         EDM small hole milling process
        1, EDM milling machine milling methods: In the contour processing or grooving processing can be selected to generate arc segment program. In the process along the curved surface must be selected straight line processing, including cutting into the program, that is, the program segment must be a spatial micro-linear segment, which is also conducive to electrode loss compensation calculation.
2, EDM small hole machine milling allowance: The minimum value of the parameter is greater than the discharge gap, the processing allowance is not zero when the super-finishing, and the previous process to leave a margin to the next process.
3, EDM milling machine milling. The higher the machining accuracy, the higher the degree of approximation of the chord line to the space curve, the more spatial micro-line segments and the longer the program. During actual machining, rough machining can be selected with a lower accuracy to reduce the number of program blocks.
4. Residual peak height: This parameter refers to the horizontal feed of the tool. The smaller the value, the smoother the machining surface. This parameter can also be expressed as a percentage of the tool diameter.
5, electrode size: This article requires the actual input electrode diameter measured during each programming, so that the electrode loss compensation calculations only need to be placed in the z-axis direction.
6, electrical parameters and electrode length compensation: the choice of electrical parameters to reference the machining allowance, ultra-precision machining to choose the positive processing method, to use electronic energy to repair the flattening of the discharge marks. The electrode loss compensation value depends on the process experience. It is related to the electrical parameters, the electrode material pair, and the working fluid. The electrode loss compensation value is evenly inserted at the end of each microline segment.
