Abstract

Abstract: By analyzing the key components feature similarity of different types marine diesel，similar machining feature，process and tool path of marine diesel key components were summarized.CAD/CAPP/CAM integrated technology of marine diesel key components was studied based on feature similarity，and feature machining template library was set up.Through dynamic combination of feature machining templates，the sharing and reuse of feature machining templates in CAD/CAPP/CAM integrated system were realized，and the results were verified by practicle examples.This system not only solved repetitive operations of similar manufacturing objects in CAD/CAPP/CAM integrated system，such as process reasoning，tool path planning，which reduced repetitions in manufacturing process and enhanced generality of CAD/CAPP/CAM integrated system，but also had good reference meaning to similarity utilizing in CAD/CAPP/CAM integrated system of other complex parts.

Key words: marine diesel key components, CAD/CAPP/CAM integrated system, feature similarity theory, feature machining template
