Abstract: The CAD/CAM system has played an important role in many aspects. This paper combines the development practice of the tooling management system of Wafangdian Bearing Co., Ltd., and focuses on the overall structure of the system and the entry, retrieval, modification and printing of the tooling schedule. The implementation of functions such as output, version management, and electronic signature hope to provide a reference for comrades who are doing similar development work.
Key words: tooling, CAD, PowerBuilder
0 Preface
Wafangdian Bearing Co., Ltd. is the largest
bearing manufacturer in China. {TodayHot} has nine series of bearing production capacity of more than 5,000 varieties. The technical documents of its products are very complicated, and it is very close to review, copy, use, save and update. inconvenient. In the increasingly fierce market competition, in order to strengthen the standardization of management and improve work efficiency, the use of computer management has become an inevitable choice. Dalian University of Technology and Wafangdian Bearing Co., Ltd. worked closely together to successfully develop the bearing CAD/CAPP system and achieved the expected results. This article will discuss in detail the composition, function and characteristics of the tooling management system.
1. The overall design of the bearing tooling management system
1.1 Functional requirements of the system
The function of the system is shown in Figure 1. It consists of three modules: tooling schedule management, password management, and tooling name table management.
2. Main functions and features of bearing tooling management system {HotTag}
In the development process, according to the actual situation of the tile axis, the human-machine interface adopts the format of the paper tooling list used in the actual use, and adopts the color configuration of “white paper black”, which makes the likes to eliminate the strangeness to the computer. Feeling and discomfort, enhance the friendliness of the interface, and in order to facilitate the likes and management, the four parts of the schedule use a consistent interface format.
2.1 data entry function
Since the tile axis has more than 5,000
bearing types, the amount of data to be entered is large. In order to ensure the fast, accurate and standardized input data, a drop-down sub-data window and a drop-down list box technique are adopted in the data window of the input interface. The specific instructions are as follows:
Drop-down sub-data window technology: Since the name items of each fixture's fixture or gage are basically similar, select the drop-down sub-data window attribute in the data window name item, increase the dynamic pull-down sub-data window function, and create the corresponding table to store The newly-created name, the new name can be entered once, the application will automatically remember and update the data content in the drop-down sub-data window. When you use it, you can enter the name by simply clicking the corresponding name item with the mouse. The data entry efficiency is obvious. Improve and make the names of different expressions in the actual use unified into a consistent name, which achieves the standardization of data entry and creates favorable conditions for computer processing data. The "a, b, f" symbols, which are often found in the main dimensions, also use the drop-down sub-data window technique to achieve the purpose of simplifying the entry.
Drop-down list box technology: For the "remarks" one of the two options - "base map original" and "new design" use a drop-down list box, just use the mouse to click the corresponding item.
Due to the use of the drop-down sub-data window, the data table has been added, and the addition and deletion management module for this table has been added accordingly, which has increased the development workload.
