- By making relative displacements in the Y plane, the same tool electrode can be used to perform multiple steps of rough machining, semi-finishing, semi-finishing, and fine finishing machining, as well as electrical discharge machining. It is known to remove the resulting cutting powder from the workpiece and modified substances of the insulation machining fluid thermally decomposed by the high-temperature arc during the discharge from the discharge machining gap via the machining fluid. In addition, in order to perform machining on a workpiece that is either larger or smaller than the tool electrode, the above-mentioned relative displacement movement in the I try to give. These relative displacement distances are only about 50 to 500 μm, which is a minute distance for so-called finishing allowance, because the purpose is to perform rough machining to finish machining without changing the electrode. Recently, N/C devices have been used to provide the above trajectory between the electrode and the workpiece, and control the table on which the workpiece is placed or the head to which the electrode is attached in the XY plane. The above processing is performed automatically. In an N/C device, a desired trajectory is first programmed onto a paper tape, etc., but checking whether this program really matches the desired trajectory can be done by, for example, moving the table without machining in idle operation. Since the amount of movement was small as described above, it was difficult to visually confirm this. Also, once processing begins,
It was nearly impossible to check the state of the trajectory as the machining progressed, and problems arose when we found out how the machining process had been completed only after the machining process had finished.

管１３上で明確に確認できる。 An embodiment of the present invention will be described below with reference to the drawings. In the figure, a tool electrode 1 and a workpiece 2 first undergo machining by receiving machining energy from a machining power source 3 while performing relative motion in the Z axis, which is the main machining direction. Next, machining is performed by applying a relative displacement between the tool electrode 1 and the workpiece 2 in the XY plane. Relative displacement in the X-Y plane is determined by moving the table 4 on which the workpiece 2 is placed, for example, to the drive motors 7 and 8 according to a trajectory programmed in advance on the paper tape 6 or the like by the N/C device 5.
It is done by making it move. This relative displacement is extracted as a two-phase phase output by optical encoder detectors 9X and 9Y attached to the X-axis and Y-axis, respectively, and this is output to the detectors 10X and 9Y.
It is converted into positive direction and negative direction pulse output via 10Y. The above pulses are each reversible counter 1
1X and 11Y, and the current position is digitally stored from the counter. These current values are converted into analog voltage values by the D/A converters 12X and 12Y, and amplified by the vertical amplifier circuit 14 and horizontal amplifier 15 of the cathode ray tube 13.
It is displayed on the cathode ray tube 13 as X and Y coordinates.
Since the distance from the origin of relative displacement between tool electrode 1 and workpiece 2 to the maximum point of relative displacement is usually about 500 μm, the required number of bits for reversible counters 11X, 11Y and D/A converters 12X, 12Y is 10. It would be nice if there were bits, but if the origin of the relative displacement is biased, the reversible counters 11X and 11Y may overflow, or the cathode ray tube 13 may overflow.
Since I don't know where the origin is above, I use reversible counter 1.
Reset terminals 16X and 16Y of 1X and 11Y are provided, and a reset switch 17 is used to reset at the origin of the tool electrode 1 and workpiece 2, so that the center of the cathode ray tube 13 always coincides with the origin. As a result, the XY coordinates of the relative displacement can be clearly confirmed on the cathode ray tube 13.

After machining is performed by applying a minute displacement of 100 μm, when moving the tool electrode 1 to another location and performing machining by applying a minute displacement at that location, the reset terminals 16X and 16Y are connected to the N/C device 5. If the counter is reset when a minute displacement is applied, the status of minute displacement can always be checked on the cathode ray tube 13 even if the stroke of the table 4 is large.

という利点がある。 As described above, according to the present invention, not only can minute relative displacements between the electrode and the workpiece be confirmed on the display device with the origin of displacement always centered, but also the difference between the command value of the displacement trajectory and the actual movement. This has the advantage of being able to be visually confirmed.
