Claims

[Scope of utility model registration request]

During machining operation, there is a machined distance calculation means that calculates the machined distance from the machining start position to the position that has already been machined, and a look-ahead complete machining that calculates the total machining distance by pre-reading the NC program in parallel with the actual machining. a distance calculating means, a prereading end detecting means for determining whether or not the prereading of the NC program has been completed, and subtracting the machined distance from the total machining distance when the prereading end detecting means determines that the prereading has been completed. A wire cut electrical discharge machining apparatus comprising: a remaining machining distance calculating means for calculating a remaining machining distance; and a remaining machining distance display means for displaying the calculated remaining machining distance.
