3、cad / cam / cae integration software. the pro / engineer software for parameterization parameter technology the earliest application by the current three-dimensional modeling software, possession with an important position of pro / engineer as a new standard for todays world machinery of cad / of ca

4、e / the cam fields and get the industry recognition and promotion. is now one of the mainstream cad / cam / cae software, in particular, occupy an important position in the domestic field of product design.pro / e first proposed the concept of parametric design, and uses a single database to solve t

5、he problem characteristics. in addition, it uses a modular approach, users can choose according to their needs, without having to install all the modules. pro / e based on feature, the ability to design to production to the whole process of integration, concurrent engineering design. it can not only

6、 applied to workstations, but can also be applied to a single machine.pro / e uses a module, can sketch, parts production, assembly design, sheet metal design, processing, and ensure that the user can choose to use according to their needs.1a parameter of the designrelative to the products, we can s

7、ee it as the geometric model, no matter how complex the geometry model can be decomposed into the composition of the limited number of characteristics, of each characteristic can be fully constrained with limited parameters, whichparameters of the basic concept. 2. feature-based modelingpro / e is a

8、 feature-based solid modeling system, the engineering staff with intelligent features of the model generated based on the characteristic function of cavity, shell, chamfered and rounded corners, you can freely sketching, and easily change the model. this features provide engineering designers never

9、had the design simple and flexible. 3. a single database (all related)pro / engineer is to establish the database on the unified grass-roots, unlike some of the traditional cad / cam system is built on multiple databases. the so-called single database, project information from a library in a product

10、 modeling work makes each individual user, whether he is what a department. in other words, changes occur in any one of the design process as a whole, and also before and after the reaction on the relevant link in the entire design process. for example, once the engineering detail change, nc (nc) to

11、ol path is automatically updated; assembly drawings any changes, exactly the same reaction in the three-dimensional model. this unique data structure and engineering design complete combination of a product designed to combine. this advantage, making the design more optimized, higher quality finishe

12、d product to better market, the price is cheaper.2. modeling of the bearingbearing modeling, including modeling of the cage, the modeling of the bearing inner ring, the bearing outer ring of the modeling and the modeling of ball bearings.2.1. cage modelingopen the proe / e election with the new part
