Establishment of CAD 3D Standard Parts Library of Automobile Panel Die Based on ARX

The establishment of CAD dimension standard parts library of automobile cover mould based on ARX Lin Juguang Fang Guisheng Hong Guojun Mould Research Institute of Hefei University of Technology, Hefei 2300, Anhui, used the structural design part of the car cover mould 0 0. Through the modified internal data structure, using the method of ginseng and painting, the standard form of the buccal tool is automatically generated, and the conditions for the automatic generation of the assembly of the automobile segment cover mold are introduced. In the automobile cover mold, Mold structure design accounts for most of the design workload. Therefore, improving the efficiency of mold structure design plays an important role in improving the efficiency of the entire product design. In order to improve the quality and efficiency of mold milk. It is necessary to transfer the standard parts of the mold to the computer. The standard part-shaped library is built for the purpose of making molds and making calls, which lays a foundation for the automatic realization of the automatic assembly of the automobile cover parts. This article uses the combination of people and the way to use the menu and dialog resources to provide a good interactive interface for users, and adopts a tax-oriented object-oriented programming language. 1. It seems to be a modification, which is thirsty, 菘猓, cloud 谑di system, the same, the automatic drawing of the parametric shape of the standard parts of the mold.

1 Take the technical receipt date of 126 funds, and the target of Anhui Province. Funded project 96120032 into the application process refers to the sister, in the object-oriented programming environment 0 question, recognize the development of the process, compared with the long-awaited crime 5, people, the application is no longer an independent process, but a dynamic link Library. A command in which the person operates in the same way as the native command itself.

1.1 latch, the operating mechanism of the program, the application adopts a completely different operating mechanism from the human gamma 306, the user-designed human-like program and the call entry function 3, for example, and sends a load message to it, and then, through The 8-pass statement in the entry function calls the initialization function to complete the initialization of the program. This kind of operation mechanism makes the program run much more, and the program function is also enhanced.

1.2 Dynamic Linking and Static Linking, the person taking application has static and dynamic link modes when generating the dynamic link library with extension extension. In dynamic link mode, each application has a total of 1; 1 with 5 positive, dynamic Link library, this 40% of the program occupies a small amount of disk space, the memory space required for the runtime is also small, running fast, but the compiler used to generate the application must be used to build people, also 0 milk The compiler version is the same, otherwise the program may not work properly.

On the static link mode, each person seems to be in the application. The first one is the same as the one in the application. It has the above question, but the disadvantage is that the generated application has a large number of bytes and the memory capacity. The demand is large, and, because more data exchange is required, usually the program runs a dynamically linked application. 2. This article mainly uses static linking, and the basic structure and function of the 1.38 program use 1 redundant input. Its function is usually divided into two parts to realize the initialization part of the application initialization function of the human application; it is the main part of the program that realizes the specific function requirements of the application. The initialization part can be used as an independent, + source program file, the static link person takes the initialization part of the application mainly by the header file containing statements and external function descriptions and variable definition entry function definition 30 pool, initialization function 释放 and release library function, Define the load function and the unloading, the function definition of the program and so on. The entry function value uses 8 spit statements to perform related actions and returns a status code. It is mainly used to call the 0 blood function to load the dynamic link library into the memory and call the 33 Jia 1 function to get the people. The problem is to release the memory occupied by the MFC library when the ARX application is uninstalled. The load and unload functions are mainly to add and remove user-defined new commands to the AUtoCAD system command heap.

2 Take the program in the multi-document menu and dialog box to achieve the class 1 Kuna and advanced from the ++ programming language and a few, convenient and effective design of the typical Jiashan 8 in the application of the realization of the shirt document and menu resources The example seven program that can still help the fairy tales is in the catalogue. 3 Mushan 55, 18, 1 out, Di modified dishes 1 will be converted into the factory's own menu. If the user needs to change the menu culture, you can change the menu resource property item to 1 and his 8 language bar 1 job 6 and change it to 0686. Only. 0, at the same time, the project setting 136 out of the resource item in the language column 13 to float 13 to Chinese if the user wants to add dialog resources in the application, create a mode dialog and modeless dialogue, refer to the example of 01. The multi-document and menu resources compiled by the wide program 1. and 1 are loaded, and the menu user interface obtained after running is loaded in 0 or 01.

3 application examples are automatically drawn. The following is an example of the automatic generation process of the guide pillar guide profile, which specifies the creation process of the hack-based human application.

318, the creation of the application, Nazhou 1 created 4 application printing framework. In the item option, select 1 to enter the item name, but the factory 7 material selection 3.018.13 positive 0 = set the application initialization part, according to the elbow redundancy person to take the application structure requirements, add the corresponding header file function description and variables Definition, etc.

Add dialog resources to the project file and edit the layout and properties of the dialog. 23 is the dialog resource used when drawing the guide bush guide.

Create a post; this is like a Weige shape. A noisy pavilion is available. The heart 10 is drawn and then converted into a data member and a member object definition of the bit control, the data member is used to store the value of the control, and the member object is an instance of a control class. The data members and member objects set here are mainly used to set parameters, and other parameters are determined according to the values ​​of the main parameters. 2. Determine the value of 1 according to the value of the main parameter, and select the length value of 1 according to the combo box.

Initialize the data in the column box.

Add corresponding message processing functions, including the selection of drawing parameters and the generation of shapes.

In the Type, select the customization option, and change the extension of the input file name to the muscle and enter the linker in the edit box to include the human library file, such as 8031. This database access library, 3. This command extends the library 13 to run the extension library, 3, the interface interface library, and 13 bands. 13 general geometry library, this 3, 1.135 boundary description library, etc.

3686 changed to 0000000, dynamic link external stab starting address beer, 0 is 1 also, 1 changed to blood, such as 233 program loading and running created program is loaded and run, set the corresponding parameter 3 in the dialog box, select draw Dimension command control, automatically generated guide sleeve shape such as 441.

4 Conclusions It has been applied to the creation of the standard part library of the automobile cover mold structure design, and received good results. When the 4 guide sleeves are colored, the sample is also suitable for the establishment of fat, 塍, d, l libraries, such as gear bearing couplings, etc., thereby saving a lot of manpower and material resources for the enterprise, and having a practical price.
