Description
Technical field
The present invention relates to a kind of method applying rearmounted program reverse modeling, in the digital control processing of the large-sized structural parts lacking digital-to-analogue.
Background technology
The flow process of product Top-Down Design be from conceptual design start to walk CAD modeling, numerical control programming, digital control processing, eventually form new product, but for complicated product, forward design method shows has located deficiency, design process degree-of-difficulty factor is big, the cycle is longer, cost is high, it is unfavorable for the development of product, because product cannot be estimated completely there will be which type of problem in the design, organic growth the method that defines reversal design the most in this context.
General reverse modeling uses method to be to utilize three coordinate measuring engine measurement inspection jig and exemplar profile, CAD software point cloud function is utilized to form appearance curved surface, rely on a formation line, again with the simulation approximation theory in line formation face, this is the process of an analog quantity transmission, inspection folder error, measurement error, the calculating error these three deviation accumulation of some cloud order get up, necessarily lead to certain error, approach so the curved surface after reverse foundation is a simulation, digital-to-analogue can not need trial cut to verify as directly processing foundation.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of method applying rearmounted program reverse modeling, the method carries out reversal design based on rearmounted program, produce the digital-to-analogue of part to be processed, the method accuracy rate is high, workable, technically reliable, not only shorten the design of product, construction cycle, reduce cost and the risk of enterprise development new product.
For solving problem above, the concrete technical scheme of the present invention is as follows: a kind of method applying rearmounted program reverse modeling, comprises the following steps:
1) use numerical control to survey cutter instrument cutter is accurately measured, determine cutter parameters；
2) cutter parameters, woollen parameter and coordinate system after measuring are input in rearmounted program, and this rearmounted program is updated in the numerical control machining simulation system VERICUT software of CGTECH company of U.S. exploitation, it is simulated demonstration by Export Model function, to demonstrate result Export Model fuction output IGES formatted file, this document obtains the patch digital-to-analogue of part to be processed；
3) open IGES formatted file with Catia V5.0 software, patch digital-to-analogue is generated new three-dimensional digital-to-analogue；
4) newly-generated three-dimensional digital-to-analogue is substituted in VERICUT software, and utilize rearmounted program to form cutter path in newly-generated three-dimensional digital-to-analogue, cut by the mistake in three-dimensional digital-to-analogue and judge the difference with actual parts with remnants, and be adjusted, thus generate the three-dimensional digital-to-analogue consistent with actual parts.
The method of this application rearmounted program reverse modeling can be three-dimensional digital-to-analogue by the original rearmounted Program transformation of part by VERICUT software, not only increase the design of product, construction cycle, and three-dimensional digital-to-analogue can be changed arbitrarily, to reach the purpose of part optimization processing.

Detailed description of the invention
A kind of method applying rearmounted program reverse modeling, comprises the following steps:
1) use numerical control to survey cutter instrument cutter is accurately measured, determine cutter parameters, because rearmounted program depends on the profile of cutter, only accurately enter cutter parameters, the digital-to-analogue that numerical value is correct could be obtained in follow-up simulation software；
2) cutter parameters, woollen parameter and coordinate system after measuring are input in rearmounted program, and this rearmounted program is updated in the numerical control machining simulation system VERICUT software of CGTECH company of U.S. exploitation, it is simulated demonstration by Export Model function, to demonstrate result Export Model fuction output IGES formatted file, this document obtains the patch digital-to-analogue of part to be processed；
3) open IGES formatted file with Catia V5.0 software, curved surface is converted to entity PART form, patch digital-to-analogue is generated new three-dimensional digital-to-analogue；
4) newly-generated three-dimensional digital-to-analogue is substituted in VERICUT software, and utilize rearmounted program to form cutter path in newly-generated three-dimensional digital-to-analogue, cut by the mistake in three-dimensional digital-to-analogue and judge the difference with actual parts with remnants, and be adjusted, and notice that mistake here is cut the digital-to-analogue coin actual parts meaning to set up and wanted big, and need to revise little, remnants then represent that digital-to-analogue is little, need to strengthen, thus generate the three-dimensional digital-to-analogue consistent with actual parts.
As it is shown in figure 1, by tool diameter, the half that data are tool diameter that part theory outer rim is cheap can be calculated.
