Embodiment 6

[0121] Embodiment 6 of the present invention will be described below. In the above-mentioned Embodiments 4 and 5, a command trajectory is generated by the jump generation unit 1, which suppresses the frequency component values ​​in each frequency range to a predetermined value C or less. In this embodiment 6, a filter 15 is provided at the output stage of the jump control part 2, which is used to convert the resonance frequency f c Frequency component values ​​in the above frequency range are suppressed to a predetermined value C or less.

[0122] Figure 8 It is a block diagram showing the configuration of an electrical discharge machining apparatus according to an eighth embodiment of the present invention. exist Figure 8 Among them, the filter 15 is an analog filter, and the resonant frequency f c The frequency component values ​​in the above frequency range are suppressed to a predetermined value C or less and output. Other composition and figure 1 The configuration...

Abstract

An electric discharge machine is provided with a gap servo control unit for controlling the gap distance between an electrode and a workpiece while applying a prescribed voltage between the electrode and the workpiece, and a jump control unit for controlling a jump that allows the gap distance to be large temporally for a prescribed time or correspondingly to the machined state. The jump control unit is provided with a jump locus generating section for generating a smooth command locus having a frequency component within a prescribed frequency region not greater than the prescribed frequency or less than the prescribed frequency. The jump control unit controls a jump by using the smooth command locus generated by the jump locus generating section.

Description

technical field [0001] The invention relates to an electric discharge machining device and an electric discharge machining method which apply a voltage between an electrode and a processed object, and use the discharge phenomenon generated between the two electrodes to process the processed object, especially the electric discharge machining method. An electrical discharge machining device and an electrical discharge machining method that perform a jumping operation that temporarily increases the distance between poles every time a certain period of time passes or controls the jumping operation according to the processing state. Background technique [0002] In the past, the electric discharge machining device performed a jumping action after a certain period of time (that is, temporarily increasing the distance between the electrode and the workpiece), or performed a jumping action according to the processing state, and eliminated the accumulation on the electrode and the ma...
