[0064] The present invention is to improve the processing accuracy of the concave corner (the concave corner formed by two intersecting moving blocks) in the multi-pass machining of finishing. In order to improve the processing accuracy, according to the present invention, such as figure 2 As shown, based on the processing characteristics of the concave corners in the multi-path processing, the problem is solved by designing and changing the processing path including the insertion of the circular arc motion block.
[0065] The following will refer to Figure 4 Describe the method of the present invention. According to this method, the problem is solved by inserting the arc block into the concave corner of the shape of the program command. Figure 4 It means that the arc block is not inserted into the nth machining operation of multi-path machining but the (n+1)th machining operation. In the nth machining operation, the wire electrode moves linearly along the "nth wire center path...
