| This subject comes from Xiamen major projects of science and technology: Technological Development&Industrial Application of Solid Carbide Tool in Processing Aviation Aluminum Alloys.This paper first analyses the research status and development trend of CAPP system, then it summarizes the processing characteristics of Aviation Aluminum Alloy structural parts with group technology. In this paper, Aviation Aluminum Alloy structural parts are coded and classified. Meanwhile, the processing of different characteristic structure of Aviation Aluminum Alloy structural parts is analysised. After that, The cutting technology database and CAPP system of Aviation Aluminum Alloy are established. The system can derive a new technology using the similarity between a new part and the existing parts. The technology of a new part can be obtained after revising the deriving technology. The main research contents are as follow:(1) The cutting technology database of Aviation Aluminum Alloy is established in SQL Server2008, which includes the workpiece, material, machine information of Aviation Aluminum Alloy and so on.(2) A new part classification and coding system fitting Aviation Aluminum Alloy structural parts is established with the existing JLBM-1system. This system can be used to code the Aviation Aluminum Alloy structural parts.6hexadecimal figures are used to represent the key feature, which can represent as many as24kinds of features.(3) The similarity of Aviation Aluminum Alloy structural parts is calculated based on the technology of part similarity grouping to realize the function of technology query and deriving.(4) The cutting technology CAPP system of Aviation Aluminum Alloy is established in Visual Studio2010, which includes information query module, technology data management module, technology information output module and technology designing module. |
