Принадлежит:

The invention discloses a processing method for a numerical control machine tool of an electric sparkle forming machine. When an X axis and a Y axis shake, a processing electrode of a Z axis feeds or rolls back with certain speed in the vertical direction to replace traditional interpolation, namely the Z axis firstly moves to the given circle center position, and then the X axis and the Y axis move along a horizontal track. Therefore, due to the three-dimensional shaking feeding or rolling back during processing, discharging of processing scraps can be facilitated, and processing accuracy is further improved.

The invention discloses an electrical discharge machining electrode loss compensation method based on the opposite-forming principle. Before machining, a required electrode initial shape is reasoned out conversely according to a required ideal shape of a target workpiece and by the means of the electrode loss mechanism. The workpiece with the required ideal shape can be exactly machined out after electrical discharge machining of the electrode with the shape is accomplished and loss is caused. Namely, pre-deformation is performed on the electrode which is originally of the ideal target shape so as to offset the impact of the electrode loss and achieve the purpose of electrode compensation. In order to obtain the original shape of the deformed electrode, only the workpiece with the target shape is needed to be transformed to an electrode, the corresponding electrode is transformed to a workpiece, machining simulation is performed conversely, and the initial shape of the electrode can be ...
