。As is well known, a wire-cut electric discharge machine is a wire electrode (hereinafter simply referred to as a wire) that is stretched between an upper guide and a lower guide, and an electrical discharge is generated between the wire and the workpiece to machine the workpiece. The work is placed on the table.
It is moved in the X and Y directions according to commands from the numerical control device according to the machining shape. In this case, if the wire is stretched in the vertical direction with respect to the table (work) K, the machining shape of the upper and lower surfaces of the workpiece will be the same, and the master guide will be aligned in the X and Y directions (U axis, V axis). The shaft is configured to be able to move KM, for example, in a direction KM perpendicular to the direction of movement of the workpiece.
If the upper guide is displaced to tilt the wire relative to the workpiece, the machining shapes of the upper and lower surfaces of the workpiece will not be the same, and so-called taper machining, in which the wire machining surface is inclined, will be performed.

なえばテーパ加工ができる。Figure 1 shows a schematic diagram of a 4-axis controlled wire-cut electrical discharge machine.The workpiece WK is moved in the X and Y directions by motors MX and MY, respectively, on an X-Y table T.
It is fixed on B. On the other hand, the wire WR is the reel RL
, and is wound onto the reel RL while being stretched between the lower guide DG and the upper guide UG, and a voltage is applied by a contact electrode (not shown) so that an electric discharge occurs between the workpiece WK and the workpiece WK. In addition, the upper guide UG
is provided with a column CMK movable in the X and Y directions for motors MU and MY, respectively.

In such a wire-cut electric discharge machine, taper machining can be performed by displacing the upper guide UG in the X and Y directions and tilting the wire WR with respect to the workpiece WK.

A wire WR is stretched between G and the lower guide DG so as to be inclined at a predetermined angle with respect to the workpiece WK. Now, the lower surface PL of the work WK is set to a program shape (the upper surface QU of the work WK may be set to a program shape), and the taper angle α,

一点鎖線はそれぞれ上ガイドUG。By controlling the movement of the upper guide UG on which the wire WR is stretched so that d is constant, taper processing with a taper angle α as shown in FIG. 5 can be performed. In addition, in the figure, the dotted line and the dashed-dotted line are the upper guide UG, respectively.

が行われる。This is the passage of the lower guide DG. In addition, when performing taper machining, as mentioned above, the program path on the lower or upper surface of the workpiece, the feeding speed on the wrinkle program path, the taper angle α, the distances H, h, etc. are generally commanded. The instructions are processed.

加工機においては、しぼシ部NSU、NSDの中心部(
黒丸部)テーパ角度変更の支点とみなして上ガイドUG
の相対移動量を決定して運動制御する。By the way, when performing taper machining with a wire-cut electric discharge machine, a circular hole die is usually used. FIG. 4 is an explanatory cross-sectional view of the circular hole die used as an upper guide UG and a lower guide DG. In the figure, CH is a circular hole, NSU is a wrinkled portion of the upper guide UG, and NSD is a wrinkled portion of the lower guide DG, all of which have an acute angle or a small radius. Well then, huh?
In an electrical discharge machine that uses circular hole dies as the upper and lower guides, the central part of the wrinkled parts NSU and NSD (
Black circle) Upper guide UG is considered as the fulcrum for changing the taper angle.
The motion is controlled by determining the amount of relative movement.

対移動量を計算し、該移動量に基いて上ガイドの移動制
御を行なっている。That is, the angle between the straight line connecting the two fulcrums and the workpiece is the taper angle α, and the vertical distance between the two fulcrums is the distance from the fulcrum of the H1 lower guide DG to the bottom surface of the workpiece is h, and the relative movement amount of the upper guide UG is The movement of the upper guide is controlled based on the calculated movement amount.

第4図の破線に示すようになり、正しく角度αを示さな
くなる。又、ワイヤが急激に折れ曲るためワイヤ位置が
、ワイヤ送行中に変動し高精度の加工ができない。By the way, if the buried parts NSU and NSD of the circular hole die are machined to have an acute angle or a minute B, since the wire actually has a predetermined thickness and has a certain bending rigidity, When the taper angle α increases, the locus of the center of the wire becomes as shown by the broken line in FIG. 4, and the angle α is no longer indicated correctly. In addition, since the wire bends suddenly, the wire position fluctuates during wire feeding, making it impossible to perform high-precision machining.

目的とする。From the above, the present invention provides a guide for taper machining of an electric discharge machine, which can set the taper angle to a command angle, and can perform highly accurate taper machining without changing the position of the wire while feeding the wire. The purpose is to provide a processing method.
以下、本発明の実施例を図面に従りて詳細に説明する。Embodiments of the present invention will be described in detail below with reference to the drawings.

の乱れはなくなる。FIG. 5 is a cross-sectional explanatory view of a guide for taper machining of an electrical discharge machine according to the present invention, and in the figure, WR is a wire, UGd is an upper guide, and DG is a lower guide. Although not shown, a workpiece is disposed between the upper guide UG and the lower guide DG. Now, each of the upper guide UG and lower guide DG has a part UGW on the side where the work is present and where the wire WR is guided.
, UGW' (upper guide), DGW, and DGW' (lower guide) are machined into circular arc shapes with a medium diameter R, and the sides UGυ and DGυ of each guide where no work is present are each formed into a circular ring shape. There is. That is, both the inlet portion of the upper guide UG and the outlet portion of the lower guide DG are formed to have an arcuate cross section (spherical shape) with a medium diameter R. Note that it is desirable that the radius be at least three times, preferably five times or more, the wire diameter. As described above, when the inlet and outlet portions of the guide are processed to have a half IIR, the problem of bending of the wire WR as in the conventional example is eliminated. In other words, the wire WR is smoothly guided inside the die and is stretched tightly, and if it becomes slack, it will not come loose.
This eliminates the disturbance of the Taber angle due to ear positional fluctuations and wire rigidity.

ある。Now, when a guide having the structure shown in FIG. 5 is used, the actual wire fulcrums shift to point A and point A', respectively. still,
Point A and point A' are both intersection points of the straight part WRn of the wire WR and the center of the tapered part WRt. When programming with Totoro, the program path, distances H, h, and taper angle α are commanded assuming that the wire fulcrums are at the 0 point and the 07 point, respectively. Therefore, during actual machining, it is necessary to correct command data or other data based on the taper angle α.
次に補正方法について第5図を参照しながら説明する。Next, the correction method will be explained with reference to FIG.

There is a method of correcting the moving distance of the guide. In other words, move the lower guide DG and move the upper guide UG to the right.
