Definitions
- This invention relates to a wire electric discharge machining apparatus.
- the wire electric discharge machining apparatus arranges a wire electrode and a workpiece (workpiece) so as to face each other, generates a pulse discharge in a machining gap between the wire electrode and the workpiece, and uses thermal energy to remove the workpiece. It is an apparatus for processing into a desired shape.
- wire electric discharge machining in order to improve shape accuracy, first, rough machining is performed, and then finishing is performed a plurality of times.
- the corner portion often has a lower processing accuracy than the linear portion formed by relatively moving the wire electrode in the linear direction.
- the corner portion is a portion formed by changing the direction in which the wire electrode is relatively moved, and is processed by relatively moving the wire electrode along an arcuate locus. For example, in the case of in-corner machining in which the wire electrode is moved inside the corner portion, the amount of machining between the previous-stage machining surface and the current-stage machining surface is increased compared with the case of machining a straight portion. It is easy to leave behind. Further, in the case of out-corner processing in which the wire electrode is moved outside the corner portion, the amount of processing is reduced as compared with the case of processing the straight portion, so that excessive corner portion is likely to occur.
- Patent Document 1 proposes a technique for controlling a processing speed when processing a corner portion according to an increase or decrease of a processing removal distance (removal allowance) for the purpose of improving processing accuracy.
- the machining removal distance is the length of the perpendicular line drawn from the intersection of the discharge gap circle (the radius of the cross section radius of the wire electrode plus the discharge gap) and the previous process surface to the current process surface. , Approximate to the above-described processing amount.
- Patent Document 2 discloses a machining condition using a function whose variable is an arc radius of a wire center trajectory for relatively moving a wire electrode for the purpose of suppressing a slack (deviation) and a remaining amount of a machining shape within a predetermined range. A technique for determining the above has been proposed.
- the wire electrode When the workpiece has a high thickness or when the machining fluid nozzle for injecting the machining fluid is located away from the workpiece, the wire electrode may bend or escape. If the wire electrode is bent or escaped, the machining removal distance calculated geometrically differs from the actual machining removal distance. For this reason, in the technique of Patent Document 1, it may be difficult to improve the machining accuracy even if the machining speed is controlled according to the calculated machining removal distance.
- the machining accuracy can be improved by correcting the machining condition according to the arc radius of the wire center locus.
- the arc radius of the wire center locus changes depending on the offset amount from the program locus stored in advance in order to obtain a desired machining shape. For this reason, even if the target final machining shapes have different arc radii, the wire center trajectory may be the same arc radius in any of the finishing stages.
- the present invention has been made in view of the above problems, and wire electrical discharge machining that enables high-precision machining by correcting machining conditions with reference to a program trajectory in order to obtain a desired machining shape.
- An object is to provide an apparatus.
- the present invention generates a discharge between the wire electrode and the workpiece, and moves the wire electrode and the workpiece relative to each other to the workpiece.
- a wire electrical discharge machining device that performs electrical discharge machining, and each machining stage in which the wire electrode is moved on a wire center locus offset from a pre-stored program locus to obtain a desired machining shape and the offset amount is changed.
- the machining conditions for each machining step are set according to the arc radius of the portion corresponding to the corner portion of the program trajectory. It has a processing condition correcting means for correcting.
- the machining conditions for each machining stage are corrected with reference to the program trajectory, so that the corner parts that need to be corrected are not affected without affecting the machining of the corner parts that do not require correction. Only machining conditions can be corrected. Thereby, there exists an effect that high processing precision is obtained especially about the processing shape provided with a corner part.

It is offset away from. As described above, in the corner portion finishing, the offset amount of the wire center locus is changed for each processing step.

For this reason, if the processing speed is constant between the straight line part and the corner part, the left part is left behind in the corner part with respect to the straight line part.
