Pro/E parameter changes a technology to apply mediumly in punch model CAD

The 1 parameter that is based on Pro/E changes a design to develop measure to be based on the parameter of Pro/E to change design development to have 3 move commonly: ① uses the hypostatic modelling of Pro/E and parameter drive function, the ② of the; that build a model that has a part undertakes parameter to the model that builds, and set of the relation between parameter, the need that satisfies parameter drive thereby, the tool that menu pulls to undertake; ③ uses Pro/E to offer below the relation in using tool bill of fare undertakes parameter changes design development. 3.

2 parameter turn design development and application (when 1) a group of things with common features expresses technical application to be designed in the spare parts, if certain part structure is same, it is dimension differs only, so these spare partses need not one by one individual build, can build part of a father, the definition controls the parameter of size of spare parts shape individually, get what what need derive when the design through changing the value of each parameter, build thereby a series of spare parts, the gather that these spare partses form calls a group of things with common features list. Because the structural appearance of standard component and dimension had been standardized, reason mould designs the standard component library in the system to use development of technology of a group of things with common features watch, achieve design goal convenient and quickly thereby, graph the 3 interfaces that design a part to use a group of things with common features list. Should notice when building father part the following 2 problems: ① father spare parts uses the standard component with the largest size in be the same as type standard component commonly. ② father spare parts should include all features that are the same as type standard component. (The applied Pro/Program of 2) Pro/Program technology is a file that records a model to establish a procedure, it is recording the move that the model produces and condition, those who include all features establish the model information such as process, parameter, dimension and relation, the system keeps the information of every built feature in the program, the user can pass the feature that edits very simple program language to change a part. Pass " Program " the occurrence that can control the feature in the spare parts, the occurrence of the spare parts in the size of dimension and assembly parts, a number of the spare parts, thereby very the product that designs a series of differring conveniently. As a result of commonly used structural appearance and measure are more similar, reason uses Program technology to undertake the mould designs systematic middling to use the development of a library. Pro/Program program forms by 5 parts order: Relation of information of clew of program title, input, input, add a feature (or spare parts) , with quality character, the user can input clew information section according to needing to be in (adaptable parameter name is added between INPUT and END INPUT) can. (The parameter that 3) is based on Pro/Toolkit to develop changes design technology application to be based on Pro/Toolkit three-dimensional parameter to change the development method of the design to have 2 kinds: The rock-bottom function that benefit of law of description of ① application feature provides with Pro/Toolkit finishs a feature to build a model, build man-machine interaction frame, realize three-dimensional parameter to change a design, this method programming is trival, for complex to appearance product, it is very difficult to become three-dimensional model with program a future life the means that; ② uses three-dimensional model and band of programme controll photograph, basic course builds three-dimensional model to interactive mode is used below Pro/E environment, the spare parts that already founding next is three-dimensional on the foundation of the model, according to the design of the spare parts the requirement builds a group to be able to control the design parameter of three-dimensional model appearance and size completely. Parameter changes a program to undertake process designing in the light of the design parameter of this spare parts, the retrieval that realizes design parameter, function that revise and builds new three-dimensional model according to new parameter worth, its flow is shown 4 times like the graph. This kind of method can build the product model with complex form, process designing is opposite for simpler, be used by broad developer. Undertake with programme controll model three-dimensional parameter changes the development of the design, basically include 3: Get and show the replaces modification; model second birth of; parameter object of parameter object. Graph 5, graph a 6 case that develop to use place to narrate a method. Graph 5 for model of spare parts model, can change among them one parameter size undertakes spare parts renascence, still can choose parameter series value to undertake spare parts renascence from inside list, graph 6 it is namely circumstance of spare parts of the renascence after ply instead 50 Min. 4 epilogue parameter changes a design is CAD technology the task that offers in applying actually, use parameter to change design method not only can develop system of special products plan, the parameter that still can have a product changes a design, the disengagement in making design personnel to work from a large number of onerous and trifling designs thereby comes out, design of relaxed implementation hardware, mould design, when assembling design, treatment design to be equal, undertake, accelerate a mould to design a process, shorten design, production cycle, enhance new product to develop ability, enhance market competition ability.
