Abstract


The process design is an important part of large marine propeller manufacturing , has an important influence on product quality and manufacturing costs . Generated by the process design technology file and associated data is not only the basis of the manufacturing process , and production management and operational control systems on the basis of information sources . Since the propeller is a large space surface parts, so the calculation and processing of process parameters is very complex, cumbersome . Computer-Aided Process Planning ( CAPP ) for propeller processing systems research and development has a very important significance . Articles mainly in the following aspects: First , the current situation of the processing industry for domestic propeller , systems analysis and detailed summarizes the propeller processing technology knowledge . On this basis , the computer processing method of the process - related content . Second, the derivation and validation process value calculations for which the mathematical methods . Including the contents of the interpolation curve , coordinate transformation . Third, the proposed overall program of large - scale marine propeller CAPP system . Build a process report generation module , test data processing module, communication module main function modules . And the work involved in the module principles, programming carried out a detailed study and elaboration . The article uses Visual Basic 6.0 environment to develop the basic framework of process planning system , the use of interactive , relevant process design principles applied to the analysis of the process and the calculation of the main process parameters , the auxiliary process completed propeller process design . Proven , various process data generated by the propeller CAPP system is very accurate , fully meet the practical needs of the enterprise . The implementation and application of the CAPP system to optimize the propeller process design , to avoid duplication of engineering personnel , shortening the production cycle , improve the economic efficiency of enterprises .
