Description

【Technical field】 [0001] The invention relates to a method for establishing a wire cutting power curve mutation waveform feature library, in particular to a self-learning method for a wire cutting power curve mutation waveform feature library. 【Background technique】 [0002] Wire cutting uses high-frequency pulse discharge, and the gap is filled with working fluid. At this time, the cathode is loaded on the electrode wire, and the workpiece is loaded on the anode; the cathode escapes electrons, and the electrons hit the neutral particles of the working fluid during the process of moving to the anode under the acceleration of the electric field. , Neutral particles produce electrons and positive ions under the impact, and the generated ions and electrons join the impact process, and the ionization avalanche develops. When the working fluid is ionized and broken down, the electrons move to the anode, and the ions move to the cathode, forming a discharge channel and generating ...

Problems solved by technology

However, using methods such as manual judgment to identify the boundaries of each stage of the wire cutting power curve to distinguish different stages of the entire processing process is extremely inaccurate and the workload is huge

In addition, the NC code of the machine tool control system can also accurately find the boundary between each processing stage, but the control program of the machine tool has a protection mechanism, and the NC code is not easy to obtain and save data
