Technical field
The invention mainly is applicable to adopts the plate digital control processing, and the edge strip outside is fluted, and the edge strip termination opens wide, and edge strip thickness≤2mm, highly＞and the part of 40mm.
Background technology
At aviation field, fluted to the outside, the termination opens wide; And thickness≤2mm, highly＞problem that exists in the edge strip part processing of 40mm is: at first, between edge strip outside groove and woollen baseplane apart from less; If directly on platen, use machine tool chief axis pivot angle machined grooves; Therefore lathe headstock can interfere with workbench, processes part that this type of edge strip outside has groove and all be with woollen baseplane and side plane as positioning reference, processes all sites except that groove; Use square chest or other working position apparatus bed hedgehopping parts then, again with part baseplane and the datum hole that processed as positioning reference processing edge strip outside groove.Employing the method processing, the workman needs the lifting station utensil, has increased production time, and variation has taken place the positioning reference that machined grooves adopted, and influence the accurate of groove location.Secondly; The part that the edge strip termination opens wide all is to adopt first processing parts profile, and promptly first cutting-off part and border woolen cloth are connected to form the part largest contours, the method processing of back processing edge strip thickness; The method can not go wrong when edge strip thickness＞2mm or edge strip height≤40mm; But when edge strip thickness≤2mm and height＞40mm, the steadiness that edge strip is opened wide end reduces, and work in-process can produce bigger vibration; The edge strip thickness that makes this place easily becomes defective work less than the minimum dimension that product design requires.The 3rd, when the processing height approaches edge strip, all be through the elder generation processing edge strip outside, processing inboard acquisition edge strip thickness, the mode of the processing of layering is from high to low all adopted in both sides.When edge strip thickness thickness≤2mm and height＞40mm, edge strip processes the outside and causes the edge strip rigidity to reduce, and edge strip trembleed when processing was inboard, was attended by the cutter vibration simultaneously, caused edge strip surface roughness variation.
Summary of the invention
In order to overcome the above problems, the invention provides a kind of and is applicable to that the edge strip outside is fluted, and the edge strip termination opens wide, and edge strip thickness≤2mm, highly＞and the numerical-control processing method of the part of 40mm.
The technical scheme that the invention is adopted is: the numerical-control processing method of the thin-walled parts that band side groove termination opens wide is following:
1) processing of edge strip outside groove: with woollen baseplane and side plane as locating benchmark; The edge strip profile of the fluted side of elder generation's roughing; Change woollen modes of emplacement then; With original side plane as the baseplane; The baseplane is as side plane; Still process groove as the location benchmark, again woolen cloth is returned to former modes of emplacement with these two planes;
2) processing of opening wide end of edge strip: during the processing parts profile; Process the part except that edge strip is opened wide the termination earlier; Keep edge strip to open wide end and woollen being connected in border; Under this state, accomplish the processing of edge strip thickness; Cut off edge strip again and open wide end and woollen being connected, form edge strip and open wide the end profile;
3) processing of edge strip thickness: adopt and alternately to process outer, the inboard method of edge strip, accomplish one deck processing back in the edge strip outside then accomplish the inboard one deck processing of edge strip, so back and forth, final acquisitions need edge strip.
The beneficial effect of the invention is: 1. adopt the processing method of edge strip of the present invention outside groove, processing edge strip outside groove need not to use working position apparatuses such as square chest, has saved the required working time of workman's lifting station utensil, has improved part processing efficient.In addition, this method processing edge strip outside positioning reference that groove adopted is consistent with the positioning reference that adopt at other positions of processing, has eliminated the position error that the positioning reference conversion is brought, and the edge strip that processes outside groove location is more accurate.2. adopt edge strip of the present invention to open wide the processing method of end; When processing parts edge strip thickness, kept edge strip to open wide end and woollen being connected, when cutting proceeded to edge strip and opens wide end, the vibration of edge strip generation conducted to the border woolen cloth through connection; Thereby vibration intensity is weakened; The edge strip steadiness improves, and guarantees that edge strip opens wide end thickness and satisfy the product design requirement, obtains qualified products.3. adopt the processing method of edge strip thickness of the present invention; The rigidity that in process, has kept high thin edge strip to greatest extent; The vibration and the cutter that have reduced the edge strip work in-process tremble the influence that edge strip caused, and guarantee that edge strip obtains the surface of good roughness.
