A kind of processing method improving abnormity intersection hole, which is characterized in that including following aspect:
A. drilling optimization is carried out by the sequence of drill flute after first drilling；
B. intersecting is edge PTH hole at hole, designs unhairing acanthopore, herein subdrilling burr hole, knife sequence arranges foremost；
C. intersect at hole, be designed as requested using slot knife and slot knife parameter at slot.
Further, the burr bore dia is 0.5-1.0mm, and burr hole section width is 0.3-0.6mm, at 30-60 °
Oblique angle.
Further, if the burr bore dia is 1.1-1.5mm's, knife sequence is arranged after burr hole.
Further, if the slot diameter is 0.4-0.8mm, slot selection is last to be bored, and knife sequence arranges last.
Further, production process has distinguished the cutter of hole and slot in advance, and calls corresponding parameter data, can shift to an earlier date
Bad caused by preventing because of parameter misuse, the brill nozzle and slot knife drilling parameter for intersecting hole need to manage.
By a large amount of creative test discoveries of present inventor, anisotropic being mainly shown as occur, hole slot intersection macropore is inclined
Position, main cause are caused by the hanging hole location beat of hole location.Present inventor combine production efficiency under the premise of, according to
A kind of technique for improving abnormity intersection hole is found out in cutting tool choice, different-diameter hole and the optimization of slot knife sequence, critical technical parameter
Method.
The present invention is under the premise of original working condition, and by reasonably optimizing parameter, programming, realizing improves special-shaped phase
Groove/opening is handed over, to improve production efficiency, reduction is scrapped.The present invention rationally changes original drilling by the optimization to cutter knife sequence
Mode improves production efficiency with the smallest investment and obtains maximum quality improving and scrap cost saving.
