Through introducing the system of Think3 company, the company of die manufacturer Attrezzeria Paganelli that comes from Italy can shorten the time that produces medium-sized pattern 25% , shorten by 13 months in the past 10 current months. The competition of domain of international auto industry is increasingly intense, force manufacturer to must shorten the development cycle of new product and market guide periodic. Consider at the same time reduce specific power consumption and the demand that provide the field such as lighter, safer car, the use of high strenth rolled steel and aluminium alloy and complex part also becomes a trend gradually. The scope of application of this sort material expands gradually, to treatment the enterprise brought greater and greater pressure, so that the engineering technology with the cost that makes its must reduce plank processing ceaselessly, ceaseless new development processes new-style, smoother, more complex data. The Attrezeria Paganelli company that comes from Italy should face the demand of such everyday, this company main production is small-sized, medium-sized the punch mould with large size, the plank cold processing in be auto industry for instance and relevant supplier offer a mould, and manufacturing cupping mould and appearance. Be located in the job shops of the Attrezzeria Paganelli company near Milan. The whole world that business of this mould production issues at getting masses automobile group 2006 is optimal processing manufacturer certificate. The treatment that assures spare parts of data quality plank below spring back setting basically relies on a mould to undertake processing and be finished to material. Should take out a spare parts to face spring back phenomenon with respect to meeting: The status before metabolic spare parts can be machined forward appears tilt trend, deviation appears between the dimension that this kind of stretch deformation will cause spare parts and hope. The spring back phenomenon when material of use high strenth will be more apparent. To reduce spring back phenomenon need uses sundry technology, but the method that has not found a kind to be able to eliminate spring back appearance completely up to now. Attrezzeria Paganelli company makes at optimizing the flow of processing successfully its achieved standardization, reduce the design time of the mould and cost significantly thereby. This company used Think3 company to develop " compensator " system -- a kind of CAD that is used at mould design amends plan, its are main the principle is in be based on spring back process finite yuan the analysis comes to shaping exterior change brings to bear on influence. The supplier offers the treatment technology that the basis differs on the market corresponding compensation system program, in order to undertakes necessary correction to exterior model. Can be opposite through this kind of means brings as a result of data quality adverse effect undertakes compensating, and the fall of data quality often can bring about stretch spring back of systole of other perhaps such as and evaginate be out of shape means. According to a stretch spring back finite yuan of analysis result, compensator system will be mixed to CAD model finite yuan the analysis undertakes comparing is opposite as a result. If two data not conform to, will calculate so a corresponding compensation and reach as a result according to computation new CAD model. The global form that Think3 company develops builds modular technology (GSM3, global Sahping Model) can generate data of course compensatory surface automatically. From this, the quality of this surface and develop attack to the structure is beginning and end level to keep consistent (even if class A surface) , also need not use converse project technology so. The curve that close: Think3 company was based on the system of ThinkDesign series CAD of this company to develop compensator plan, fill finite of yuan of analysis forecast result and processing to optimize the huge wide gap between demand. The technical development of Attrezzeria Paganelli company is in charge of Mr Corrado Vergani to say: "The huge advantage of compensator system depends on: Because ensured the product is developed,the standardization of the process is mixed but repeatability, can build CAD surface model automatically thereby. The data of output and BREP (Boundary of expression having a group - Representation) hypostatic model keeps compatible, and the surface can keep successive. In addition, this system can use all sorts of analysis tools: The indication of area of quality inspection, clearance examination, fill and color change. Because need not make hypostatic appearance, can get thereby relatively optimized imitate level, make photograph comparing with pure handiwork, also can reduce time cost and capital cost greatly. " before, make large shape the mould needs 13 months on average. Have the aid of of Attrezzeria Paganelli company makes at compensator its shortened 25% , that is to say, time limit for a project shortens from 13 months for 10 months. User brief introduction: Attrezzeria Paganelli company had passed ISO9001-2000 and AVSQ-MIA attestation, basically be small-sized, medium-sized with large board Leng Yacheng treatment produces a pattern. The pattern that this company produces applies extensively at the large car manufacturer of world each district. The company is located in the Cinisello Balsamo near Milan, cover an area of an area to make an appointment with 52000 square metre, floor area makes an appointment with 29000 square metre, employee a total 360.
