Accurate digital control Electric Discharge Machining lathe is one of the important equipment of nontraditional precision machining technology, is mainly used for adding
Machining tool is difficult to superhard material and fragile material in work tradition, navigates to precision machinery, automobile, microelectronic product, aviation
The processing of it precision component and precision die is of great significance.Electrical spark working working hour with no cutting force, does not generate burr
And mark groove, Tool-electrode material are not necessarily to the features such as harder than workpiece material.
However during electrical discharge machining cutter, there are following points：(1) workpiece positioning is comparatively laborious, especially encounters
Irregular component is even more to bother.(2) tool-electrode is also lossy.(3) processing rear surface generates metamorphic layer；In some applications must
Further removal.(4) it can just be gone on smoothly under conditions of generating carbon slag and excluding carbon slag balance.(5) cutter or work when processing
The movement speed of part is slower, and compensation function operation is not the problems such as flexibly grade very much.
In addition, in mould discharging technology, the conventional mapping methods of workpiece and electrode are：Electrode and workpiece are first distinguished into clamping
It is corrected respectively on lathe, then on lathe, the coordinate system to ensure electrode and workpiece is parallel with lathe coordinate system；So
Afterwards, in dividing to the workpiece after correction, to find workpiece coordinate system (workpiece reference angle).Traditional localization method exists as follows
Problem：(1) due to needing to occupy the effective storage life of equipment in the enterprising luggage folder of lathe；(2) due to being divided on lathe
Middle work does not only take up the effective time of board, and on lathe point in using dial gauge, it is accurate in point
It spends low；(3) due to just can be carried out electric discharge in needing to be corrected the electrode of each electric discharge, dividing, effective processing of board is wasted
Time.In short, conventional mapping methods can not ensure the repetitive positioning accuracy of workpiece and electrode, and along with very in operating process
More subjective judgements can be brought uncontrollable to mold processing quality.In addition the correction of electrode and workpiece, point middle work can waste largely
Time so that mold manufacturing speed can not fast lifting.Mold processing quality is required with the phase of friendship along with people continuous
