plate after cutting, so that the width of the plate after cutting becomes narrow. The above-mentioned problem is caused not only when the set value of the cutting allowance is increased or decreased due to a change in the sheet width, but also as shown in FIG. 10, the steel sheet 10 is skewed and parallel to the line center line. It also occurs when progressing.

If the cutting depth of the point exceeds the maximum cutting margin, edge position control with the maximum cutting margin as an upper limit is performed so that the cutting margin of the cutting end point is equal to or less than the maximum cutting margin. Or if cutting is stopped and the cutting margin at the cutting start point exceeds the maximum cutting margin, the cutting margin at the cutting start point is set to be equal to or less than the maximum cutting margin. If edge position control is performed with the important margin set as the upper limit or cutting is stopped, and both the cutting margin at the cutting start point and the cutting end point exceed the maximum cutting margin, the larger cutting margin is set. Perform edge position control with the maximum cutting margin as the upper limit, or cut the cutting margin so that the cutting margin is equal to or less than the maximum cutting margin. So as to stop, in which to achieve the above object.

下部の下への巻き込み等を防止することができる。In the present invention, when controlling the inclined mirror type edge mirror, the cutting allowances t A and t B are calculated at both the cutting start point A and the cutting end point B, and both of them are the maximum cutting on the blade length constraint. It is controlled not to exceed t max. Specifically, as shown in FIG. 1, when the cutting margins t A and t B of the cutting start point A and the cutting end point B are both equal to or less than the maximum cutting margin t max, for example, based on the cutting margin t B of the cutting end point to continue the CPC control or EPC control (step 116). In addition, in the case cut bill t A of the cutting start point is equal to or less than the most important Komidai t max, which cut bill t B of the cutting end point exceeds the most important Komidai t max is, the cutting end point as cutting allowance t B is equal to or less than the outermost importance Komidai t max of cutting the EPC control of up to t max in a range of means pursuant, cutting cost does not exceed the maximum importance Komidai t max. Alternatively, cutting may be stopped (step 11).

Calculate the depth of cut for each point, and if any of them is less than or equal to the maximum depth of cut on the blade length constraint, the plate width after cutting is assumed to be constant based on either depth of cut. Central position control to control the cutting edge, or edge position control to control the cutting margin to be constant.If the cutting margin at the cutting end point exceeds the maximum cutting margin, the cutting is performed. Perform edge position control with the maximum cutting margin as an upper limit, or stop cutting, so that the cutting margin at the end point is equal to or less than the maximum cutting margin, or set the cutting margin at the cutting start point to the maximum cutting margin. If the cutting margin is exceeded, the cutting margin at the cutting start point will be less than the maximum cutting margin In this way, when performing the edge position control with the maximum cutting margin as an upper limit or cutting is stopped, when the cutting margin of the cutting start point and the cutting end point both exceed the maximum cutting margin. An edge mirror control method, wherein edge position control is performed with the maximum cut margin as an upper limit or cutting is stopped so that the larger cut margin is equal to or less than the maximum cut margin.
