4 the processing of innovations
4.. 1 the clamping technology aspects
General thickness workpiece machining taper all in 0 ~ 30 °., and for most 100 ㎜ big thickness of workpiece, limited to stoke scope machine. Only to 15 ° processing taper, the maximum to 25 °. The abnormity bores machining difficulty for 41 °, part thickness of 30 ㎜, makes processing difficulty bigger.
The workpiece, the following two row holes abnormity (above 6 ㎜ 6x8 ㎜ rectangular hole, below 8 ㎜ x 6 ㎜ rectangular hole), to find the same processing benchmark for workpiece machining. Use "quadrilateral points in" method, find the workpiece center, as two rows of abnormity bores processing benchmarks.
Because the abnormity bores 41 ° bigtaper, wear silk hole is 41 °. Generally the punching machine can become Angle, processing the wear silk hole should do a special tooling. Now through the 3d model to machine tool, the workpiece imported by decomposing 41 ° in Y and Z direction of workpiece rotation Angle, one is 39 °, one is 10 °, according to this 2 Angle made two cushion block, the workpiece pad to need up 41 ° taper, thus smooth after this particular to wear silk hole.
4.2 two-step secondary cutting method
A cutting with general method to processing the abnormity bores, scraps can't access, now write 2 program, 6 ㎜ x 6 first processing ㎜ hole, processing after six ㎜ 6x8 ㎜ holes, so that, in two steps will not remove six ㎜ x 6 ㎜ square, the remaining scraps to exclude it easy to take out of scraps.
4.3 optimization process parameters
Try processing process, because 41 ° big processing taper. Is on, under the guidewire mouth stagger, cause working liquid can't flush the machining parts, appear broken wires, especially in the wire electrode walk to abnormity bores the corner is especially remarkable. The original expert system that initial processing parameters set cannot satisfy so large Angle processing. Through the analysis of the process parameters and combining the processing condition, machine itself of electrode wire feeding speed, tension, pulse intermission, processing frequency repeated modifying and try cutting, eventually selected a set of suitable processing technology parameters, successfully completed abnormity bores processing.
5 closing
Summer mill technology company production of "ROBOFIL 240SL" good-bye silk thread cutting machine, machining precision and surface quality is higher. But the parts due to processing has particularity, use the conventional processing methods are hard to guarantee the precision and surface quality. Through the design special tooling realize parts wear silk hole processing; Through the test electrode wire cut to optimize pulse power parameter and machine parameters, eventually completed the large Angle, under the abnormity bores take care of wire cut. And to achieve the required size accuracy and surface roughness, namely dimensional accuracy and surface roughness 0.005 ㎜ Ra0.4 muon m.
