One if the previous block is an arc command or a straight line command with a radius larger than the set radius value, and the distance between the start point and end point is longer than the set value. Automatic connection is performed at the intermediate position between the start and end points of the previous block.

Since it passes through the lower guide 18, it is necessary to guide the wire 20 to the lower guide 18 without disturbing the machining fluid flow in the machining groove or the starting hole. It is.
- the wire connection position be uniform around the wire to be inserted with respect to the machining fluid flow.
- the disconnection occurs, no additional groove is formed, and the three directions around the wire are covered with the cut surface of the peak W, which is not a uniform condition.c
- the machining fluid is sprayed from the upper nozzle at this position, the machining fluid flow is disturbed, and it is difficult to penetrate the wire 20 to the lower guide 18.
- the block in which the wire breakage occurs is arc processing, and the arc radius is smaller than the set value rO, the flow of the machining fluid in the machining groove is not uniform. Disturbance makes it difficult to pass wires down to lower guide 18.
- the distance between the breaking point and the processing start point of the broken block is the set value D in the straight portion of the machining groove or in an arc whose radius is equal to or greater than the set value r0.

Then, the machining fluid flows in the wire running direction to the wire feed pipe structure 12, the guide, and the wire 25, and the machining fluid is injected from the nozzle 7 a of the upper guide 7. Then, the wire 20 is further fed out by the brake roller 4. Since the tip of wire 20 is blown, it has a hemispherical and smooth surface, and the wire has linearity due to the Anneal effect.

'If the J trace mode is set, the rotation of the wire take-up roller 17 and the supply of machining power between the working electrodes 30a and 30b and the work W are started. The block start point indicated by the value of the pointer i is changed to the current position, and each axis is fed from the position based on the machining program (step S21), and the discharge discharge is performed. If the race mode is not set, only the feed of each axis is performed (Step S20), and the table 19 is moved along the program path to the machining position memorized when the disconnection is detected.

- the moving distance D between the start points of the breaks is smaller than the set value D 0, as described above, automatic connection is performed at an intermediate position between the break point and the start point of the block where the break occurred. Even if this is done, it is difficult to guide the wire to the lower guide because the machining fluid flow from the nozzle of the upper guide 7 is disturbed. Without performing automatic connection, proceed to step S11, and determine whether the block preceding the block in which the disconnection occurred (pointer i or the block that indicates') is an arc command.
- the command of the immediately preceding block may be a linear command.
- the block two blocks before (the block two blocks before the block where the disconnection occurred, and the point (The block corresponding to a value 2 smaller than the value indicated by the data i)) and its end point Pe2. That is, the start point Pe2 of the immediately preceding block is read (step S12).
- step S13 the moving distance D between the start point Pe2 and the end point Pel of the previous block is obtained (step S13), and the distance D is compared with the set value DO (step S13). If the value is equal to or greater than the set value DO, an intermediate position between the start point Pe2 and the end point Pel of the immediately preceding block is obtained, the table is positioned at the intermediate position, and the pointer i is set. Decrement "1" to indicate the previous block (Steps S15, S16, S17) o
- step S23 it is determined that the command of the immediately preceding block is a command for an arc whose radius r is smaller than the set value r0, and an automatic cut is made in a machining groove in the middle of this arc. If it is difficult to make the connection for the above-mentioned reason, and the step S14 sets the travel distance between the starting point Pe2 and the ending point Pe1 of the previous block. When the value is smaller than D0, even if automatic connection is performed at the intermediate point between the start point Pe2 and the end point Pel of the block, the machining fluid flow from the upper nozzle is disturbed, and the wire moves down the guide.
- step S24 If it is determined that it is difficult to guide to step S24, the process moves to step S24, and in this embodiment, the table is moved to the machining start hole, positioned, and the execution block is set. After setting the indicated pointer i to the value of the machining start block (steps S24, S25), the process proceeds to step S18. Automatic reconnection is performed at the machining start hole, and retrace is started from the block position indicated by the pointer value, that is, the machining start block, and when reaching the disconnection position, electric discharge machining is resumed. Top S18 ⁇ 22).
- the automatic connection when it is difficult to perform automatic connection with the processed groove of the block where the disconnection has occurred, the automatic connection is performed using the processed groove of the immediately preceding block.
- it is difficult to automatically connect the machining groove of the previous block it is necessary to return to the machining start hole and perform the automatic connection.
- step S11 the processing of steps S11 to S14 and step S23 is repeatedly executed. Specifically, the pointer i is decremented by "1" before the processing of step S11, and the block corresponding to the pointer i is decremented in step S11. At step S12, the end point of the block one before the pointer i is read, and the start point and the end point of the block corresponding to the point i are determined.
- the distance D is compared with the set value DO, and when the judgment power N 0 of step S 23 and the judgment of step S 14 are YES, Decrement pointer i by "1", return to step S11, and search for a block in step S14 where the travel distance D between the start point and end point is greater than or equal to the set value DQ It will be. If the moving distance D between the starting point and the ending point does not exceed the set value D0 in all the blocks, the process first proceeds to step S24. In this case, since the pointer has already been updated, the setting processing of the pointer i in steps S17 and S25 becomes unnecessary. ADVANTAGE OF THE INVENTION According to this invention, the retrace operation to the disconnection position performed after automatic connection is short, and electric discharge machining can be restarted in a short time.
