1 be based on parameter to change the product CAD products plan that proposes a standard to arrive from original concept end item is decided really, the modification that needs for many times commonly and optimize. Parameter is used to change a design to build a model in product CAD process, form parameter to change the 3D model of drive and 2D project plan. Because parameter changes a design to have the characteristic of strong associated sex, 3D model not only OK and intuitionistic the structural rationality that observes place of test and verify designs a product conveniently, and the kind that can carry modification drive parameter according to designing need at any time realizes pair of product figure models conveniently revise and optimize, save the energy of products plan engineer and time, raise work efficiency and products plan success to lead. Product CAD parameter is changed if the graph is shown 1 times,build a model, 3D piston model is shown 2 times like the graph. Graph 1 parameter changes the plan that build a model model of 2 pistons 3D 2.
Because differ,the information of 2 digitlization product is transmitted between the branch all the time since the software with different continue to use, traditional products plan information is transmitted downward through 2D blueprint. Because 2D blueprint cannot convey a design message completely sometimes, often cause design information to appear in transferring a process missing, change or different meanings circumstance, cause real product and design existence difference. And the information of digitlization products plan on SV software platform is reached through 3D model to it associated 2D project attempt is transmitted downward together, assured products plan information the integrality in transmission process, the design information that eliminates support 2D blueprint to transmit mode to may appear delivers an error. Emulate the process such as CAM of CAD of analysis, mould, mould to provide unified and complete 3D number for CAE at the same time model, reduced downstream process to build modular job respectively again not only, the height that also assured information of model of all flow product is unified, the information consistency that increases whole product flow and information are shared. Nextpage3 mould CAD delivers the 3D number model that come down by products plan, the develop that can pass entity conveniently on SV software attacks the 3D model that relation and relation of Boer gather operation form piston mould, the article is a specification with piston lumen mould only, if the graph is shown 3 times,attack for classics develop with the mould 3D model that forms after Boer operation. Graph CAD of 3 pistons mould is casting occurrence systole of the meeting in condensation process as a result of the piston, because this needs to be opposite beforehand when the mould is designed,contractive quantity undertakes compensating, the product measure after such ability assure to shape accords with a design to ask. The measure that SV software provides is put shrink the function can be measured according to the systole of the spare parts undertake compensating adjustment to mould dimension respectively on 3 different way, assure to shape actually thereby the dimension of the product accords with design dimension, resolve the difference that exists between mould and piston dimension conveniently. If the graph is shown 4 times,piston systole measures compensation. Graph the 3D model that quantity of 4 pistons systole compensates mould of piston of 4 moulds CAM and to it associated 3D project attempt transmits mould treatment downward, the CAM function module that SV software offers can the CAM of mould of timely implementation piston. Transfer into and open CAM module, set relevant and attrib border parameter (if semifinished product affirms, means of cutting tool choice, contrail) hind form treatment method automatically (if pursue 5) , will affirm cutting tool contrail through dogging to machining the trends of method, can examine the interference circumstance that treatment exists between bear case and examination cutting tool and workpiece to wait, affirm through a series of emulation and check, assure the validity of treatment and security. The course emulates an examination, through NC output founds treatment instructor. Through the aftertreatment relevant setting transmits the treatment that has piston pattern to CNC Machining center finally, realize piston mould CAM. Graph conclusion of method of 5 cutting tool relies on unified digital technology platform to realize CAD/CAM unifinication, the information in eliminating traditional technological process is transmitted not the circumstance of free and transmission medium confine, the function that SV software was over to have implementation unifinication completely on technical level and had carried out test and verify too. But want to carry out CAD/CAM unifinication in the round in the enterprise, will affect each each, cause bigger impact possibly to existing operation pattern, still need much auxiliary work. In the meantime, undertake user of deep administrative levels change development to software, make software platform more convenient the client's application also is the link that cannot neglect.
