With treatment of software of V2 of CAXA line cut

As the ceaseless development of Chinese manufacturing industry, cut of electric spark line (cut of line of the following abbreviation) the application in manufacturing industry is wider and wider also. Line cut is OK the conductor of cut tall hardness, as the development of numerical control technology, OK and quick cut gives line cut the part that has complex figure, it is special the development that applies to new product, can charge of greatly managing tool, shorten new product development is periodic. But line cut treatment is put in an inherent problem, that is the spare parts after line cut apparently, bequeath catchs fire when the flower discharges, be fused caky metal layer fuses namely layer. Fuse raw base metal of layer and spare parts is compared, hardness is reduced, some surfaces still have micro-crack. Micro-crack machines the fatigue intensity of the spare parts to have adverse effect to place, this pair of great majority do not have any influences for common product, but be like aviation manufacturing industry to a few essential industries, must consider its to affect. Involute spline (spline of the following abbreviation) the important link that is aviation accessory, spline of small modulus of aviation accessory product is particularly much, in small modulus spline, the treatment of the spline inside small modulus compares difficulty again. The treatment method of the spline inside traditional small modulus is land belonging to one production unit but enclosed in that of another key or garland key commonly, as a result of modulus product lumen is small, small, spline slotting tool and spline broach all are compared fine, tigidity is too poor, treatment is difficult, a lot of cutting tool cannot be made almost. And the product to above of HRC38 of hardness prep above, spline broach and spline slotting tool all cannot be machined, be forced to choose line cut to undertake machining. To these important parts, the fused layer of spare parts surface must keep clear of after line cut. The article above all the process that brief introduction uses the spline inside treatment of software of V2 of CAXA line cut, surface of the spare parts after introducing cleared line cut next is fused a kind of device of the layer. One, with software of V2 of CAXA line cut the spline inside treatment is before software of V2 of cut of use CAXA line, we use manual process designing commonly in online cut treatment, to spline kind spare parts, we wrote a program technically still to calculate with Basic language spare parts contrail, this kind of method is used rise quite trival, the spare parts of different figure should write different program. After software of V2 of cut of use CAXA line, the circumstance got complete change, CAXA is very OK conveniently the treatment contrail that scale gives a part, create line cut machine program. Below with pitch P=40 (namely modulus M=25.

4/40=0.

635) , the spline of 30 ° of tine number Z=29, pressure angle ＝ is exemple, will explain its machine a process. Start software of V2 of CAXA line cut above all, click " scale " menu, choose " advanced curve " , choose " scale spline " , with respect to the dialog box that can see scale spline. Fill in the dialog box on spare parts parameter. Click " next " , occurrence dialog box, fill again on click after the other parameter of the spare parts " finish " , receive a demand namely inside spline graph. After spline contrail is generated inside, through " orbit is generated " , " jump the pace is installed " wait for a series of operations, software of CAXA line cut can create 3B code program. Input 3B code program line cut machine, can have the treatment of the product, length of be confined to is relevant detail no longer expatiatory. Software of V2 of CAXA line cut besides have scale the curve such as linear, round, gear, implementation line is cut, transfer round horn, translation, duplicate, dimension is tagged outside waiting for a function, still can the basis needs scale formula curve. This function is particularly practical, accordingly but scale gives all curves that can give formula, the curve that scale gives and other and linear or circular arc classics a series of editors, the contrail that attainable user place needs. The interface of formulary curve. Producing actual in, we often come up against a few nonstandard spline, can give line cut contrail to come with this function scale. 2, surface of line cut treatment fuses the cleared line cut of the layer machines the surface to fuse the deepness of the layer is commonly 0.

015 ～ 0.

04mm, to reduce fused layer deepness, the treatment electric current with optional minor cutting rate, lesser choose and lesser pulse width. But no matter how the deepness of fused layer is small, always be surface of consist in spare parts. The fused layer that with abrade law cleared line cut machines the surface ever was recommended in concerned manual, this kind of method is like plane to a few simple surfaces, inside aperture is abrade rising is more convenient, but internally this plants spline model the face undertakes abrade compare difficulty. Pass internally the analysis of spline characteristic, abrade law comes to clench the teeth of our make choice of cleared and fused layer, what use a same parameter namely is cast-iron outside spline, pass the clench the teeth of spline of inside and outside, sum an axial campaign, grind go inside the fused layer of spline surface. Next mask body explain its machine a process. This machine tool that abrade process uses is common lathe, abrade device installation is on the tool carrier of lathe, arbor clip holds cast-iron spline to go up in abrade device. Car fillet moves a product to rotate, of the product inside spline drives cast-iron spline arbor to rotate. There is cam of an end panel in abrade device, when outer spline begins to rotate, end panel cam bolts cast-iron flower heart axial is advanced by interior of abrade spare parts ceaselessly, in the meantime, there is the one spring with connection of spline arbor photograph on abrade device ceaseless by drawing, crossed certain route, reach cam culmination, cast-iron spline arbor begins below the action of bedspring from in outward motion, arrive at the nadir of cam, complete a journey thereby. In abrade process, handlers is in process of spline arbor campaign, join often fresh and abrade cream, the deepness that the handling time of every product changes a layer by frit, abrade the factor such as the degree of finish that cream is certain, obtain through trying treatment method commonly. Adopt above device, better land came true inside of spline surface abrade. This method equipment is simple, the operation is convenient, cost is very low also, solved one of generate real problem, widened at the same time the size range of pipe bent of cut of electric spark line.
