Discharge forming machining method of workpiece interference inner groove and machining electrode

The invention discloses a discharge forming machining method of a workpiece interference inner groove and a machining electrode, and belongs to the technical field of discharge machining. The discharge forming machining method of the workpiece interference inner groove comprises the following steps that S1, an electrode is designed, and a corresponding discharge interval is calculated; S2, the electrode is machined and further mounted on an electrode holder, and the electrode is moved to an initial position; S3, the electrode is moved for rough machining, and then is returned to the initial position after machining is completed; and S4, the electrode is moved for finish machining, and then is returned to the initial position after machining is completed, so that forming machining of the workpiece is completed. The electrode holder is used for clamping and fixing the electrode, so that the electrode moves orderly to carry out rough and finish machining on the first inner groove and the second inner groove of t
