In the electric discharge machining, there is always electrode wear. If the machining sequence is always performed in the same direction while changing the electrodes from roughing to finishing, the electrode consumption will gradually increase twice and three times at the second and third locations, and the machining depth will be large. The amount of wear increases as the roughing process is performed, and the final process is the worst.
Further, since the discharge frequency is high also in the corner portion of the electrode, the corner portion of the electrode is gradually rounded in the machining order in a constant direction, and the corner R becomes larger toward the last machining position, and the shape accuracy is deteriorated. Therefore, in the electric discharge machining, it is desirable to change the machining order when the electrode is replaced. For example, when the electrodes are exchanged, if the processing order is reversed, the processing accuracy is high and a processing result with little variation can be obtained. Further, it is desirable that the change of the processing order is automatically performed.

When the change data of the processing pattern is input to the processing data input means, the processing data setting means automatically sets the processing order corresponding to the processing position based on the change data. When the change data is input to the processing data setting means, the processing order erasing means outputs to the processing data registration means a command to delete the processing order registered in the processing order registration table of the processing data registration means. The processing data registration means groups the data set by the processing data setting means into one group for each processing position, adds the processing order to the group, and registers the group in the processing order registration table.

Reference numeral 3A denotes processing data setting means for setting data of each item from the processing data input means 2A as processing data. At this time, the processing order at the position of each processing point is set based on the combination of the input processing patterns. In this processing order, the processing order corresponding to the processing position is determined based on the previously specified processing pattern, and the processing pattern specified later is calculated from the next value of the last processing order of the previously specified processing pattern. The processing order corresponding to the processing position is determined based on the processing pattern. When a processing pattern different from the previously set processing pattern is input from the data input unit 2A, the processing order of the positions of the processing points is set by a combination of the processing patterns in the same manner as described above. that time,
Depending on the combination of each processing pattern, the processing order is also set sequentially at the place where the data is not set in the specified items of the workpiece and the electrode. The processing data in the next processing order is output without processing data being processed. That is, the processing order of a portion not specified in the specified item is skipped.

In step 21, the processing data setting means 3A determines whether or not a processing pattern designated item different from the processing pattern previously set is input (the processing data input means 3 via the input unit 1). It is determined whether the processing pattern 23c has been changed using the data setting area 23 of 2A). If the same processing pattern or the processing pattern in the initial state has been input, the process proceeds to step 26, and a different processing pattern is input. If yes, go to step 22.

In step 22, the processing order erasing means 5 clears the processing order data registered in the processing order registration table of the processing data registration means 4, and proceeds to step 23. In step 23, the processing data setting means 3A sets each processing position (processing point) of the workpiece so as to have the maximum number of points, and proceeds to step 24. Step 24
In step 25, the processing data setting means 3A sets the number of electrodes to be used for each processing point of the workpiece to the maximum, and

In step 26, when each processing pattern is set without using the data setting area 23 in step 21, the processing data setting means 3A determines the position of each processing point based on the combination of the input and set processing patterns. The processing order is set and the process proceeds to step 27.
In step 27, each processing data (for example, processing pattern, processing position, processing sequence, workpiece, used electrode, processing depth and processing conditions) set by the processing data setting means 3A is stored in the processing data registration means 4 In the machining order registration table.

As described above, even if each processing data is registered, each processing pattern of the processing data is changed, and the processing order is automatically arbitrarily written for each processing point based on the combination of the processing patterns. As a result, the operator does not need to input all the processing data again, so that the input operation becomes very easy and the program can be simplified.
